Mirror Sensor LH Circuit Check

WARNING: This page is about a different car, the 2004 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

CHECK DOOR MIRROR FUNCTION
Check the following items.

Operation malfunction in memory control

NOTE: If a door mirror face position is set to an implausible angle, the set position may not be reproduced.

OK or NG
1. OK: GO TO 2.
2. NG: Repair the malfunctioning parts, and check the symptom again.

CHECK MIRROR SENSOR CHECK

With CONSULT-II

Check that "ON" is displayed on "MIR/SE LH R-L, MIR/SE LH U-D" in the DATA MONITOR.

Without CONSULT-II

Turn ignition switch ACC.

Check voltage between door mirror (driver side) connector and ground.

VOLTAGE CHECK CHART

Connector	Terminals (Wire color)		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
D2	4 (G)	Ground	When motor is LEFT or RIGHT operation	Changes between 3.4 (close to right edge) - 0.6 (close to left edge)
D2	10 (L/Y)	Ground	When motor is UP or DOWN operation	Changes between 3.4 (close to peak) - 0.6 (close to valley)

OK or NG

OK: Mirror sensor LH is OK.
NG: GO TO 3.

CHECK HARNESS CONTINUITY 1
1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit connector and door mirror (driver side) connector.
3. Check continuity between automatic drive positioner control unit connector M20 terminal 33 (W/L), 41 (Y) and door mirror (driver side) connector D2 terminal 3 (W/L), 9 (Y).
  33 (W/L) - 3 (W/L): Continuity should exist.
  
  41 (Y) - S (Y): Continuity should exist.
4. Check continuity between automatic drive positioner control unit connector M20 terminal 33 (W/L), 41 (Y) and ground.
  33 (W/L) - Ground: Continuity should not exist.
  
  41 (Y) - Ground: Continuity should not exist.

OK or NG
1. OK: GO TO 4.
2. NG: Repair or replace harness between automatic drive positioner control unit and door mirror (driver side).
CHECK HARNESS CONTINUITY 2
1. Check continuity between automatic drive positioner control unit connector M19 terminal 6 (L/Y), 22 (G) and door mirror (driver side) connector D2 terminal 4 (G), 10 (L/Y).
  6 (L/Y) - 10 (L/Y): Continuity should exist.
  
  22 (G) - 4 (G): Continuity should exist.
2. Check continuity between automatic drive positioner control unit connector M19 terminal 6 (L/Y), 22 (G) and ground.
  6 (L/Y) - Ground: Continuity should not exist.
  
  22 (G) - Ground: Continuity should not exist.
