Diagnosis Procedure

INFOID:0000000001697594

1.

 CHECK FUSES AND FUSIBLE LINK

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

Is the fuse blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK BATTERY POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R.

3.

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

Is the measurement value normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

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

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.
