Diagnosis Procedure

Diagnosis Procedure

1. CHECK INPUT 1 - 6 CIRCUIT FOR OPEN

   1. 1. Ignition switch OFF.

      2. Disconnect BCM connector and combination switch connector.

      3. Check continuity between BCM harness connector and combination switch harness connector.

         Combination switch signal	BCM		Combination switch		Continuity
         	Connector	Terminal	Connector	Terminal
         INPUT 1	M83	67	M28	1	Yes
         INPUT 2		68		3
         INPUT 3		69		4
         INPUT 4		70		6
         INPUT 5		71		8
         INPUT 6		72		13

   Is the inspection result normal?

   YES >>

   GO TO 2.

   NO >>

   Repair harness or connectors.

2. CHECK INPUT 1 - 6 CIRCUIT FOR SHORT

   1. Check for continuity between BCM harness connector and ground.

      Combination switch signal	BCM		—	Continuity
      	Connector	Terminal
      INPUT 1	M83	67	Ground	No
      INPUT 2		68
      INPUT 3		69
      INPUT 4		70
      INPUT 5		71
      INPUT 6		72

   Is the inspection result normal?

   YES >>

   GO TO 3.

   NO >>

   Repair harness or connectors.

3. CHECK COMBINATION SWITCH INPUT VOLTAGE

   1. 1. Connect BCM connector.

      2. Ignition switch ON.

      3. Check voltage between BCM harness connector and ground.

         Combination switch signal	(+)		(−)	Voltage (Approx.)
         	BCM
         	Connector	Terminal
         INPUT 1	M83	67	Ground	Refer to Reference Value.
         INPUT 2		68
         INPUT 3		69
         INPUT 4		70
         INPUT 5		71
         INPUT 6		72

   Is the inspection result normal?

   YES >>

   Replace combination switch. Refer to Removal and Installation.

   NO >>

   Replace BCM. Refer to Removal and Installation.
