Power Sliding Door

The Power Sliding Door (PSD) system is activated through the use of the following: Remote Keyless Entry (RKE), overhead console switches, B pillar switches or the DRBIII®. These inputs are hard wired to the body control module (BCM) and can be monitored with a diagnostic tool. The BCM will send the message via PCI bus to the Power Sliding Door Module (PSDM). The sliding door must be in the full open or full closed position to operate. Once the BCM sends a button activation message to the PSDM, the module shall read all inputs, outputs and vehicle conditions to determine whether it shall open, close or inhibit the PSD operation. During an opening or closing cycle, the PSDM can detect an obstacle present should it meet sufficient resistance by the hall effect sensors (integrated in the drive motor).

During an open cycle, multiple door activations (RKE, overhead console, B pillar) are ignored until the door reaches the full open position. However, during a close cycle, a 2nd door activation (RKE, overhead console, B pillar) will reverse the door to the full open position.

If the engine is cranked during a power open/close the PSD will pause then resume after engine cranking. In addition, if the vehicle is placed in gear during an open cycle, the PSD shall reverse direction and begin closing. If the vehicle is placed in gear during a closing cycle, the PSD shall continue closing until fully closed.

If the inside or outside handle is activated during an open or close cycle, the PSD will become a full manual sliding door. When the child lockout switch is "on" or "enabled", the B pillar switches are inhibited from opening a fully closed power sliding door. However, the B pillar switches are allowed to close a fully opened power sliding door.

There is only one part number for the power sliding door module (PSDM). The driver sliding door harness has an additional ground circuit which will identify it as the driver side. This eliminates the need for a left and a right side module.
