Instrument Cluster Self-Diagnostic Mode
To enter the instrument cluster self diagnostic mode with the engine off, depress and hold the odometer reset button. Turn the ignition switch to the RUN position and hold until the gauges sweep (within five to eight seconds). Depress the reset button once to advance to each stage of the self-test.
Turn the ignition to the OFF position to exit the instrument cluster self-diagnostic mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
