These car code readers turn out to be really a really handy tool when trying to figure out what's wrong with your Chevrolet vehicle. But if it is your first time using these reliable gadgets, it would be a little tricky for you understand their functionality. Before getting into the procedure of how to use a car code reader it is better if you are enlightened a little for about these car code readers. had the requirement of having OBD system within them. OBD stands for On-Board Diagnostic and the vehicles range from OBD I, and OBD II depending on their year of manufacturing. Thus the car code readers that are available in the market, some are compatible with only OBD I Chevrolet vehicles while the models with a higher quality are compliant with both OBD I and OBD II vehicles.
Now getting to the point on how to use a car code reader, the following simple procedure should help you understand the gadget's functionally and would make it easier for you to figure out how it works. First of all you need to make sure whether your car even has an OBD system or not, which most Chevrolet vehicles after 1996 do unless your Chevrolet car is an older model, because this device would render useless otherwise. Upon confirmation that your car is indeed in the OBD category, you then to find the Chevrolet car's Diagnostic Line Connector or DLC in short which can usually be found within close proximity of the steering wheel or nearer to the pedals, but it would always be wiser to consult the car manual. Once you've found the DLC, you need to hook up the plug of the code reader to the connector.
Once the reader is properly plugged, you now need to give the Chevrolet car electrical power by bringing the ignition key to "on" (be sure not to turn on the engine). Once this is done the dashboard components of your car should light up and the code reader will start functioning. Now all you need to do is, wait for the reader to diagnose the problem providing you with the code on its screen. While your Chevrolet car would be rid of the "Check Your Engine Light" you can tally the code with either the manual that came with the reader or using the software CD to hook up the device to a PC. Lastly you must also realize that with such numerous brands in the market the functionality varies from model to model so you can opt for reading its manual first.
There is no doubt that the modern Chevrolet vehicles of today are electronically controlled and therefore using a handy tool like car code readers is an ideal option.
