Everyone loves music. Music is everywhere, it pervades our world. Everyone knows music has power and importance. But have you ever stopped to consider why? What it is about music that gives it so much power and importance?

Here are seven top reasons:

  1. Music is a universal language. It inspires common human feelings and bridges gaps between cultures that spoken languages cannot. It brings people together and creates universal community.
  2. Music inspires and evokes emotion in a healthy way. It touches our emotional being and evokes moods and feelings that are sometimes difficult to express. It can change a difficult mood and make it happy or excited; it can change a light mood and take it deeper and more profound.
  3. Music enhances learning and makes it more enjoyable. It is scientifically proven that music enhances brain functioning. Playing music uses many brain functions simultaneously: motor control, imagination, hearing, sight, memory, etc.
  4. Music creates ambiance. You can use music in any environment to enhance and augment what is already there. Consider the difference between a party with music and one without, or a sporting event, or a movie, or a romantic restaurant, or driving in your car…
  5. Music is spiritual. Music is of the spirit and inspirational to the spirit. All religions use music to help express spiritual values, and all religions use music to uplift the spirit.
  6. Music sparks the imagination. It invokes mental imagery and inner scenery that opens the mind to amazing insight and spans the distance between the stars.
  7. Music is a simple pleasure. All it takes is your ears and your imagination.

I believe that at the center of the phenomenon of the magic that music creates is the spiritual aspect. Music is a gift from God, a sacred expression of the Universal Life Force Energy that creates us all.

Reminiscing about the good old days when we were growing up is a memory trip well worth taking, when trying to understand the issues facing the children of today. A mere 20 years ago, children used to play outside all day, riding bikes, playing sports and building forts. Masters of imaginary games, children of the past created their own form of play that didn’t require costly equipment or parental supervision. Children of the past moved… a lot, and their sensory world was nature based and simple. In the past, family time was often spent doing chores, and children had expectations to meet on a daily basis. The dining room table was a central place where families came together to eat and talk about their day, and after dinner became the center for baking, crafts and homework.

Today’s families are different. Technology’s impact on the 21st century family is fracturing its very foundation, and causing a disintegration of core values that long ago were what held families together. Juggling work, home and community lives, parents now rely heavily on communication, information and transportation technology to make their lives faster and more efficient. Entertainment technology (TV, internet, videogames, iPods) has advanced so rapidly, that families have scarcely noticed the significant impact and changes to their family structure and lifestyles. A 2010 Kaiser Foundation study showed that elementary aged children use on average 8 hours per day of entertainment technology, 75% of these children have TV’s in their bedrooms, and 50% of North American homes have the TV on all day. Add emails, cell phones, internet surfing, and chat lines, and we begin to see the pervasive aspects of technology on our home lives and family milieu. Gone is dining room table conversation, replaced by the “big screen” and take out. Children now rely on technology for the majority of their play, grossly limiting challenges to their creativity and imaginations, as well as limiting necessary challenges to their bodies to achieve optimal sensory and motor development. Sedentary bodies bombarded with chaotic sensory stimulation, are resulting in delays in attaining child developmental milestones, with subsequent impact on basic foundation skills for achieving literacy. Hard wired for high speed, today’s young are entering school struggling with self regulation and attention skills necessary for learning, eventually becoming significant behavior management problems for teachers in the classroom.

So what is the impact of technology on the developing child? Children’s developing sensory and motor systems have biologically not evolved to accommodate this sedentary, yet frenzied and chaotic nature of today’s technology. The impact of rapidly advancing technology on the developing child has seen an increase of physical, psychological and behavior disorders that the health and education systems are just beginning to detect, much less understand. Child obesity and diabetes are now national epidemics in both Canada and the US. Diagnoses of ADHD, autism, coordination disorder, sensory processing disorder, anxiety, depression, and sleep disorders can be causally linked to technology overuse, and are increasing at an alarming rate. An urgent closer look at the critical factors for meeting developmental milestones, and the subsequent impact of technology on those factors, would assist parents, teachers and health professionals to better understand the complexities of this issue, and help create effective strategies to reduce technology use. The three critical factors for healthy physical and psychological child development are movement, touch and connection to other humans. Movement, touch and connection are forms of essential sensory input that are integral for the eventual development of a child’s motor and attachment systems. When movement, touch and connection are deprived, devastating consequences occur.

