DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

- Turn power switch OFF and wait at least 20 seconds.
- Make sure that 12V battery voltage is 11 V or more.
- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT
1.Set the vehicle to READY and wait at least 5 seconds.
2.Check DTC.
Is DTC detected?
YES- Proceed to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK FUSE

1.Turn power switch OFF.
2.Pull out #64 fuse.
3.Make sure that fuse is not fusing.
Is the inspection result normal?
YES- GO TO 2.
NO- Replace the fuse after repairing the applicable circuit.

2. CHECK 12V BATTERY POWER SUPPLY

1.Insert the fuse which pulled out.
2.Disconnect IPDM E/R harness connector (E2).
3.Check the voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 3.
NO- Check 12V battery power supply routing circuit.

3. CHECK F/S RELAY OUTPUT VOLTAGE

1.Reconnect IPDM E/R harness connector (E2).
2.Turn power switch ON.
3.Check the voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 9.
NO- GO TO 4.

4. CHECK F/S RELAY DRIVE CIRCUIT VOLTAGE-I

Check the voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 7.
NO- GO TO 5.

5. CHECK F/S RELAY DRIVE CIRCUIT

1.Turn power switch OFF.
2.Disconnect VCM harness connector and IPDM E/R harness connector.
3.Check continuity between VCM harness connector and IPDM E/R harness connector.





Is inspection result normal?
YES- GO TO 6.
NO- Repair or replace error-detected parts.

6. CHECK VCM GROUND CIRCUIT

Check the continuity between VCM harness connector and ground.





Is inspection result normal?
YES- Replace VCM. Refer to "Removal and Installation" Removal And Installation.
NO- Repair or replace error-detected parts.

7. CHECK F/S RELAY DRIVE CIRCUIT VOLTAGE-II

1.Turn power switch OFF.
2.Disconnect IPDM E/R harness connector (E15).
3.Check the voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 8.
NO- Replace IPDM E/R. Refer to "Removal and Installation" Removal And Installation.

8. CHECK F/S RELAY OUTPUT CIRCUIT-I

1.Disconnect VCM harness connector.
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 "Removal and Installation" Removal And Installation.
NO- Repair or replace error-detected parts.

9. CHECK F/S RELAY OUTPUT CIRCUIT-II

1.Turn power switch OFF.
2.Disconnect VCM harness connector and IPDM E/R harness connector.
3.Check continuity between VCM harness connector and IPDM E/R harness connector.





Is inspection result normal?
YES- Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO- Repair or replace error-detected parts.
