  1. Perform ON-BOARD DIAGNOSTIC II (OBD-II) system check. See ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK in SELF-DIAGNOSTICS - INTRODUCTION article. After performing OBD-II system check, go to next step.
  2. Attempt to start engine. If engine starts, go to next step. If engine does not start, go to step  6.
  3. Check for blown METER fuse (10-amp). If fuse is okay, go to next step. If fuse is blown, go to step  16.
  4. Turn ignition on. With test light connected to ground, probe ignition feed circuit at instrument cluster harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step  13.
  5. Turn ignition off. Disconnect PCM harness connectors. Connect fused jumper wire between ground and RPL driver circuit at PCM harness connector. Turn ignition on. If RPL turns on, go to step  10. If RPL does not turn on, go to step  11.
  6. Check for blown ENGINE (15-amp) or PCM (15-amp) fuses. If either fuse is blown, go to next step. If neither fuse is blown, go to step  15.
  7. Turn ignition off. Disconnect PCM. Turn ignition on. With test light connected to ground, probe ignition feed circuit at PCM harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step  12.
  8. Probe battery feed circuit at PCM harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step  14.
