2.Check "SELF-DIAG RESULTS" of "CHARGER".
Is DTC detected?
YES- Proceed to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK FUSE

1.Turn power switch OFF.
2.Pull out #74 fuse and check that the fuse is not fusing.
Is the fuse fusing?
YES- Replace the fuse after repairing the applicable circuit.
NO- GO TO 2.

2. CHECK NORMAL CHARGE RELAY DRIVE VOLTAGE-I

1.Insert the fuse which pulled out.
2.Turn power switch ON.
3.Check the voltage between on-board charger harness connector and ground.





Is the inspection result normal?
YES- GO TO 8.
NO - GO TO 3.

3. CHECK NORMAL CHARGE RELAY DRIVE VOLTAGE-II

1.Turn power switch OFF.
2.Disconnect DC/DC junction box harness connector.
3.Turn power switch ON.
4.Check the voltage between DC/DC junction box harness connector and ground.





Is the inspection result normal?
YES- GO TO 6.
NO- GO TO 4.

4. CHECK NORMAL CHARGE RELAY CIRCUIT

Check normal charge relay circuit. Refer to "Diagnosis Procedure" M/C Relay.
Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace error-detected parts.

5. CHECK NORMAL CHARGE RELAY DRIVE CIRCUIT

1.Check the continuity between DC/DC junction box harness connector and M/C relay harness connector.





2.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO- Repair or replace error-detected parts.

6. CHECK NORMAL CHARGE RELAY DRIVE CIRCUIT

1.Check the continuity between DC/DC junction box harness connector and on-board charger harness connector.





2.Also check harness for short to ground.
Is the inspection result normal?
YES- GO TO 7.
NO- Repair or replace error-detected parts.

7. CHECK NORMAL CHARGE RELAY

Check the resistance between DC/DC junction box connector terminals.





Is the inspection result normal?
YES- Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO- Replace DC/DC junction box. Refer to "Exploded View" Exploded View.

8. CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
Is the inspection result normal?
YES- Replace on-board charger. Refer to "Removal and Installation" Removal And Installation.
NO- Repair or replace error-detected parts.
