Circuit/System Description

The Driver Door Switch (DDS) or Passenger Door Switch (PDS) controls the mirror horizontal and vertical motors through the use of bi-directional motor controls. When the mirror is commanded up, voltage is supplied to the mirror vertical motor through the Left/Right Mirror Motor-Up/Right Control circuit and ground is supplied through the Left/Right Mirror Motor Down Control circuit. When the mirror is commanded down, voltage is supplied to the mirror vertical motor through the Left/Right Mirror Motor Down Control circuit and ground is supplied through the Left/Right Mirror Motor-Up/Right Control circuit.

Horizontal controls operate in the same manner with the Left/Right Mirror Motor-Up/Right Control circuit supplying voltage and the Left/Right Mirror Motor Left Control circuit supply a ground to the mirror horizontal motor when the mirror is commanded right. When the mirror is commanded left, voltage is supplied to the mirror horizontal motor through the Left/Right Mirror Motor Left Control circuit and ground is supplied through the Left/Right Mirror Motor-Up/Right Control circuit.
