Instrument Cluster Method

WARNING: This page is about a different car, the 2002 Dodge Ram Wagon, 2002 Dodge Ram Van, 2001 Dodge Ram Wagon, and 2001 Dodge Ram Van. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off, press and hold trip odometer RESET button while turning ignition on. Continue to hold RESET button until odometer window displays CHEC (about 10 seconds). Release RESET button. If faults exists, system will display Diagnostic Trouble Codes (DTC). See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table.
  2. If no DTCs appear, cluster will start a walking segment test. First, all segments will be illuminated, then each segment in sequence. If any segment does not illuminate, repeat test to confirm and replace EMIC. When walking segment test is complete, bulb check will start.
  3. If any bulb does not light, remove EMIC. See ELECTRO-MECHANICAL INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Check bulb and bulb holder. Ensure bulb holder is properly installed in cluster. If bulb and bulb holder are okay, replace EMIC. If LED does not light, replace EMIC. When bulb check is complete, gauge actuator test will start.
  4. Each gauge needle should stop at 3 calibration points, then return to relaxed position. See INSTRUMENT CLUSTER CALIBRATION POINTS  table. If any gauge does not perform as specified, remove EMIC. See ELECTRO-MECHANICAL INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Inspect all connections between printed circuit board and gauge terminals, repair as necessary. If connections are okay, replace EMIC. Instrument cluster will automatically exit self-diagnostics when test is complete. If no DTCs exist, repair by performing appropriate symptom test(s) under SYSTEM TESTS  . See SYMPTOM IDENTIFICATION  table.
