Instrument Cluster

  1. Check fuses located in instrument panel fuse block and instrument panel junction block. If more than one gauge is malfunctioning, check common power and ground inputs. See WIRING DIAGRAMS  .
  2. If an indicator does not illuminate, suspect bulb can be tested using scan tool (IPC MISC TESTS) or by checking continuity at instrument cluster connector (instrument cluster side).
  3. Before replacing any components, check for poor terminal contacts at component and associated harness connectors. Check for broken (or partially broken) wire inside of insulation which could cause system failure but pass a continuity/voltage check. Check for proper installation of aftermarket equipment.
  4. Check for Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs). If any PCM DTCs exist, locate and repair problem in PCM system. See TESTS W/CODES article in ENGINE PERFORMANCE section.
