The Power Sliding Door Control Unit receives inputs from the switches and sensors in the sliding door system and from B-CAN. It outputs to the slide motor, release actuator, and closer motor to control the movement of the doors. It also controls the sliding door beeper and indicator. There is one rocker switch for each door. Each switch signals its respective power sliding door control unit that the driver wants to open or close that door. The OBDII code sets when the Left Power Sliding Door Control Unit detects a Left Power Sliding Door Switch Open Side Signal Error.
