B261A PUSH-BUTTON IGNITION SWITCH

Is the inspection result normal?

YES

>> Replace BCM. Refer to 

BCS-94, "Removal and Installation"

.

NO

>> Repair or replace harness.

3.

CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)

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

Is the inspection result normal?

YES

>> Replace IPDM E/R.

NO

>> GO TO 4.

4.

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

1. Disconnect BCM connector.

2. Check continuity between IPDM E/R harness connector and push-button ignition switch harness connec-

tor.

3. Check continuity between push-button ignition switch harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace harness.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1. Turn ignition switch ON under the following conditions, and wait for 2 seconds or more.

CVT models

-

Selector lever is in the P or N position

-

Do not depress brake pedal

M/T models

-

Do not depress clutch pedal

Is DTC detected?

YES

>> Go to 

PCS-73, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012197211

1.

CHECK IPDM E/R SELF-DIAGNOSTIC RESULT

1. Turn ignition switch ON.

2. Erase the DTC of IPDM E/R.

3. Turn ignition switch OFF.

4. Turn ignition switch ON and check the DTC again.
Is DTC detected?

YES

>> Repair or replace the malfunctioning part. Refer to 

PCS-24, "DTC Index"

.

NO

>> GO TO 2.

2.

CHECK IGNITION RELAY (IPDM E/R) CONTROL SIGNAL

Check voltage between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace BCM. Refer to 

BCS-94, "Removal and Installation"

.

3.

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

1. Turn ignition switch OFF.

2. Disconnect BCM and IPDM connectors.

3. Check continuity between BCM harness connector and IPDM E/R harness connector.

DTC No.
