Description & Operation

Vehicle may be equipped with passenger-side and driver-side Power Sliding Doors (PSD). Each PSD will have its own control module and operate independently. Both the Left Power Sliding Door Module (LPSDM) and Right Power Sliding Door Module (RPSDM) have specific outputs to control PSD operation. The main switch for PSDs is the overhead console on/off switch. For power assist functions to operate the overhead console on/off switch must be in ON position. PSDs are designed to open and close using the overhead console open/close switch, "B" pillar switch or using Remote Keyless Entry (RKE) transponder. PSDs must be unlocked before power assisted operation of sliding doors will occur (except RKE activation). Fuel filler door must be closed to allow left PSD operation. The Rear Electronic Module (REM) signal inputs and control switches are specific for LPSDM or RPSDM, except for overhead console on/off switch input, REM Park input, REM vehicle speed input and fused battery logic circuit. Power sliding door system components and their operation is as follows:

1. Actuator Drive Assembly Clutch
   
   Actuator drive assembly clutch separates actuator drive assembly motor from cable spool. This allows for manual opening and closing of power sliding doors without driving the motor.
2. Actuator Drive Assembly Motor
   
   Actuator drive assembly motor is a reversible motor. Upon valid activation, PSD module supplies power and ground to motor circuits depending on PSD position and direction PSD needs to be moved.
3. "B" Pillar Open/Close Switch
   
   Pressing "B" pillar open/close switch sends a momentary ground signal to PSD module. Upon receiving input, PSD module checks overhead console on/off switch position. If overhead console on/off switch is in ON position, PSD module sends power to PSD motor. If overhead console on/off switch is in OFF position, PSD motor will not be supplied with power from PSD module.
4. Latch Release Actuator
   
   PSD must be unlocked to allow PSD to open. Power is supplied to release actuator by LPSDM/RPSDM when a valid open command is received. Latch release actuator unlatches related PSD, similar to manual sliding door operation from door handle. PSD module is unable to detect if PSD is locked or unlocked. If activated while PSD is locked, latch release actuator will operate, but PSD will not open until door is unlocked.
5. Overhead Console On/Off Switch
   
   Overhead console on/off switch supplies a ground signal when in ON position to enable "B" pillar open/close switch activation and power assist activation of PSD. Both functions are disabled when overhead console on/off switch is in OFF position. Remote Keyless Entry (RKE) operations are not affected by overhead console on/off switch position.
6. Overhead Console Open/Close Switch
   
   Pressing overhead console open/close switch supplies a momentary ground signal to LPSDM/RPSDM. If conditions are correct, LPSDM/RPSDM will engage power assist operation to power-open or power-close PSD. Overhead console on/off switch does not affect the overhead console open/close switch.
7. Position Sensor
   
   Position sensor is located on drive assembly actuator for Power Sliding Doors (PSD). Position sensor is used by LPSDM or RPSDM to record position of related PSD.
8. Power Sliding Door (PSD) Latch Switch
   
   PSD latch switch is located on rear PSD latch and identifies latch switch position by supplying a ground signal to LPSDM or RPSDM for open and lose operations. PSD latch switch circuit is connected through sliding door contacts.

Power sliding doors will operate as long as vehicle is in Park position (provided by PCM) and/or vehicle wheel speed sensors read less than 6 MPH (provided by Anti-Lock Brake System/Traction Control (ABS/TC) module). REM will prevent PSD operation in the event either of these 2 messages are invalid or missing. These 2 inputs have network DTCs and if they are retrieved and power sliding doors are not operating, repair these DTCs first. Power sliding doors can be closed regardless of Park or vehicle speed status.
