INSPECT MIRROR POSITION SENSORS OPERATION 

HINT:

Strip off the vinyl tape of the connector and remove terminals 1, 2, 6, 8, 9, 10 and 11 from the connector housing.

  1. Connect a series of three 1.5 V dry cell batteries.
  2. Connect the positive (+) lead from the dry cell batteries to terminal 8 and the negative (-) lead to terminal 11.
  3. Connect the positive (+) lead from the voltmeter to terminal 9 and the negative (-) lead to terminal 11.
  4. Apply battery positive voltage to terminals 2 and 6, then check that the voltage gradually changes according to the table below while the mirror moves between the uppermost position and lowermost position.
    MIRROR POSITION SENSORS POSITIONS

    Mirror position Lowermost Mirror position Uppermost
    Voltage 2.8-5.0 Changes gradually 0-1.8

    If voltage value is not as specified, replace the motor assembly.
