MIRROR SENSOR
PASSENGER SIDE
PASSENGER SIDE : DescriptionINFOID:0000000003775618
The mirror sensor RH is installed to the door mirror actuator RH.
The resistance of 2 sensors (horizontal and vertical) is changed when the door mirror RH is operated.
Automatic drive positioner control unit calculates the door mirror position according to the change of the volt-
age of 2 sensor input terminals.