Young children require 3-4 hours per day of active rough and tumble play to achieve adequate sensory stimulation to their vestibular, proprioceptive and tactile systems for normal development. The critical period for attachment development is 0-7 months, where the infant-parent bond is best facilitated by close contact with the primary parent, and lots of eye contact. These types of sensory inputs ensure normal development of posture, bilateral coordination, optimal arousal states and self regulation necessary for achieving foundation skills for eventual school entry. Infants with low tone, toddlers failing to reach motor milestones, and children who are unable to pay attention or achieve basic foundation skills for literacy, are frequent visitors to pediatric physiotherapy and occupational therapy clinics. The use of safety restraint devices such as infant bucket seats and toddler carrying packs and strollers, have further limited movement, touch and connection, as have TV and videogame overuse. Many of today’s parents perceive outdoor play is ‘unsafe’, further limiting essential developmental components usually attained in outdoor rough and tumble play. Dr. Ashley Montagu, who has extensively studied the developing tactile sensory system, reports that when infants are deprived of human connection and touch, they fail to thrive and many eventually die. Dr. Montagu states that touch deprived infants develop into toddlers who exhibit excessive agitation and anxiety, and may become depressed by early childhood.

As children are connecting more and more to technology, society is seeing a disconnect from themselves, others and nature. As little children develop and form their identities, they often are incapable of discerning whether they are the “killing machine” seen on TV and in videogames, or just a shy and lonely little kid in need of a friend. TV and videogame addiction is causing an irreversible worldwide epidemic of mental and physical health disorders, yet we all find excuses to continue. Where 100 years ago we needed to move to survive, we are now under the assumption we need technology to survive. The catch is that technology is killing what we love the most…connection with other human beings. The critical period for attachment formation is 0 – 7 months of age. Attachment or connection is the formation of a primary bond between the developing infant and parent, and is integral to that developing child’s sense of security and safety. Healthy attachment formation results in a happy and calm child. Disruption or neglect of primary attachment results in an anxious and agitated child. Family over use of technology is gravely affecting not only early attachment formation, but also impacting negatively on child psychological and behavioral health.

Further analysis of the impact of technology on the developing child indicates that while the vestibular, proprioceptive, tactile and attachment systems are under stimulated, the visual and auditory sensory systems are in “overload”. This sensory imbalance creates huge problems in overall neurological development, as the brain’s anatomy, chemistry and pathways become permanently altered and impaired. Young children who are exposed to violence through TV and videogames are in a high state of adrenalin and stress, as the body does not know that what they are watching is not real. Children who overuse technology report persistent body sensations of overall “shaking”, increased breathing and heart rate, and a general state of “unease”. This can best be described as a persistent hypervigalent sensory system, still “on alert” for the oncoming assault from videogame characters. While the long term effects of this chronic state of stress in the developing child are unknown, we do know that chronic stress in adults results in a weakened immune system and a variety of serious diseases and disorders. Prolonged visual fixation on a fixed distance, two dimensional screen grossly limits ocular development necessary for eventual printing and reading. Consider the difference between visual location on a variety of different shaped and sized objects in the near and far distance (such as practiced in outdoor play), as opposed to looking at a fixed distance glowing screen. This rapid intensity, frequency and duration of visual and auditory stimulation results in a “hard wiring” of the child’s sensory system for high speed, with subsequent devastating effects on a child’s ability to imagine, attend and focus on academic tasks. Dr. Dimitri Christakis found that each hour of TV watched daily between the ages of 0 and 7 years equated to a 10% increase in attention problems by age seven years.

In 2001 the American Academy of Pediatrics issued a policy statement recommending that children less than two years of age should not use any technology, yet toddlers 0 to 2 years of age average 2.2 hours of TV per day. The Academy further recommended that children older than two should restrict usage to one hour per day if they have any physical, psychological or behavioral problems, and two hours per day maximum if they don’t, yet parents of elementary children are allowing 8 hours per day. France has gone so far as to eliminate all “baby TV” due to the detrimental effects on child development. How can parents continue to live in a world where they know what is bad for their children, yet do nothing to help them? It appears that today’s families have been pulled into the “Virtual Reality Dream”, where everyone believes that life is something that requires an escape. The immediate gratification received from ongoing use of TV, videogame and internet technology, has replaced the desire for human connection.

It’s important to come together as parents, teachers and therapists to help society “wake up” and see the devastating effects technology is having not only on our child’s physical, psychological and behavioral health, but also on their ability to learn and sustain personal and family relationships. While technology is a train that will continually move forward, knowledge regarding its detrimental effects, and action taken toward balancing the use of technology with exercise and family time, will work toward sustaining our children, as well as saving our world. While no one can argue the benefits of advanced technology in today’s world, connection to these devices may have resulted in a disconnection from what society should value most, children. Rather than hugging, playing, rough housing, and conversing with children, parents are increasingly resorting to providing their children with more videogames, TV’s in the car, and the latest iPods and cell phone devices, creating a deep and widening chasm between parent and child.

