Diagnosis Procedure

INFOID:0000000009266489

Regarding Wiring Diagram information, refer to 

PCS-68, "Wiring Diagram"

.

1.

 CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (PUSH-BUTTON IGNITION SWITCH)

1. Turn ignition switch OFF.

2. Disconnect push-button ignition switch connector and IPDM E/R connector E47.

3. Check voltage between push-button ignition switch connector M25 terminal 8 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

 CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)

1. Disconnect BCM connector M98.

2. Check continuity between BCM connector M98 terminal 76 and push-button ignition switch connector

M25 terminal 8.

3. Check continuity between BCM connector M98 terminal 76 and ground.

Is the inspection result normal?

YES

>> Replace BCM. Refer to 

BCS-69, "Removal and Installation"

.

NO

>> Repair or replace harness or connectors.

3.
