1. Power Sliding Door Malfunction 2. Power Sliding Door Open/Close Switch Inoperative | ||||
Circuit/System Description
As a safety feature, the power sliding door module (PSDM) monitors the park/neutral position park signal from the body control module (BCM). This prevents the opening of the power sliding door in all gear selections other than Park. If the power sliding door is open or in the process of closing when shifted out of Park (P), a chime will sound. This is a warning that the sliding door is not completely closed. Also, the driver information center (DIC) will indicate if the door is open.

Circuit/System Verification
- Ignition ON, transaxle in Park, unlock all doors and command the appropriate power sliding door to open by pressing the open/close switch on the overhead console multifunction switch. The power sliding door should open as commanded.
- Observe the scan tool Vehicle In Park parameter while moving the shifter selector from Park to Drive, the parameter should change from Yes to No.
Circuit/System Testing
- Ignition ON, shift the transaxle into Drive, verify the scan tool Vehicle in Park parameter is No.
- If all circuits test normal, replace the appropriate PSDM.
| ⇒ | If not the specified parameter, test the park/neutral position park signal circuit terminal 3 for a short to ground or short to voltage. If the circuit tests normal, replace the BCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