Cris Rowan, pediatric occupational therapist and child development expert has developed a concept termed ‘Balanced Technology Management’ (BTM) where parents manage balance between activities children need for growth and success with technology use. Rowan’s company Zone’in Programs Inc. http://www.zonein.ca has developed a ‘System of Solutions’ for addressing technology overuse in children through the creation of Zone’in Products, Workshops, Training and Consultation services.

What does the term ethnic food mean to you? To me, I think of the different countries and the cuisines they have to offer. One such type of food that greatly prevails all others is Indian Food. Well what does Indian cuisine consist of you may ask? Indian food is derived from India and uses a blend of subtle herbs and spices. In this form of cooking, there is a great amount of variation in the meat, vegetables, and spices used. The majority of Indian cooking is made up of vegetables and yet there are several meat and poultry dishes as well. Within India, there are two main yet distinct methods of cooking seen in both North India and South India.

Common Food Found in Northern India:

– roti: a traditional Indian flat bread eaten with Indian curries or cooked vegetables

– naan: resembles the western “pita” bread and is eaten with Indian curries or cooked vegetables as well

– kulcha: another form of tasty flat bread, usually found from Punjab

– tandoori chicken: form of chicken that is marinated in yogurt and tandoori spices, it is cooked in a large clay oven

– palak paneer: cooked spinach with minor cheese cubes and marinated with curry powder

– channa masala: chickpeas smothered in zesty sauce and marinated with curry powders and masalas

Common Food Found in Southern India:

– dosa: a type of South Indian crepe and made from rice and black lentil

– idli: a small spongy cake made from rice and black lentil

– vada: a small snack made from lentils and containing small pieces of onions as well as green chilies

– sambar: a thick spicy soup consisting of lentils and vegetables

As you can see, the above dishes are quite unique from western foods such as hamburgers and fries. In Northern India, there is a considerable amount of curry powder used in specific items. Whereas in South India, the spices are not strong and are much less filling than North Indian food.

What is advertising?

It is hard to find a satisfactory definition of advertising.

A picturesque way of putting it is to call it business imagination, an imagination that sees in a product possibilities which can be realized only by appealing to the public in new ways to create a desire where none existed before. It is a very broad word, an omnibus word conveying different ideas to different people.

No advertising definition is here possible except as this entire article may be accepted as a definition. So rapidly has advertising advanced through its various changes that even the latest dictionaries and encyclopedias are out of date in their attempts to define it. The advertising of yesterday is not the advertising of today. Men not so very old have witnessed its entire development from an untrustworthy instrument of quacks to its place as an engine in the conduct and expansion of business.

Advertising in the dictionary sense has a history as old as that of the human race. Just as soon as there were enough people in the world, some sort of formal announcement had to be made. The early history of such announcements – from proclamations to the beginning of pictorial and lettered inscriptions, from these primitive posters to the discovery of printing, and from the advent of printing to the beginning of real advertising – is of interest only to the archaeologist. It is of no value to the business entrepreneur. It would be of no assistance to understanding modern advertising than ancient Phoenicians coins would be to comprehending the principles of a modern bank.

Every attempt to secure the sale of a product or service is advertising. The wares of the primitive merchant displayed invitingly in front of his booth is advertising. A want ad, to secure a job or an employee, is advertising. An inscription on a wall, the barker in front of a side show, the promises of an internet marketer, the announcement of a new online technology, membership in an affiliate program, wearing a peculiar shirt or distinctive sticker in your car – all these are forms of advertising in that they seek to attract attention to a product or a service that is for sale. For a product or a service of general use, rich and poor, high and low, men, women and even children, must be appealed to.

At least one principle we know of, stays constant, not eroding with the passing of time or the use and or abuse of men, not concerned with the weather outside, nor considering your personal health status, or taking into account your surrounding circumstances, and that is that you have to keep doing it, it has to be fed, no way around it, it keeps asking for every ounce of your commitment if you expect any kind of visible returns.

Whatever the appropriate definition of advertisement is, one thing is to conclude, it is because it has been. And every succeeding year since the beginning of the human entrepreneurship it has left its precious deposit of new ideas, better methods, larger and swifter efficiency, and the promise of an even greater growth.

