Dealer Test Mode
To enter the Instrument Panel Cluster (IPC) self-diagnostic mode, begin with the ignition in the OFF mode. Press and hold the Right Hand (RH) steering wheel switch OK button (optional Instrument Panel Cluster (IPC)) or the Left Hand (LH) steering wheel switch OK button (base Instrument Panel Cluster (IPC)). Place the ignition in the ON mode and hold the button until the display indicates ENGINEERING TEST MODE, usually within 3 to 5 seconds. Press the up or down arrow buttons to navigate through each of the display windows. To exit the Instrument Panel Cluster (IPC) self-test mode, press and hold the OK button for 3-5 seconds or place the ignition in the OFF mode. The dealer test mode displays multiple items in a viewing window on the Right Hand (RH) side of the Instrument Panel Cluster (IPC). Each button press advances the viewing window to the next set of items.
NOTE:
Some of the displays listed in the table below use xxx's to represent a numeric or alphanumeric 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: DTC HIST CURR xxxxxx x x may display DTC HIST CURR C10000 X. Note that there were 8 x's in the display description but only 7 digits in the actual display.
NOTE:
The table below lists the displays as they appear when navigating using the down arrow button.
