Diagnosis & Repair

  1. Test drive vehicle and check operation of speedometer. If speedometer is not functioning correctly, see INSTRUMENT PANEL article in ACCESSORIES/SAFETY EQUIPMENT section. If speedometer is functioning correctly, go to next step.
  2. Access ECM behind bottom center of instrument panel, in front of console. Ensure ignition is off. Shift gear selector to Neutral. Lift and support front of vehicle. Turn ignition on. Using DVOM, measure voltage between ground and terminal No. 9 (Violet/White wire) at ECM E6 connector, while rotating front wheel. See Figure.
  3. As front wheel is rotated, voltage should pulse between zero and 5-6 volts. If voltage is as specified, replace ECM. If voltage is not as specified, check Violet/White wire between instrument cluster and ECM. See appropriate wiring diagram in WIRING DIAGRAMS article. Repair wiring as necessary.
