NO >> Check the harness and repair the root cause.
4.CHECK ECM AND IPDM E/R TERMINATION CIRCUIT
1. Remove the ECM and the IPDM E/R.
2. Check the resistance between the ECM terminals.
3. Check the resistance between the IPDM E/R terminals.
Is the measurement value within the specification? YES >> GO TO 5.
NO >> Replace the ECM and/or the IPDM E/R.
5.CHECK SYMPTOM
Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with customer)” are reproduced.
