Nissan Rogue (T33) 2021-Present Service Manual: Dtc/circuit Diagnosis :: Combination Switch Output Circuit

Diagnosis Procedure

CHECK OUTPUT CIRCUIT

1. Ignition switch ON.

2. Turn ON any switch in the system that is malfunctioning.

3. Check duty ratios between BCM harness connector and ground by using an oscilloscope.

   With type A meter

   System	+		−	Voltage (Approx.)
   	BCM
   	Connector	Terminal
   Output 1	M58	75	Ground	Refer to Reference Value.
   Output 2		76
   Output 3		72
   Output 4		71
   Output 5		73
   Output 6		74

   With type B meter

   System	+		−	Voltage (Approx.)
   	BCM
   	Connector	Terminal
   Output 1	M19	48	Ground	Refer to Reference Value.
   Output 2		49
   Output 3		53
   Output 4		52
   Output 5		50
   Output 6		51

Is the inspection result normal?

Check intermittent incident. Refer to Intermittent Incident.

Fixed to 0 V: GO TO 2.

Fixed to 9 – 16 V: Replace BCM. Refer to Removal and Installation.

CHECK OUTPUT CIRCUIT FOR OPEN

1. Ignition switch OFF.

2. Disconnect BCM connector.

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

   Output 1	M58	75	M28	7	Yes
   Output 2		76		15
   Output 3		72		10
   Output 4		71		5
   Output 5		73		2
   Output 6		74		12

   With type B meter

   System	BCM		Combination switch		Continuity
   	Connector	Terminal	Connector	Terminal
   Output 1	M19	48	M28	7	Yes
   Output 2		49		15
   Output 3		53		10
   Output 4		52		5
   Output 5		50		2
   Output 6		51		12

Is the inspection result normal?

GO TO 3.

Repair harnesses or connector.

CHECK OUTPUT CIRCUIT FOR SHORT

Check for continuity between BCM harness connector and ground.

Is the inspection result normal?

Replace combination switch. Refer to Removal and Installation.

Repair harnesses or connector.
