2. Check harness for short to ground, between IPDM E/R harness connector and VCM harness connector.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-29, "Removal and Installation"

.

NO

>> Repair or replace error-detected parts.

6.

CHECK CHARGE CONNECTOR LOCK RELAY DRIVE CIRCUIT

1. Disconnect VCM harness connector.

2. Check the continuity between IPDM E/R harness connector and VCM harness connector.

3. Also check harness for short to ground and short to power.
Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Repair or replace error-detected parts.

7.

CHECK VCM GROUND CIRCUIT

Check the continuity between VCM harness connector and ground.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-53, "Intermittent Incident"

.

NO

>> Repair or replace error-detected parts.

8.

CHECK CHARGE CONNECTOR LOCK RELAY OUTPUT CIRCUIT

1. Disconnect EVSE.

2. Disconnect VCM harness connector.

3. Check the continuity between IPDM E/R harness connector and VCM harness connector.

4. Also check harness for short to ground and short to power.
