Diagnostic Trouble Code Tests and Associated Procedures

Before proceeding to the Symptom Chart:
^ Review equipment level of vehicle.
^ Make note of module and systems with which vehicle is not equipped.
^ Before performing a pinpoint test, make sure DTC being diagnosed is referencing a module or system with which the vehicle is equipped.
^ New Generation STAR (NGS) Tester may produce a network DTC for no communication if the vehicle is not equipped with the suspect module or system.
^ New Generation STAR (NGS) Tester will interpret a not equipped module as a communication failure.
^ If a DTC is retrieved for a not equipped module or system, disregard this DTC.
^ If a not equipped DTC is the only DTC retrieved, the communication system self test should be considered passed.
