Diagnosis & Repair

WARNING: This page is about a different car, the 2000 Toyota Corolla. 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 below stereo, behind instrument panel, just in front of center console. Raise and support one front wheel. Turn ignition on. Shift transaxle lever into Neutral. Using DVOM, backprobe ECM harness connector. On models with 4A/T transmission, measure voltage between ground and terminal No. 22 (Violet/White wire) at ECM harness connector E9. See Figure. On models without 4A/T transmission, measure voltage between ground and terminal No. 9 (Violet/White wire) at ECM harness connector E6. See Figure. On all models, observe voltage reading while rotating front wheel. Voltage should pulse between zero volts and 4.5-5.5 volts. If voltage is as specified, replace ECM. If voltage is not as specified, repair open or short in wiring between instrument cluster and ECM. See WIRING DIAGRAMS article.
