Instrument Cluster Dealer Test Mode
To enter the instrument cluster dealer test mode with the engine off, press and hold the SELECT/RESET button (base cluster) or the message center RESET button (message center cluster). Turn the ignition switch to the ON position and hold the button for approximately 3 to 5 seconds. Release the button and press the reset button one time to display ENGINEERING TEST MODE. Press the reset button once to advance to each stage of the self-test. The information from this mode is displayed in the odometer display. All gauges and lamps will operate normally during this test mode unless otherwise noted.
To exit the instrument cluster self-test mode, turn the ignition to the OFF position.
