Diagnosis Procedure

INFOID:0000000005276003

Regarding Wiring Diagram information, refer to 

PCS-25, "Wiring Diagram"

.

1.

 CHECK FUSIBLE LINKS

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

Is the fusible link blown?

YES

>> Replace the blown 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 there voltage on all pins?

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?
