1. for LHD:
   

   1. Remove the mirror LH (Click here).
      

   2. Apply battery voltage and check the operation of the power mirror.
      

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → Terminal 7 (MV) Battery negative (-) → Terminal 8 (M+)	Turns upward (A)
      Battery negative (-) → Terminal 7 (MV) Battery positive (+) → Terminal 8 (M+)	Turns downward (B)
      Battery positive (+) → Terminal 9 (MH) Battery negative (-) → Terminal 8 (M+)	Turns left (C)
      Battery negative (-) → Terminal 9 (MH) Battery positive (+) → Terminal 8 (M+)	Turns right (D)

2. for RHD:
   

   1. Remove the mirror RH (Click here).
      

   2. Apply battery voltage and check the operation of the power mirror.
      

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → Terminal 7 (MV) Battery negative (-) → Terminal 8 (M+)	Turns upward (A)
