Diagnosis & Repair

WARNING: This page is about a different car, the 2000 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
  1. Test drive vehicle and check operation of speedometer. If speedometer is not operating correctly, repair speedometer as necessary. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. If speedometer is operating correctly, go to next step.
  2. Access ECM behind passenger's side kick panel. Ensure ignition is off. Disconnect ECM harness connector E7. Check continuity between ground and terminal No. 22 (Violet/White wire) at ECM harness connector E7. See Figure. If continuity exists, locate and repair short to ground in Violet/White wire between instrument cluster and ECM. If continuity does not exist, go to next step.
  3. Turn ignition on. Measure voltage between ground and terminal No. 22 (Violet/White wire) at ECM harness connector E7. If voltage is 9-14 volts, replace ECM. If voltage is not 9-14 volts, repair open in Violet/White wire between instrument cluster and ECM. See WIRING DIAGRAMS article.
