OBD-II code readers could diagnose problems with your vehicle. All vehicles manufactured from 1996 onward are equipped with On-Board Diagnostic II computers. This computer detects error codes and displays warning and service lights on the instrument panel alerting you to have your vehicle checked out and repaired by a mechanic. The codes can be read by an OBD-II code reader and later erased, thus resetting the computer and shutting off the warning and service lights. These code readers are also called scanners and can be purchased from us.

4.Unplug the scanner and have the vehicle serviced or repaired.
