Speedometer/Odometer Inoperative

  1. Turn ignition switch to OFF position. Disconnect VSS connector. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Check resistance between cluster connector C2, pins No. 6 (White/Blue wire) and No. 1 (White/Blue Wire) of VSS harness connector. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair circuit No. 8 (White/Blue wire) for open.
  2. Measure resistance between cluster connector C1, pin No. 13 (Black wire) and ground. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair circuit No. 31 (Black wire) for open and retest circuit.
  3. Turn ignition switch to ON position. Check for voltage between cluster connector C1, pin No. 7 (Orange wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, repair circuit No. 29 (Orange wire) for open and retest.
  4. Turn ignition switch to OFF position. Check continuity between cluster connector C2, pin No. 6 (White/Blue wire) and center pin of speedometer printed circuit. If there is 5 ohms or less resistance, go to next step. If resistance is more than 5 ohms, replace printed circuit board and retest. See PRINTED CIRCUIT  under REMOVAL & INSTALLATION.
  5. Turn ignition switch to OFF position. Check resistance between cluster connector C1, pin No. 7 (Orange wire) and right head pin of speedometer printed circuit. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, replace printed circuit board and retest system.
  6. Check resistance from cluster connector C1, pin No. 13 (Black wire) and left pin of speedometer printed circuit. If resistance is 5 ohms or less, replace speedometer and retest system. If resistance is more than 5 ohms, replace printed circuit board and retest system.
