To enter the instrument cluster self-diagnostic mode with the engine off, simultaneously press and hold the message center reset and setup buttons. Turn the ignition switch to the RUN position and hold until the display indicates TEST usually within three to five seconds. Press the reset button once to advance to 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, proceed to the Symptom Chart to continue diagnostics.
