7.1 Troubleshooting Instrument Cluster and GaugesBegin diagnosing instrument cluster electrical problems by checking the fuses. Make a thorough check in the engine compartment and under the instrument panel for disconnected or damaged wires or connectors. If the fuses, wires, and connectors are intact, then problems are caused by the correct signal not reaching the instrument cluster, or by faulty instrument cluster components. For an additional aid to troubleshooting the instrument cluster, refer to the current flow diagrams at the end of this section for terminal and connector locations. For information on how to use the diagrams, see 3. Troubleshooting. If only one function is affected, the problem is most likely one which affects only that individual circuit. If more than one function of the instrument cluster is affected, it is logical to begin with the instrument cluster's common wiring. Check the main power supply from the ignition switch, the main ground wire, and the voltage stabilizer as described below. |
