>> Inspection End.

Diagnosis Procedure

INFOID:0000000009567611

Regarding Wiring Diagram information, refer to 

PCS-41, "Wiring Diagram"

.

1.

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

1. Disconnect push-button ignition switch connector.

2. Check voltage between push-button ignition switch connector M25 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

 CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)

Check voltage between IPDM E/R connector E47 terminal 81 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace IPDM E/R. Refer to 

PCS-30, "Removal and Installation"

.

3.
