Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM - JAPAN PRODUCTION , or WIRING DIAGRAM - USA PRODUCTION .

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

      (+)		(-)	Door mirror remote control switch condition	Voltage (V) (Approx.)
      Door mirror
      Connector	Terminal
      D16 (LH) D106 (RH)	12	Ground	UP	Battery voltage
      			Other than above	0
      	5		LEFT	Battery voltage
      			Other than above	0
      	4		DOWN / RIGHT	Battery voltage
      			Other than above	0

   Is the inspection result normal?

   YES 

   Refer to COMPONENT INSPECTION .

   NO 

   GO TO STEP 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.

      Connector	Terminal	Connector	Terminal
      M99	10	D106	12	Yes
      	11		5
      	22		4

   4. Check continuity between automatic drive positioner control unit connector and ground.

      Door mirror LH

      Automatic drive positioner control unit		Ground	Continuity
      Connector	Terminal
      M99	12		No
      	23
      	24

      Door mirror RH

      Automatic drive positioner control unit		Ground	Continuity
      Connector	Terminal
      M99	10		No
      	11
      	22

   Is the inspection result normal?

   YES 

   GO TO STEP 3. 

   NO 

   Repair or replace harness.

3. CHECK AUTOMATIC DRIVE POSITIONER CONTROL UNIT OUTPUT SIGNAL
   
   
   1. Connect automatic drive positioner control unit.
   2. Turn ignition switch ON.
   3. Check voltage between automatic drive positioner control unit connector and ground.

      Door mirror LH

      (+)		(-)	Mirror switch condition	Voltage (V) (Approx.)
      Automatic drive positioner control unit
      Connector	Terminal
      M99	12	Ground	DOWN / RIGHT	Battery voltage
      			Other than above	0
      	23		UP	Battery voltage
      			Other than above	0
      	24		LEFT	Battery voltage
      			Other than above	0

      Door mirror RH

      (+)		(-)	Mirror switch condition	Voltage (V) (Approx.)
      Automatic drive positioner control unit
      Connector	Terminal
      M99	10	Ground	UP	Battery voltage
      			Other than above	0
      	11		LEFT	Battery voltage
      			Other than above	0
      	22		DOWN / RIGHT	Battery voltage
      			Other than above	0

   Is the inspection result normal?

   YES 

   GO TO STEP 4  .

   NO 

   Replace automatic drive positioner control unit. Refer to REMOVAL AND INSTALLATION .

4. CHECK DOOR MIRROR MOTOR
   
   

   Check door mirror motor.

   Refer to COMPONENT INSPECTION .

   Is the inspection result normal?

   YES 

   Refer to INTERMITTENT INCIDENT .

   NO 

   Replace door mirror actuator. Refer to REMOVAL AND INSTALLATION .
