Diagnosis Procedure

INFOID:0000000000927002

1.

CHECK FUSIBLE LINK

Check that the following IPDM E/R fusible link is not blown.

Is the fusible link fusing?

YES

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

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

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

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK GROUND CIRCUIT

1.

Disconnect IPDM E/R connectors.

2.

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

Does continuity exist?

YES

>> INSPECTION END

NO

>> Repair harness or connector.
