PRLog (Press Release) - Dec. 23, 2011 - There are many famous brands of car and truck comes from General Motors, such as Chevrolet, Buick and Cadillac. General Motors cars are equipped with a built-in onboard diagnostics system (also short for OBD) that monitors the car's main operating components. When the engine is malfunction, the diagnostic system creates and sends an error message to turn on the check engine warning light. The light will remain lit until the onboard diagnostics system is reset by an OBD 2 scan tool that connect to a data link connector(which short for DLC) that is included in every car, or just disconnected the battery. The battery method does not always work, relying on the car model and causes other issues such as clearing the radio presets and activating anti-theft features.
You'll Need OBD 2 scan tool for this task.
Find out the data link connector first, below the steering column. The National OBD Clearinghouse website shows the DLC's exact location, often with a photo, for many models cars. The DLC includes two horizontal rows of eight pins each.
Turn the ignition key to the "On" position. The engine does not need to be powered on.
Insert the OBD 2 scanner's connector into the car's DLC and the turn on the OBD scanner. Most scanners can be powered on automatic when it connects to the car.
Follow the instructions that came with the OBD 2 scanner to reset and clear the existing fault codes from the onboard diagnostics system. Different scanners will implement this task in different way, containing pressing an "Erase Codes" button or other similar button going through menu options. Not all scanners have this functionality, so make sure the scanner being used can reset codes.
Unplug the OBD 2 reader from the DLC once the reader has showed that existing error codes have been cleared.
Turn the ignition to "Off," then launch the car to verify the check engine light does not turn on again. If it remains lit, repeat the above processes. If it's still lit after repeating the processed above, this could show a problem with the OBD system. You may ask a mechanic for help. For more information, you can search for online.
