Diagnosis Procedure

INFOID:0000000006158389

Regarding Wiring Diagram information, refer to

PCS-23, "Wiring Diagram"

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.

>> GO TO 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

>> Repair or replace harness.

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.

>> Repair or replace harness.

Terminal No.
