Test D: Warning Indicator Off With Ignition On

  1. Connect NGS tester. Turn ignition on and perform PCM self-test. If any Diagnostic Trouble Code (DTC)s are retrieved, see POWERTRAIN CONTROL MODULE (PCM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX  table. If no DTCs are retrieved, go to next step.
  2. Turn ignition off. Disconnect NGS tester and generator 3-pin connector. Turn ignition on. Connect a fused (15-amp) jumper wire between generator 3-pin Gray/Red wire terminal and ground. If warning indicator illuminates, replace generator. See GENERATOR  under REMOVAL & INSTALLATION. If warning indicator does not illuminate, go to next step.
  3. Disconnect PCM connector C175c. Inspect connector for pushed out pins, corrosion or bent terminals. Repair as necessary. If connector is okay, reconnect and retest system operation. If fault is still present, replace PCM. Clear DTCs and repeat PCM self-test. If fault is still not present, system is operating correctly at this time.
