ECM Mounting Nut: 9.8–11.8 N·m
ECM FAILURE INSPECTION PROCEDURE
- ECM GROUND CIRCUIT TEST: Measure the resistance between the ECM ground and chassis ground using the rear of the ECM harness connector as a checkpoint on the ECM side. If a problem is found, repair it.
Specification: Below 1 Ω
- ECM CONNECTOR TEST: Disconnect the ECM connector and visually inspect the ground terminals on the ECM side and the harness side for bent pins or poor contact pressure. If a problem is found, repair it.
- If no problems are found in steps 1 and 2, the ECM may be faulty. If so, make sure there are no DTCs before replacing the ECM with a new one, then recheck the vehicle. If any DTCs were detected, check them before replacing the ECM.
- RECHECK ORIGINAL ECM: Install the original ECM (possibly faulty) in a vehicle in good condition and inspect the vehicle. If the problem reappears, replace the original ECM with a new ECM. If no problem occurs, the problem is intermittent (refer to "Intermittent Problem Procedure" in Basic Inspection).
