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

VOLTAGE BETWEEN DOOR MIRROR LH CONNECTOR AND GROUND REFERENCE

Connector	Terminals (Wire color)		Condition	Voltage (V) (Approx.)
Connector	(+)	(-)	Condition	Voltage (V) (Approx.)
D4	7 (L/Y)	Ground	Mirror motor is operated UP or DOWN	Changes between 3.4 (close to peak) - 0.6 (close to valley)
D4	8 (G)	Ground	Mirror motor is operated LEFT or RIGHT	Changes between 3.4 (close to right edge) - 0.6 (close to left edge)

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 and door mirror LH.
3. Check continuity between automatic drive positioner control unit connector M34 terminals 33, 41 and door mirror LH connector D4 terminals 5, 6.
  33 (W/L) - 5 (W/L) : Continuity should exist .
  
  41 (W/G) - 6 (W/G) : Continuity should exist .
4. Check continuity between automatic drive positioner control unit connector M34 terminals 33, 41 and ground.
  33 (W/L) - Ground : Continuity should not exist .
  
  41 (W/G) - Ground : Continuity should not exist .

OK or NG
- OK : GO TO 4.
- NG : Repair or replace harness.
CHECK HARNESS CONTINUITY 2
1. Check continuity between automatic drive positioner control unit connector M33 terminals 6, 22 and door mirror LH connector D4 terminals 7, 8.
  6 (L/Y) - 7 (L/Y) : Continuity should exist .
  
  22 (G) - 8 (G) : Continuity should exist .
2. Check continuity between automatic drive positioner control unit connector M33 terminals 6, 22 and ground.
  6 (L/Y) - Ground : Continuity should not exist .
  
  22 (G) - Ground : Continuity should not exist .
