Test E: Warning Indicator Off With Ignition On

  1. Check The Charging System Warning Indicator Operation

    Turn ignition off. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Turn ignition switch to RUN position. Turn on the charging system warning indicator using Active Commands. Is the charging system warning indicator on? If yes, go to next step. If no, see appropriate ANALOG INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.

  2. Check For Correct PCM Operation

    Check for corrosion and pushed-out pins. Connect any disconnected connectors. Make sure all other system connectors are fully seated. Operate the system and verify the concern is still present. Is the concern still present? If yes, install a new PCM. See COMPUTERIZED ENGINE CONTROLS in appropriate REMOVAL & INSTALLATION in ENGINE PERFORMANCE. Repeat the PCM self-test. If no, the system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test.