 

International travel can be a great experience; it allows you to witness many new cultures and lifestyles. International travel has many benefits which make it better than your traditional domestic vacation. Depending on your destination, traveling abroad can also save you money because of the current exchange rate. These rates change and may not be available in the future. A good exchange rate or activity that you would like to see may not be available if you put off planning the vacation. Another benefit of planning an international trip today is the current technology, which makes booking a trip easy. Technology can help eliminate the hassle of finding the best prices and locations based on your budget.

Traveling, whether for a long weekend away to a nearby country, or clear across the globe, is invigorating, refreshing and expands so much in one’s life that it is something that more people should do. Traveling abroad can greatly change your life for the better because there are many cultures and lifestyles to experience. These cultures can provide you with an entirely new perspective on life. Once you begin experiencing the beauty of the world, you may even begin planning yearly international vacations.

Currency rates fluctuate regularly and, as stated before, this may be a good reason to plan an international vacation today. Money is necessary if you are planning to travel and see the sights the country has to offer. If your currency can be exchanged at a reasonable rate, this can greatly improve your vacation experience. This is an important reason for traveling internationally now since you can get the most out of your trip. If you put the trip off the exchange rate may change for the worse and you can lose money after arriving at your destination.

Practical reasons

However, let us get down to the more practical reasons for traveling internationally. Frankly, it is understandable why most people would be hesitant to travel now. The economy appears to be in bad shape and many people are trying to save money. However, in some instances, this can be beneficial for travel, the airlines may lower their prices in order to get your business and this can save you money. Airline prices also fluctuate between airlines and by looking around you may find a special promotional vacation package that may not be available in the future.

Vacations are meant to be fun and enjoyable and this is another reason for traveling abroad today. There are many locations to visit from the beaches of the Caribbean to the beautiful and exquisite city of Paris, France. Experiencing something new is always the best way to live and an international vacation provides just that. This can spice up your life by allowing you to find things that you would not normally consider trying.

In fact, these days traveling is so much easier, more efficient and less time consuming than it used to be. We can travel across the globe faster and it requires much less energy than was required years ago. It is also possible watch TV, movies or listening to music while traveling. On some airlines, you can even follow the path of your airplane via satellite!

Technology and travel

Due to the technology available, planning a vacation can be stress-free as well. By using the internet to purchase your international flight tickets, you can plan your trip, get travel advice, and shop around for great deals. Technology has come a long way especially for finding the best travel packages. You can book your hotel, car, flight, and even your entertainment all on one website. If you are unsure of your destination, you can browse through the millions of videos and pictures of different locations to find which location best suits you. Planning an international trip can be an enjoyable experience when compared to the hassle involved years ago.

It is highly recommended to travel abroad at least once in your life and there are many benefits to planning your trip now. Saving money is the main reason for planning your trip today. When traveling abroad, you may have to exchange your money for the local currency. Currency exchange rates change frequently and this can have a large impact on your vacation. Since you do not know what the rates are going to be in the future, it is best to plan your trip while a good rate is available. You should also consider planning a trip because of the cultural value. Experiencing new cultures and lifestyles can help provide much value to your life. It may even change your life completely because you may find something new that you like. If you are planning an international trip, you should consider these suggestions because they can help you get the most out of your trip.

 

When it comes to the choice between using an online travel agency or not for your next trip, there are several factors to consider with several pros and cons.

One of the main concerns that seem to arise with online travel agencies is the trustworthiness and security of paying such large amounts of money online. While online security is a major factor for any online travel agency, this is true of all online businesses. So it is more a matter of choosing a travel agency online with a quality reputation by looking at their customer reviews and see what their actual site itself is like. What’s more, when you are logging on and preparing to pay for any online costs, there should always be that small symbol of a lock at the bottom right hand side of the screen as a sign of the level of security attached.

The benefits of using online travel agencies are that unlike their physical counterparts, they are available at any time, ideal for emergency travel situations, and also for any late after-hours bookings that you need to complete. Additionally you can compare travel deals and special available all over the world in order to find the very best deal for you and your travels. What this means is that while a physical travel agency will have a great range of deals for you, they are limited by who they can work with in terms of other travel professionals. With these online agencies, it up to you to decide who you work with, allowing you to create your ideal travel plans.

What you may also find when working with online travel agencies that you will have a great range of methods to pay for the holiday, offering greater flexibility and financial choice. These choices can range from the standard credit cards and accounts to payment plans and travel accounts.

