Battery Connection

Specified Condition

Battery positive (+) → Terminal 1 (MV)

Battery negative (-) → Terminal 10 (M+)

Turns upward

Battery positive (+) → Terminal 10 (M+)

Battery negative (-) → Terminal 1 (MV)

Turns downward

Battery positive (+) → Terminal 9 (MH)

Battery negative (-) → Terminal 10 (M+)

Turns left

If the result is not as specified, replace the outer rear view mirror assembly RH.

(b) Check the operation of the retractable mirror. (for TMMC Made)

NOTICE:

  • Disconnect and reconnect the battery between each mirror position check.
  • The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.
  • If the motor is kept energized, even after each mirror position check, it may lead to a motor malfunction. Make sure to disconnect the battery immediately after performing each mirror position check.

(1) Disconnect the outer mirror actuator assembly RH connector.
