Vehicle Diagnostic is not a new technology. In fact, it has been around for quite some time but it only recently came to the attention of car owners everywhere when General Motors and Chrysler introduced it. It basically entails an electronic device in your vehicle that monitors several aspects of your vehicle’s performance. How it works. Vehicle Diagnostic includes four main components. They are:
Some of these simply require that you sign up for the service online; some entail paying a fee. If you have questions about your vehicle’s diagnostic needs, you can call your dealer or manufacturer. They will be able to assist you or refer you to a technician who is knowledgeable about vehicle diagnostics and can perform the services you need. But if you prefer to perform the diagnostic procedure yourself, there are plenty of guides available in the market for your assistance. Here are some vehicle diagnostics basics:
On-board Diagnostic – This includes real-time data regarding your vehicle’s engine, gearbox, transmission, brakes, exhaust system, and more. Its real-time data is often referred to as OBD II (on-board diagnostics). A wide number of vehicle manufacturers have their own on-board diagnostics system. Many of them offer real-time service for free. However, some of them offer real-time services as part of a paid service or may charge a one-time fee.
Pre-owners manual – This is a book that comes with the vehicle. This contains information such as vehicle issues, troubleshooting tips and guidelines, and repair guides. This also provides the basic knowledge of vehicle diagnostics. It is recommended to have this book. However, it is not a substitute for a proper guidebook. You should have an authentic source for learning about various vehicle issues and safety concerns.
OEM or vehicle equipment pack – Automotive aftermarket offers a variety of new parts that are specially made to work with specific vehicle models. It is important to choose the right ones. OEM parts do not carry any claims or guarantees. These are for informational purposes only. It is best to consult an expert for advice concerning specific vehicle issues.
Real-time device – A real-time device is a program that is installed on your computer and can be accessed from anywhere in the world. Most real-time diagnostics programs come with a CD-ROM or flash drive. These devices allow you to monitor the condition of your car in real time. The device is similar to a console in a vehicle. It can display multiple data simultaneously. It is easy to use and requires no training or expertise.
Telematics – A telematics system is a vehicle diagnostic information system that allows on-board maintenance personnel to remotely control engine instruments such as fuel systems and oil pressure monitors. This enables technicians to service various on-board components while on the move. Major benefits of this system include reduced downtime, better accuracy and faster service times. Some common telematics components include diagnostic trouble codes, fuel management, airbags, tire pressure monitoring, emission testing and air conditioning control.
Not all vehicle manufacturers employ all of these diagnostics technologies. Most vehicle telematics solutions diagnostic tools come pre-installed with the vehicles they are designed to work with. However, most modern cars now come equipped with on-board diagnostics systems that are linked to a centralized station that receives and transmits data to various data acquisition units. Vehicle telematics software, vehicle diagnostics cards, instrumentation, and a network of on-board sensors and communication links together to form a fully functional and cost-effective on-board diagnostics system.
Vehicle issues can range from simple problems such as oil leaks to much more complex issues such as engine problems. In some instances, vehicle issues can even be prevented. For instance, if the vehicle’s airbag is activated during a crash, then the driver should manually release the seat belt before striking the steering wheel. The purpose of these safety features is to ensure that if anyone is injured during a collision, the person will not be trapped inside the vehicle. These and many more in-depth vehicle issues are what make using a car troubleshooting and vehicle diagnostics program so important.
Most on-board vehicle diagnostic information systems come standard with udsc (unified diagnostics status) modes. In simple terms, use modes allow for both data logging and fault code mapping; two of the most effective ways to gather information on a potential vehicle problem. Fault data is important because it is used to identify and resolve possible sources of a vehicle’s in-performance. In addition to the data logging, fault codes can also be used to isolate and monitor a specific part or system problem; a process that is both very useful in preventing common problems and saving time and money in fixing them.
Most of today’s on-board diagnostics systems come standard with both PCM (portable vehicle monitoring) and DSMS (digital electronic system) modes. With both of these modes, an on-board computerized system will read the battery voltage, fuel pressure, tire pressure and many other parameters and connect them to the computer. The computer then interprets the data and compares it with the parameters stored within the vehicle’s computer system database and then creates a detailed visual display of the data gathered – which is what you see on your LCD screen when you are troubleshooting your vehicle.