Overall when talking online travel agencies it is more a matter of preference of the customer and how they prefer to do their business, either online or in person, that should dictate how they book their travel plans.

 

My Six Figure Lifestyle was Chuck Marshal’s up-front profits and residual income program through postcards. It has since evolved into The Secret Formula Teleseminar, a newer $1,497 system that calls itself an alternative for the 95% of people who feel lied to, dissatisfied, confused and angry by the “biz opps” industry.

The Approach

The Secret Formula Seminar (formerly My Six Figure Lifestyle) has been developed by Rob Stinson, a one-time machinist who candidly uses his regular-guy persona to share how his “Secret Formula” now has up to 150,000 distributors and results of over $250 million worth of products sold.

The Difference

Stinson states that what differentiates his teleseminar and software from the rest is that they’re designed to attract what he calls Business-Opportunity-Buyer (BOB) prospects. These prospects appear to consist of owners and managers of existing businesses looking to build up sophisticated streams of multiple income channels, instead of friends, relatives or co-workers who tend to drop out of these programs.

The Promise

Per his website, Stinson promises up to a five-figure income within the first few months, no time wasted with scheduling, presentations, selling, pitching or closings, and less than two hours spent daily on the business when owners work the systems properly.

Stinson’s new My Six Figure Lifestyle program appears to include:

– 700 to 1,500 qualified, worthwhile leads

– Lead generation and prospecting software and branded marketing system

– Postcard lead-generating manual for generating leads used with My Six Figure Lifestyle

– Additional software incentives

My Six Figure Lifestyle / The Secret Formula Seminar In Review

Stinson appears to believe that by being upfront about frustrations and potential scams prospective customers have experienced, The Secret Formula Seminar may have the ability to attract those that have since rejected online business opportunities.

The newly revised “My Six Figure Lifestyle” program, now known as The Secret Formula Seminar, is reported to cost $1,497 to join. The program seems to work on a teleseminar type system and is said to include a handful of different items and features. Some of them include pre-qualified leads, proven marketing software and systems and manuals and incentives.

As with any and all online based business endeavors; it is highly recommend that one does their own research before investing actual monies into a program. The Internet is a very large and uncontrolled atmosphere that requires caution and in-depth research; especially when being asked for monies in return for a service, membership or product. That’s not to say that real and lucrative opportunities don’t exist out there; one just needs to exercise caution when looking for that perfect one to ensure it is a legitimate opportunity and delivers on what it says for how much it says.

You might be surprised to learn that there are different types of locksmiths around. This is essential especially for those who want a more specialized service. Residential, commercial, automotive and forensics are the types of locksmiths that are accessible although the forensic ones are rare as they usually work with investigative agencies or law enforcement agencies.

Residential

Residential locksmiths are experts when it comes to making the home safe and secure. As most homes have the regular locks installed near window frames, it might compromise the safety of the family. These experts can install a double cylinder lock that needs a key inside for the door to open to give extra security. Aside from this base-knowledge they can also re-key locks as well as have them replaced in such a way that these are not easily tampered. They can also do entry gates, screen doors, sliding as well as emergency services.

Commercial

A commercial locksmith specializes in locks that are manufactured for business purposes. Examples would be installation of panic bars, replacing locks in file cabinets, installation of automatic door closer, safe/vault installation as well as installing a master-key system. Panic bars are especially important as they would provide workers a means to exit the building premises in case of emergencies.

Automotive

Automotive locksmiths are the ones that you go to if you ever need a spare car key or want a replacement when you’ve lost the original car key. These experts can help automotive owners in choosing the right type of car keys that would best suit their needs. Most automotive locksmiths are familiar with transponder car keys and can also do re-programming at a lower price compared to the same service that car dealers offer. Aside from transponders, they can also unlock cars, change or replace ignition locks, provide laser cut keys and even offer lock services for high security vehicles.

Services

In choosing the locksmith that would best suit your need(s), it is important to deal with a company that is licensed and has done background checks on their employees. This is to make sure that the company that you would be transacting with is legal and since some items in the house might be valuable or important documents are inside vaults or safes, one is assured that the person they are dealing with is someone who they can trust. Consider talking with someone who knows a reputable locksmith especially if you’ve just moved in or purchased a new home or office.

The KWP2000 protocol has become a de facto standard in automotive diagnostic applications. It is standardized as ISO 14230-3. KWP2000 describes the implementation of various diagnostic services you can accethrough the protocol. You can run KWP2000 on several transport layers such as K-line (serial) or CAN.

