B1544 CHEVROLET MeaningThe Driver Door Module (DDM) or Passenger Door Module (PDM) controls the mirror horizontal and vertical motors through the use of bi-directional motor controls. When the mirror is commanded up and down, voltage or ground is supplied to the mirror vertical motor through the mirror motor vertical control circuit and voltage or ground is supplied through the mirror motor common control circuit.
Horizontal controls operate in the same manner with the mirror motor horizontal control circuit supplying voltage or ground and the mirror motor common control circuit supplying voltage or ground to the mirror horizontal motor when the mirror is commanded right and left.
