YES

>> GO TO 6

NO

>> Repair or replace harness.

4.

 CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM)

1. Disconnect push-button ignition switch.

2. Check voltage between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5

NO

>> Replace BCM. Refer to 

BCS-87, "Removal and Installation"

.

5.

 CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)

1. Disconnect BCM and IPDM E/R.

2. Check continuity between BCM harness connector (A) and

push-button ignition switch harness connector (B).

BCM : Diagnosis Procedure

INFOID:0000000004498310

1.

 CHECK FUSE AND FUSIBLE LINK

Check if the following BCM fuse or fusible link are blown.

Is the fuse or fusible link blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM.

3. Check voltage between BCM harness connector and ground.

Is the measurement normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.

BCM : Special Repair Requirement

INFOID:0000000004498311

agnosis Procedure

INFOID:0000000004498312

1.

 CHECK FUSES AND FUSIBLE LINK

Check that the following IPDM E/R fuses or fusible link are not blown.

Is the fuse blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R.

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

ground.

Is the measurement value normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

Check continuity between IPDM E/R harness connectors and

ground.

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.
