Diagnosis Procedure

Push-button ignition switch changes the power supply position. BCM maintains the power supply position status. BCM changes the power supply position with the operation of the push-button ignition switch.

1. CHECK PUSH-BUTTON IGNITION SWITCH INPUT SIGNAL 
   1. Ignition switch OFF.
   2. Disconnect push-button ignition switch connector.
   3. Check voltage between push-button ignition switch harness connector and ground.

      (+)		(-)	Voltage (V) (Approx.)
      Push-button ignition switch
      Connector	Terminal
      M101	8	Ground	Battery voltage

   Is the inspection normal?

   YES>>

   GO TO 2.

   NO-1>>

   Check 10 A fuse [No. 10, located in fuse block (J/B)].

   NO-2>>

   Check harness for open or short between push-button ignition switch and fuse.

2. CHECK BCM INPUT 
   1. Connect push-button ignition switch connector.
   2. Disconnect BCM connector.
   3. Check voltage between BCM connector and ground.

      (+)		(-)	Voltage (V) (Approx.)
      BCM
      Connector	Terminal
      M71	73	Ground	Battery voltage
      	91
      	109

   Is the inspection normal?

   YES>>

   Replace BCM. Refer to BCM : Removal and Installation .

   NO>>

   GO TO 3.

3. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT 
   1. Disconnect push-button ignition switch connector.
   2. Check continuity between BCM harness connector and push-button ignition switch harness connector.

      Indicator	BCM		Push-button ignition switch		Continuity
      	Connector	Terminal	Connector	Terminal
      LOCK	M71	91	M101	5	Existed
      ACC		109		6
      ON		73		7

   3. Check continuity between BCM harness connector and ground.

      Indicator	BCM		Ground	Continuity
      	Connector	Terminal
      LOCK	M71	91		Not existed
      ACC		109
      ON		73

   Is the inspection normal?

   YES>>

   Replace push-button ignition switch. Refer to PUSH-BUTTON IGNITION SWITCH : Removal and Installation .

   NO>>

   Repair or replace harness.
