Power Mirror Control System: Inspection

1. Check the mirror switch continuity.
   1. Left side for left/right adjustment switch:

      Measure the resistance of the mirror switch.

      Standard (Left side): 

      CONDITION RESISTANCE
      
      

      Tester Connection	Mirror Switch Position	Specified Condition
      -	OFF	10 kΩ or higher
      4 - 8 6 - 7	UP	Below 1Ω
      4 - 7 6 - 8	DOWN	Below 1Ω
      5 - 8 6 - 7	LEFT	Below 1Ω
      5 - 7 6 - 8	RIGHT	Below 1Ω

      If the result is not as specified, replace the switch assembly.

   Measure the resistance of the mirror switch.

   Standard (Right side): 

   CONDITION RESISTANCE
   
   

   Tester Connection	Mirror Switch Position	Specified Condition
   -	OFF	10kΩ or higher
   3 - 8 6 - 7	UP	Below 1Ω
   3 - 7 6 - 8	DOWN	Below 1
   2 - 8 6 - 7	LEFT	Below 1Ω
   2 - 7 6 - 8	RIGHT	Below 1Ω

If the result is not as specified, replace the switch assembly.

1. Disconnect the outer rear view mirror assembly LH connector.
2. Inspect the mirror motor operation.
   1. Apply battery voltage as shown in the table.

   Standard: 

   BATTERY CONNECTION SPECIFICATION
   
   

   Battery Connection	Mirror Operation
   Positive (+) -MV(3) Negative (-) -Com(2)	TURNS UPWARD (A)
   Positive (+) -Com(2) Negative (-) -MV(3)	TURNS DOWNWARDS (B)
   Positive (+) -Com(2) Negative(-) -MH(1)	Turns left (C)
   Positive (+) -MH(1) Negative (-) -Com(2)	Tums right (D)

If the result is not as specified, replace the mirror assembly.
