Diagnosis Procedure

INFOID:0000000009579027

Regarding Wiring Diagram information, refer to 

PCS-72, "Wiring Diagram"

.

1.

CHECK IPDM E/R SELF-DIAGNOSTIC RESULT

1. Erase IPDM E/R DTCs.

2. Turn ignition switch OFF.

3. Turn ignition switch ON.

4. Perform Self Diagnostic Result of IPDM E/R with CONSULT.
Are any DTCs detected?

YES

>> Refer to 

PCS-21, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK IGNITION RELAY-1 CONTROL SIGNAL (IPDM E/R)

1. Turn ignition switch OFF.

2. Check voltage between IPDM E/R connector E47 and ground.

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-31, "Removal and Installation"

.

NO

>> GO TO 3.

3.

CHECK IGNITION RELAY-1 CONTROL SIGNAL CIRCUIT (IPDM E/R)

1. Turn ignition switch OFF.

2. Disconnect BCM connector M98 and IPDM E/R connector E47.

3. Check continuity between IPDM E/R connector E47 and ground.

Is the inspection result normal?

YES

>> GO TO 4.
