Diagnosis & Repair

WARNING: This page is about a different car, the 2002 Toyota Highlander. 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 operating correctly, go to next step. If speedometer is not operating correctly, repair speedometer as necessary. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
  2. Access ECM behind glove box. See Figure. Ensure ignition is off. Disconnect ECM harness connector E6. See Figure. Measure resistance between ground and terminal No. 22 (White/Red wire) at ECM harness connector E6. If resistance is more than one megohm, go to next step. If resistance is one megohm or less, locate and repair short to ground in wiring between ECM and instrument cluster. See WIRING DIAGRAMS article.
  3. Turn ignition on. Measure voltage between ground and terminal No. 22 (White/Red wire) at ECM harness connector E6. If voltage is 9-14 volts, replace ECM. If voltage is not 9-14 volts, repair open in wiring between instrument cluster and ECM. See WIRING DIAGRAMS article.
