Multiple/Individual Instrument Cluster Gauges Inoperative

Test speedometer, tachometer and other gauges for malfunction using the following:

  1. First perform cluster self-diagnostics. See SELF-DIAGNOSTICS . If there is a response, watch the effected gauge(s) for operation. Replace cluster as necessary. If there is no response to the cluster self-diagnostics, go to next step.
  2. Remove the cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
  3. Check for ignition voltage at pin 14 of the 26-way cluster wire harness connector. See Fig 1. Check for battery voltage at pin 4 of the 26-way connector. If no voltage, repair as necessary.
  4. Check pin 1 of the 26-way connector for continuity to ground. If no ground, repair as necessary.
  5. If the voltage and ground are OK, and the pins or the connectors are not distorted, replace the instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
