Dealer Test Mode

NOTE: The table lists the displays as they appear when navigating using the down arrow button.
NOTE: If popup warnings exist, the dealer test mode cannot be entered. All message center warnings and popup displays need to be addressed to enter the dealer test mode.

To enter the IPC engineering test mode or dealer test mode, begin with the ignition OFF. Close all doors and luggage compartment then press and hold the RH steering wheel switch OK button. Place the ignition ON and continue to hold the button for 5-8 seconds until an ET RTT appears at the bottom of the main message center display (analog IPC) or in the rotating RTT display (lower RH side) (digital IPC). Press the up or down arrow buttons to navigate through each of the display windows. To exit the IPC dealer test mode, press and hold the OK button for 5-8 seconds or place the ignition in OFF. Each down arrow button press advances the viewing window to the next set of items.
