Power Door Lock Motors

Each door module supplies battery positive voltage and ground, through the door lock actuator motor drive circuits to its associated door lock actuator motor. The power door lock motors are reversible. The function performed by the lock motor (Lock or Unlock), depends on which motor drive circuit the battery positive voltage is applied to, and which motor drive circuit the ground is applied to. To perform a lock function, the module applies battery positive voltage to the door lock motor Lock circuit, and ground to the door lock motor Unlock circuit. To perform a Unlock function, the module reverses the polarity and applies battery positive voltage to the door lock motor Unlock circuit, and ground to the door lock motor Lock circuit.
