DTC CONFIRMATION PROCEDURE

1.

 PERFORM SELF DIAGNOSTIC RESULT

1. Turn ignition switch to ON, and wait for 1 second or more.

2. Check “Self Diagnosis Result” of “BCM” with CONSULT. 
Is DTC B261A detected?

YES

>> Refer to 

PCS-71, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000011277121

Regarding Wiring Diagram information, refer to 

PCS-56, "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 M17 and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

 CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)

Check voltage between IPDM E/R connector E120 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace IPDM E/R. Refer to 

PCS-40, "Removal and Installation"

.

3.

 CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R)

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R connector E120 and BCM connector M19.

3. Check continuity between IPDM E/R connector E120 and push-button ignition switch connector M17.

 CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM)

Check voltage between BCM connector M19 and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace BCM. Refer to 

PCS-82, "Removal and Installation"

.

5.

 CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)

1. Turn ignition switch OFF.

2. Disconnect BCM connector M19 and IPDM E/R connector E120.

3. Check continuity between BCM connector M19 and push-button ignition switch connector M17.

4. Check continuity between BCM connector M19 and ground.

Is the inspection result normal?

YES

>> Refer to 

GI-44, "Intermittent Incident"

.

NO

>> Repair or replace harness or connectors.
