Power Sliding Door System: Description

Power Sliding Door is an electro-mechanical system designed to provide power opening and closing of a vehicle's sliding door through the push of a button of the transmitter key or the main control buttons on the overhead console or the sub control buttons on the center pillar trim or inside/outside door handle switch.

The power sliding door will reverse direction of travel if resistance to movement is detected while the door is being closed. If resistance to movement is detected while the power sliding door is being opened, the door will stop moving.

1. DRIVE UNIT

   Drive unit (A) consists of a DC motor, optical sensor, clutch, cables and pulleys and wire harness. The clutch and motor portion of the assembly provides the power and torque required to open or close the sliding door. The clutch assembly is used to connect or disconnect the motor so that the Sliding Door may be moved manually, if desired.

2. POWER SLIDING DOOR CONTROL MODULE (PSDM)

   The PSD System uses a power sliding door control module (microprocessor controller) to operate the drive unit. Signals are received from the vehicle and used to start or stop power open or close operations. The PSDM cannot be adjusted or repaired and if found to be faulty, must be replaced.

4. ANTI-PINCH STRIP (D)

   Secondary Obstacle Detection is provided by means of a contact type strip. Strip is composed of two conductive zones separated by an air gap. When strip is compressed, conductive zones make contact, activating the switch signal.

   Copper wire is extruded through conductive material to prevent resistive buildup. Terminating resistor is molded into end of strip to detect failures of strip.