Transport Protocol

As KWP2000 uses messages of variable byte lengths, a transport protocol is necessary on layers with only a well defined (short) message length, such as CAN. The transport protocol splits a long KWP2000 message into pieces that can be transferred over the network and reassembles those pieces to recover the original message.

KWP2000 runs on CAN on various transport protocols such as ISO TP (ISO 15765-2), TP 1.6, TP 2. 0 (Volkswagen), and SAE J1939-21. For KWP2000, the Automotive Diagnostic Command Set supports only the ISO TP (standardized in ISO 15765-2) and manufacturer-specific VW TP 2.0 transport protocols.

Diagnostic Services

The diagnostic services available in KWP2000 are grouped in functional units and identified by a one-byte code (ServiceId). The standard does not define all codes; for some codes, the standard refers to other SAE or ISO standards, and some are reserved for manufacturer-specific extensions. The Automotive Diagnostic Command Set supports the following services:

• Diagnostic Management

• Data Transmission

• Stored Data Transmission (Diagnostic Trouble Codes)

• Input/Output Control

• Remote Activation of Routine

Upload/Download and Extended services are not part of the Automotive Diagnostic Command Set.

Diagnostic Service Format

Diagnostic services have a common message format. Each service defines a Request Message, Positive Response Message, and Negative Response Message. The Request Message has the ServiceId as first byte, plus additional service-defined parameters. The Positive Response Message has an echo of the ServiceId with bit 6 set as first byte, plus the service-defined response parameters.

The Negative Response Message is usually a three-byte message: it has the Negative Response ServiceId as first byte, an echo of the original ServiceId as second byte, and a ResponseCode as third byte. The only exception to this format is the negative response to an EscapeCode service; here, the third byte is an echo of the user-defined service code, and the fourth byte is the ResponseCode. The KWP2000 standard partly defines the ResponseCodes, but there is room left for manufacturer-specific extensions. For some of the ResponseCodes, KWP2000 defines an error handling procedure. Because both positive and negative responses have an echo of the requested service, you can always assign the responses to their corresponding request.

Connect/Disconnect

KWP2000 expects a diagnostic session to be started with StartDiagnosticSession and terminated with StopDiagnosticSession. However, StartDiagnosticSession has a DiagnosticMode parameter that determines the diagnostic session type. Depending on this type, the ECU may or may not support other diagnostic services, or operate in a restricted mode where not all ECU functions are available. The DiagnosticMode parameter values are manufacturer specific and not defined in the standard. For a diagnostic session to remain active, it must execute the TesterPresent service periodically if no other service is executed. If the TesterPresent service is missing for a certain period of time, the diagnostic session is terminated, and the ECU returns to normal operation mode.

GetSeed/Unlock

A GetSeed/Unlock mechanism may protect some diagnostic services. However, the applicable services are left to the manufacturer and not defined by the standard.You can execute the GetSeed/Unlock mechanism through the SecurityAccess service. This defines several levels of security, but the manufacturer assigns these levels to certain services.

Read/Write Memory

Use the Read/WriteMemoryByAddress services to upload/download data to certain memory addresses on an ECU. The address is a three-byte quantity in KWP2000 and a five-byte quantity (four-byte address and one-byte extension) in the calibration protocols. The Upload/Download functional unit services are highly manufacturer specific and not well defined in the standard, so they are not a good way to provide a general upload/download mechanism.

Measurements

Use the ReadDataByLocal/CommonIdentifier services to access ECU data in a way similar to a DAQ list. A Local/CommonIdentifier describes a list of ECU quantities that are then transferred from the ECU to the tester. The transfer can be either single value or periodic, with a slow, medium, or fast transfer rate. The transfer rates are manufacturer specific; you can use the SetDataRates service to set them, but this setting is manufacturer specific. The Automotive Diagnostic Command Set supports single-point measurements.

Diagnostic Trouble Codes

A major diagnostic feature is the readout of Diagnostic Trouble Codes (DTCs). KWP2000 defines several services that access DTCs based on their group or status.

Input/Output Control

KWP2000 defines services to modify internal or external ECU signals. One example is redirecting ECU sensor inputs to stimulated signals. The control parameters of these commands are manufacturer specific and not defined in the standard.

Remote Activation of a Routine

These services are similar to the ActionService and DiagService functions of CCP. You can invoke an ECU internal routine identified by a Local/CommonIdentifier or a memory address. Contrary to the CCP case, execution of this routine can be asynchronous; that is, there are separate Start, Stop, and RequestResult services. The control parameters of these commands are manufacturer specific and not defined in the standard.
