Instrument Panel Cluster (IPC) Dealer Test Mode
To enter the IPC self-diagnostic mode for vehicles without Intelligent Access (IA), begin with the ignition key in the OFF position. Press and hold the message center RESET button. Turn the key to the RUN position and hold the RESET button until the message center displays ENGINEERING TEST MODE, usually within 3 to 5 seconds. Press the RESET button once to advance through each stage of the self-test. To exit the IPC self-test mode, turn the ignition to the OFF position.
To enter the IPC self-diagnostic mode for vehicles with IA, begin with the ignition in the OFF mode. Press and hold the message center RESET button. Press and hold the START button for 2 seconds to enter the ignition RUN mode and continue to hold the RESET button until the message center displays ENGINEERING TEST MODE, usually within 3 to 5 seconds. Press the RESET button once to advance through each stage of the self-test. To exit the IPC self-test mode, place the ignition in the OFF mode.
NOTE:
If the message center detects a fault condition that it is reporting out on such as door ajar, the dealer test mode session cannot be entered until the fault condition has been corrected and the message removed. If the dealer test mode session is interrupted by a fault condition display (such as door ajar), the session can be resumed by pressing the RESET button.
NOTE:
Some of 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: VEHICLE SPEED xxxx.x MPH may display VEHICLE SPEED 25 MPH. Note that there were 4 x's in the display description but only 2 digits in the actual display.
