Diagnosis & Repair Procedure

  1. Ensure ignition is off. Access ECT ECU. See Figure. Backprobing ECT ECU harness connector with ohmmeter, measure resistance between terminal No. S1 and/or S2 and ground. See Figure-Figure . If resistance is 11-15 ohms, replace ECT ECU and retest. If resistance is not within specification, go to next step.
  2. Disconnect solenoid harness connector (next to PNP switch) at transaxle. Check continuity between terminal S1 of transaxle harness connector and corresponding terminal of ECT ECU harness connector. See Fig 1 and Figure-Figure .
  3. Check continuity between terminal S2 of transaxle harness connector and corresponding terminal of ECT ECU harness connector. If continuity exists for both circuits, go to next step. If continuity does not exist for either circuit, inspect and repair circuit(s) as needed.
  4. Measure resistance between transaxle connector terminals S1 and/or S2, and ground. See Fig 1. If resistance is 11-15 ohms, replace solenoid. If resistance is not as specified, replace transaxle sub-harness as needed.
