Power Sliding Door Module Self-Test

WARNING: This page is about a different car, the 2002 Ford Windstar. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: During the power sliding door module self-test, the power sliding door module will attempt to fully open and close the PSD. The power sliding door module self-test does not require the PARK and VSS signal to open the door. Do not carry out the power sliding door module self-test with the vehicle in motion.

The power sliding door module self-test will attempt to power open and close the power sliding door. As the power sliding door is opened and closed, the power sliding door module monitors the system for correct inputs. Upon completing the self-test, DTCs will be logged for any incorrect operations. The power sliding door module also checks the following inputs during a self-test.

overhead console on/off switch circuit
overhead console open/close switch circuit
B-pillar switch circuit
remote keyless entry circuit from the REM
PARK (enable) circuit from the REM
vehicle speed circuit from REM
fuel filler door circuit (left power sliding door only)

The power sliding door module has the ability to reverse the power sliding door operation if certain conditions exist such as obstructions or power sliding door misalignment. This is a normal function of the system, however some electrical concerns may cause the same symptom. If the power sliding door reverses during operation or self-test, always check for an obstruction or misalignment first. If no obstruction or misalignment is found, make sure to complete all DTC and symptom diagnostics before defaulting any components.
