Battery negative (-) → Terminal 7 (M+)

Turns upward

Battery positive (+) → Terminal 7 (M+)

Battery negative (-) → Terminal 3 (MV)

Turns downward

Battery positive (+) → Terminal 6 (MH)

Battery negative (-) → Terminal 7 (M+)

Turns left

Battery positive (+) → Terminal 7 (M+)

Battery negative (-) → Terminal 6 (MH)

Turns right

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

(b) Check the operation of the mirror heater. (w/ Mirror Heater)
