Diagnosis Procedure
Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".
- CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (PUSH-BUTTON IGNITION SWITCH)
- Turn ignition switch OFF.
- Disconnect push-button ignition switch connector and IPDM E/R connector E39.
- Check voltage between push-button ignition switch connector M25 and ground.
Push-button ignition switch Ground Voltage (Approx.) Connector Terminal M25 8 - Battery voltage Is the inspection result normal?
YES: GO TO 3.
NO: GO TO 2.
- CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
- Disconnect BCM connector M83.
- Check continuity between BCM connector M83 and push-button ignition switch connector M25.
BCM Push-button ignition switch Continuity Connector Terminal Connector Terminal M83 55 M25 8 Yes - Check continuity between BCM connector M83 and ground.
BCM Ground Continuity Connector Terminal M83 55 - No Is the inspection result normal?
YES: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".
NO: Repair or replace harness or connectors.
