IPC Segment Check

  1. Turn ignition switch to ON position. On non-CRT equipped vehicles, simultaneously push OFF and WARM buttons on Electronic Climate Control Panel (ECCP). On CRT equipped vehicles, simultaneously push OFF button and touch WARM key on CRT monitor control panel.
  2. On non-CRT and CRT equipped vehicles, continue to depress OFF and WARM buttons/keys until all segments and bulbs of IPC, Driver Information Center (DIC) panel and ECCP glow. See Figure and Figure . When all segments are lit, system has entered self-diagnostic mode. Release OFF and WARM buttons/keys.
  3. Illuminating segments of IPC, DIC and ECCP ensures all display segments are working properly. If all segments glow, proceed to DISPLAYING TROUBLE CODES. Failure of any segment to glow may result in inaccurate test results. All segments of display must be made to operate before proceeding with self-diagnostic procedures.
  4. Partial segment check is possible by depressing TEST button on IPC when transaxle is in Park or Neutral. Holding button depressed will light all vacuum fluorescent displays and all telltales on IPC in order to check for faulty bulbs or light panels.
