NOTE:
This DTC may be detected if the above state continues for a long time.
Is the inspection result normal?
YES- Explain the customer that this is the normal operation.
NO- GO TO 2.

2. CHECK 12V BATTERY POWER SUPPLY-I

1.Turn power switch OFF.
2.Check the voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 7.
NO- GO TO 3.

3. CHECK 12V BATTERY POWER SUPPLY-II

1.Disconnect IPDM E/R harness connector (E14).
2.Check the voltage between IPDM E/R connector and ground.





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

4. CHECK IPDM E/R

1.Remove IPDM E/R.
2.Check the continuity between IPDM E/R connector terminals.





Is the inspection result normal?
YES- Check 12V battery power supply circuit.
NO- GO TO 5.

5. CHECK FUSE

1.Pull out #43 fuse.
2.Check the fuse is not fusing.
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.

6. CHECK 12V BATTERY POWER SUPPLY CIRCUIT

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





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

7. DC/DC-J/B OUTPUT POWER CIRCUIT

1.Disconnect DC/DC-J/B terminal (E202).
2.Disconnect F/L-A.
3.Check the continuity between DC/DC-J/B harness terminal and F/L-A terminal.





4.Also check harness for short to ground.
Is the inspection result normal?
YES- GO TO 8.
NO- Repair or replace error-detected parts.

8. CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
