1. Power Sliding Door Malfunction 2. Power Sliding Door Open/Close Switch Inoperative |
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.

⇒ | 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. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
