  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 ON-VEHICLE TESTING.
  2. Connect scan tool to Data Link Connector (DLC). See COMPONENT LOCATIONS  . Start engine and allow voltage to stabilize. Using scan tool, observe VOLTS parameter from Instrument Panel Cluster (IPC) data list. If VOLTS parameter is 10.5-16.2 volts, go to next step. If VOLTS parameter is not 10.5-16.2 volts, go to TEST A: CHARGING SYSTEM TEST  under SYSTEM TESTS.
  3. Replace IPC. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. After repairs are made, go to next step.
  4. Using scan tool, clear DTCs. Start engine. If DTC B1513 or DTC B1514 does not reset, system is okay. If DTC B1513 or DTC B1514 resets, go to step  2 .
