Instrument Cluster (IC) Dealer Test Mode

NOTE: The displays listed in the table below use xxx's to represent a numeric or alpha-numeric value. The value may display the same amount of characters represented by the xxx's or there may be more/less depending on the type of display. For example: xxx.x MPH (base cluster) or VEHICLE SPD (message center cluster) may display 45 MPH or VEHICLE SPD 45 MPH. Note that there were 4 x's in the display description but only 2 digits in the actual display.

To enter the IC dealer test 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 ENGINEERING TEST MODE usually within 5-6 seconds. Press the reset button once to advance to each stage of the self-test.

To exit the IC dealer test mode, press and hold the odometer reset button (base cluster) or the message center RESET button (message center cluster) for approximately 5-8 seconds or turn the ignition to the OFF position.
