Instrument Panel Cluster (IPC) Dealer Test Mode
To enter the IPC dealer test mode, begin with the ignition in the OFF mode. Press and hold the IPC TRIP/RESET button. Place the ignition in the RUN mode and hold the TRIP/RESET button until the display indicates tESt, usually within 3 to 5 seconds. Press the TRIP/RESET button once to advance through each stage of the self-test. To exit the IPC dealer test mode, turn the ignition to the OFF position.
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, DTC xxxx xxxx xxxx may display DTC C0100. Note that there were 12 x's in the display description but only 4 digits in the actual display.
| IPC Display | Description |
|---|---|
| Test | Initial entry display into the dealer test mode. |
| Gauge | Carries out the gauge sweep of all gauges, then displays the present gauge values. |
| LED | Illuminates all the microprocessor controlled lamps and LEDs. |
| Read-Only Memory (ROM) level | Displays the hexadecimal ROM level. For a ROM checksum fault, FAIL displays on the bottom line |
