Instrument Cluster Self-Diagnostic Mode
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
To enter the instrument cluster self diagnostic mode with the engine off, press and hold the odometer RESET button (base cluster) or the message center RESET button (message center cluster). Turn the ignition switch to the RUN position and hold until the display indicates TEST (base cluster) or TEST (message center cluster) usually within 3 to 5 seconds. Press the reset button once to advance through each stage of the self-test.
To exit the instrument cluster self-test mode, turn the ignition to the OFF position. If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART to continue diagnostics.
