Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK DOOR MIRROR MOTOR INPUT SIGNAL 
   1. Turn ignition switch ON.
   2. Check voltage between door mirror connector and ground.

      Terminals			Door mirror remote control switch condition	Voltage (V) (Approx.)
      (+)		(-)
      Door mirror connector	Terminal
      D4 (LH) D107 (RH)	1	Ground	UP	Battery voltage
      			Other than above	0
      	2		LEFT	Battery voltage
      			Other than above	0
      	3		DOWN/RIGHT	Battery voltage
      			Other than above	0

      Is the inspection result normal? 

      YES: Refer to "COMPONENT INSPECTION ".

      NO: GO TO 2

2. CHECK HARNESS CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect automatic drive positioner control unit and door mirror.
   3. Check continuity between automatic drive positioner control unit connector and door mirror connector.
