DTC Diagnosis Procedure

Regarding Wiring Diagram information, refer to appropriate Wiring Diagram .

1. CHECK INPUT 1 - 5 CIRCUIT FOR OPEN 
   1. Turn ignition switch OFF.
   2. Disconnect BCM and combination switch connectors.
   3. Check continuity between BCM connector and combination switch connector.

      Combination switch signal	BCM		Combination switch		Continuity
      	Connector	Terminal	Connector	Terminal
      INPUT 1	M18	36	M28	11	Yes
      INPUT 2		35		9
      INPUT 3		34		7
      INPUT 4		33		10
      INPUT 5		32		13

   Is the inspection result normal?

   YES

   GO TO 2 .

   NO

   Repair harness or connectors.

2. CHECK INPUT 1 - 5 CIRCUIT FOR SHORT 

   Check for continuity between BCM connector and ground.

   Combination switch signal	BCM		Ground	Continuity
   	Connector	Terminal
   INPUT 1	M18	36		No
   INPUT 2		35
   INPUT 3		34
   INPUT 4		33
   INPUT 5		32

   Is the inspection result normal?

   YES

   GO TO 3 .

   NO

   Repair harness or connectors.

3. CHECK BCM OUTPUT VOLTAGE 
   1. Connect BCM connector.
   2. Check voltage between BCM connector and ground.

      BCM signal	Terminals			Voltage
      	(+)		(-)
      	BCM		Ground
      	Connector	Terminal
      OUTPUT 1	M18	36		Refer to Reference Value .
      OUTPUT 2		35
      OUTPUT 3		34
      OUTPUT 4		33
      OUTPUT 5		32

   Is the inspection result normal?

   YES

   Replace combination switch. Refer to Removal and Installation .

   NO

   Replace BCM. Refer to Removal and Installation .
