Entering Self-Diagnostics

  1. Turn ignition on. Simultaneously push OFF and WARMER buttons on Climate Control Center (CCC). Continue pushing OFF and WARMER buttons until segment check appears (about 3 seconds) on Instrument Panel Control (IPC).
    NOTE: Failure of any segment to glow may result in inaccurate test results. Replace any inoperative segment display before proceeding with self-diagnostic process.
  2. When segment check appears (all segments glow), system has entered self-diagnostic mode. Release both buttons. Driver Information Center (DIC) will display diagnostic codes. Diagnostic code level displays PCM codes first, followed by IPC, ACP, SIR, TCS and RSS codes (if so prompted).
  3. To proceed to desired level, press and release CCC HI (fan up) button for "yes" or LO (fan down) button for "no". Depress LO button to go to next test level (i.e., IPC?, ACP?, SIR?, TCS? or RSS?) or depress OFF button to return to next selection in previous test level.
  4. To exit diagnostics, press AUTO or DEFOG button on IPC. System will go back to normal vehicle operation.
