Test Q: Trip Distance Does Not Accumulate

  1. Turn ignition off. Disconnect message center switch module connector C264. See Figure . Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Disconnect instrument cluster connector C272. See Figure . Measure resistance of Red/Blue wire between message center control module connector C264 terminal No. 8 and instrument cluster connector C272 terminal No. 13. Resistance should be less than 5 ohms. Measure resistance between ground and message center switch module connector C264 terminal No. 8 (Red/Blue wire). Resistance should be more than 10,000 ohms. If resistances are as specified, go to next step. If resistances are not as specified, repair Red/Blue wire.
  2. Leave ignition off and instrument cluster connector C272 disconnected. Reconnect message center control module connector C264. Turn ignition on. Press OD/TRIP switch (located on message center). Measure voltage between ground and instrument cluster connector C272 terminal No. 13 (Red/Blue wire). If voltage is more than 10 volts, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. If voltage is less than 10 volts, replace message center control module.
