1.CHECK BCM OUTPUT

1. Turn ignition switch OFF.
2. Disconnect push-button ignition switch connector and IPDM E/R connector.
3. Check voltage between IPDM E/R harness connector and ground.

   (+) | (–) | Voltage (V) (Approx.)
   IPDM E/R
   Connector | Terminal
   E5 | 28 | Ground | Battery voltage

Is the inspection result normal?
YES>>Replace IPDM E/R. Refer to Removal and Installation.
NO>>GO TO 2.
2.CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT

1. Disconnect BCM connector.
2. Check continuity between BCM harness connector and IPDM E/R harness connector.

   BCM | IPDM E/R | Continuity
   Connector | Terminal | Connector | Terminal
   M122 | 89 | E5 | 28 | Existed

3. Check continuity between BCM harness connector and ground.

   BCM | Ground | Continuity
   Connector | Terminal
   M122 | 89 | Not existed

Is the inspection result normal?
YES>>Replace BCM. Refer to Removal and Installation.
NO>>Repair or replace harness.
