Diagnosis & Repair

  1. Test drive vehicle and check operation of speedometer. If speedometer operates properly, go to next step. If speedometer does not operate properly, repair speedometer as necessary. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. Speedometer may not operate, as input signal from vehicle speed sensor may not be input to instrument cluster.
  2. Remove glove box and passenger's side kick panel (if necessary) for access to ECM with electrical connectors still installed on ECM. See Figure. Using ohmmeter, check for continuity between body ground and terminal No. 22 (Violet/White or White wire) at ECM electrical connector E7. See Figure. This is the SPD terminal on ECM. There are 2 different wiring harnesses used and wire color varies according to wiring harness used. If no continuity exist, go to next step. If continuity exist, repair short to ground in Violet/White or White and electrical connectors between ECM and instrument cluster. See WIRING DIAGRAMS article.
  3. Raise and support vehicle so front wheels may be rotated. Place transaxle in Neutral. Turn ignition on. Using voltmeter, check voltage between body ground and terminal No. 22 (Violet/White or White wire) at ECM electrical connector E7 while slowly rotating front wheel. See Figure. This is the SPD terminal on ECM. Voltage should pulse between 0-5.0 volts. If voltage is within specification, replace ECM. If voltage is not within specification, repair open in Violet/White or White wire and electrical connectors between ECM and instrument cluster. See WIRING DIAGRAMS article.
