Mirror Sensor LH Circuit Inspection

WARNING: This page is about a different car, the 2008 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

CHECK MIRROR SENSOR LH INPUT/OUTPUT SIGNAL

With CONSULT-III

Check operation with "MIR/SEN LH R-L, MIR/SEN LH U-D" on the DATA MONITOR to make sure pulse changes.

MIRROR SENSOR LH INPUT/OUTPUT SIGNAL

Monitor item [OPERATION or UNIT]
MIR/SEN LH R-L	"V"	Voltage output from LH door mirror sensor (LH/RH) is displayed.
MIR/SEN LH U-D	"V"	Voltage output from LH door mirror sensor (UP/DOWN) is displaced.

Without CONSULT-III

Turn ignition switch to ACC.

Check voltage between door mirror LH connector and ground.

DOOR MIRROR LH CONNECTOR AND GROUND

Connector	Terminals		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
D4	5	Ground	When motor is UP or DOWN operation	Changes between 3.4 - 0.6
D4	11	Ground	When motor is LEFT or RIGHT operation	Changes between 3.4 - 0.6

OK or NG

OK: Mirror sensor LH circuit is OK.

NG: GO TO 2.

CHECK HARNESS CONTINUITY 1
1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit and door mirror LH.
3. Check continuity between automatic drive positioner control unit connector M42 terminals 33, 41 and door mirror LH connector D4 terminals 4,12.
  33 - 4: Continuity should exist.
  
  41 - 12: Continuity should exist.
4. Check continuity between driver seat control unit connector M42 terminals 33, 41 and ground.
  33 - Ground: Continuity should not exist.
  
  41 - Ground: Continuity should not exist.

OK or NG

OK: GO TO 3.

NG: Repair or replace harness.
CHECK HARNESS CONTINUITY 2
1. Check continuity between automatic drive positioner control unit connector M41 terminals 6, 22 and door mirror LH connector D4 terminals 5,11.
  6 - 5: Continuity should exist.
  
  22 - 11: Continuity should exist.
2. Check continuity between driver seat control unit connector M41 terminals 6, 22 and ground.
  6 - Ground: Continuity should not exist.
  
  22 - Ground: Continuity should not exist.
