Test B: Charge Indicator Light Always On

  1. If engine electrical diagnostic system check was performed, go to next step. If engine electrical diagnostic system check was not performed, go to ENGINE ELECTRICAL DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  2. Start engine. If battery charge indicator remains illuminated after 5 second bulb check, go to next step. If battery charge indicator does not remain illuminated after 5 second bulb check, problem may be intermittent. Check wiring and connections, and see PRELIMINARY INSPECTION  under TROUBLE SHOOTING.
  3. Connect scan tool to Data Link Connector (DLC). Using scan tool, observe BATTERY VOLTAGE parameter from Instrument Panel Cluster (IPC) data list. If voltage measures 10.5-15.5 volts, go to next step. If voltage does not measure 10.5-15.5 volts, go to TEST A: CHARGING SYSTEM TEST .
  4. Replace IPC. See INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. After repairs are made, go to next step.
  5. Operate system to verify repair. If condition was corrected, system is okay. If condition was not corrected, go to step  2.
