M23 (B) terminal 9.





3. Check continuity between BCM harness connector M19 (A) terminal 87 and ground.





Is the inspection result normal?
YES - GO TO 4
NO - Repair harness or connector.
4.CHECK ECVT DEVICE CIRCUIT (IPDM E/R)
1. Disconnect BCM harness connector.





2. Check continuity between ECVT device (detention switch) harness connector M23 (A) terminal 9 and IPDM E/R harness connector E17 (B) terminal 43.





3. Check continuity between ECVT device (detention switch) harness connector M23 (A) terminal 9 and ground.





Is the inspection result normal?
YES - GO TO 5
NO - Repair harness or connector.
5.CHECK ECVT DEVICE
Refer to "Component Inspection".
Is the inspection result normal?
YES - GO TO 6
NO - Replace ECVT device. Refer to Removal And Installation.
6.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
- Inspection End.




Component Inspection
