Diagnosis Procedure

INFOID:0000000009945035

1.

CHECK FUSES AND FUSIBLE LINK

Check that the following IPDM E/R fuses or fusible links are not blown.

Is the fuse fusing?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

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

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair the harness or connector.

3.

CHECK IGNITION POWER SUPPLY CIRCUIT

1.

Turn the ignition switch ON.

2.

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

Is the measurement value normal?

YES

>> GO TO 4.

NO

>> Repair the harness or connector.

4.

CHECK GROUND CIRCUIT

1.

Turn the ignition switch OFF.

2.

Check continuity between IPDM E/R harness connectors and the ground.
