Power Sliding Door System

POWER SLIDING DOOR SYSTEM

POWER SLIDING DOOR
The Power Sliding Door (PSD) system is activated through the use of the following: Remote Keyless Entry (RKE), overhead con sole switches, B pillar switches or the DRBIII(R). These inputs are hardwired 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 whet her 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. The child lockout is mechanical only and has no effect on the B-pillar switch as it did in previous models.

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.

DIAGNOSTIC FEATURES
The PSDM can be flashed on vehicle via PCI bus with a DRBIII(R) diagnostic tool. The DRBIII(R) can read all inputs, actuate all outputs, read module information, and read diagnostic trouble codes. As a reminder, some DTC's can be set during normal PSD operation.

SYSTEM INHIBITORS
1. Battery voltage too high or too low (above 16V, below 9.5V)
2. Vehicle in gear
3. Vehicle speed > 0 mph/km/h
4. 0/H console lockout will inhibit the B pillar switches
5. Doors locked will inhibit all interior switches from opening (Overhead Console, B Pillar). A locked sliding door can be power closed.
