subject: What Are Diagnostic Codes? [print this page] Diagnostic codes are your car's way of telling the mechanic what is wrong with it. The issue with these codes is the sheer number of them that are programmed into the vehicle's memory. Auto repair can be made easy, but this is contingent on the mechanic's ability to translate and read the codes. The specific language that the car uses is referred to as OBD. This stands for On Board Diagnostics.
OBD is a language that uses numeric codes to inform the mechanic what is wrong with the vehicle. If using an ASE master technician, they will have a specific device that is able to tap into the car's code and tell them where to find the issue with the vehicle. The layperson has the ability to use this same device on their own. One can purchase these devices at a car repair shop or car parts store. They are relatively affordable with the top end hand held devices being under $100.
Numeric Codes
Once the device has been plugged into the vehicle, a numeric code will be displayed on the screen. This code is used in order to tell the mechanic what is wrong with the vehicle; so that troubleshooting issues becomes easier. Many times the vehicle will tell the owner there is an issue that needs to be addressed before it becomes a huge problem. It does this by setting off the check engine light when the car is first turned on. This light can indicate simple to very complex issues with the engine.
Leaving it to the Pros
Manufacturers suggest that the codes and subsequent repairs be made only by licensed ASE mechanics. Although many sites like AAA have a listing of the many diagnostic codes which will allow the do it yourselfer to have an upper hand in the game. After all, if it a simple oil change or new filter, why spend hundreds of dollars for a mechanic? This is not to say that all auto repair should be done by the novice. rather, it is stating that if the auto repair is simple enough saving a few bucks is good.
DIY Becomes More Popular
Diagnostic codes have been able to streamline the world of auto repair. No longer does the ASE master technician have to spend hours tracking every possible issue to an existent problem with the vehicle's engine. they now have the ability to pinpoint where the problem lies and deal with the issue quickly. This not only allows them to be more productive, it also allows the consumer to save money on the actual repairs and avoid unnecessary fixes that will not eradicate the problems.
Diagnostic codes and the system that supports them have been installed in all new cars since about 1996. The manufacturers automatically install this system into vehicles as they are produced. It is believed that consumers will be more satisfied with their car purchases when they know that if something goes wrong with the vehicle, there is a quick and easy way to repair it. While diagnostic codes have not eradicated breakdowns, they sure make repairing them much easier.
