Diagnosis Procedure

PUSH-BUTTON IGNITION SWITCH


Description

BCM transmits the change in the power supply position with the push-button ignition switch to IPDM E/R via CAN communication line. IPDM E/R transmits the power supply position status via CAN communication line to BCM.





PUSH-BUTTON IGNITION SWITCH


Diagnosis Procedure

1.CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL 1
1. Turn ignition switch OFF.
2. Disconnect push-button ignition switch connector and IPDM E/R connector.
3. Check voltage between push-button ignition switch harness connector and ground.





Is the inspection result normal?
YES - GO TO 3.
NO - GO TO 2.
2.CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT 1

2. Check continuity between BCM harness connector and push-button ignition switch harness connector.





3. Check continuity between BCM harness connector and ground.





Is the inspection result normal?
YES - Replace BCM. Removal And Installation.
NO - Repair or replace harness.
3.CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL 2
Check voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 4.
4.CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT 2
1. Disconnect BCM connector.
2. Check continuity between IPDM E/R harness connector and push-button ignition switch harness connector.





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





Is the inspection result normal?
YES - Replace IPDM E/R. With I-Key.
NO - Repair or replace harness.
5.CHECK PUSH-BUTTON IGNITION SWITCH GROUND CIRCUIT
Check continuity between push-button ignition switch harness connector and ground.





Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace harness.
