Mirror Sensor LH Circuit Check

WARNING: This page is about a different car, the 2003 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 INSPECTION

With CONSULT-II

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

MONITOR ITEM

Monitor item [OPERATION or UNIT]		Contents
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 displayed.

Without CONSULT-II

Connect automatic drive positioner control unit and door mirror (driver side) connector.
Turn ignition switch ACC.

CHECK HARNESS CONTINUITY 1
1. Disconnect automatic drive positioner control unit connector and door mirror (driver side) connector.
2. 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).
  1. 33 (W/L) - 3 (W/L): Continuity should exist.
  2. 41 (Y) - 9 (Y): Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M20 terminal 33 (W/L), 41 (Y) and ground.
  1. 33 (W/L) - Ground: Continuity should not exist.
  2. 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. Disconnect automatic drive positioner control unit connector and door mirror (driver side) connector.
2. 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).
  1. 6 (L/Y) - 10 (L/Y): Continuity should exist.
  2. 22 (G) - 4 (G): Continuity should exist.
3. Check continuity between automatic drive positioner control unit connector M19 terminal 6 (L/Y), 22 (G) and ground.
  1. 6 (L/Y) - Ground: Continuity should not exist.
  2. 22 (G) - Ground: Continuity should not exist.
OK or NG
1. OK : Replace door mirror (driver side).
2. NG : Repair or replace harness between automatic drive positioner control unit and door mirror (driver side).
