Diagnosis Procedure

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.

   (+)		(-)	Voltage (V) (Approx.)
   Push-button ignition switch
   Connector	Terminal
   M50	4	Ground	Battery voltage

   Is the inspection result normal? 

   YES: GO TO  3.

   NO: GO TO 2.

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