The power sliding door (PSD) is designed to stop and reverse direction when an obstruction is present. Proper mechanical operation of the PSD is necessary for power open and close functions to occur.
- Manually open and close the PSD slowly in order to determine if the door operates smoothly and without excessive resistance.
- Clean and lubricate or replace the tracks as necessary and verify proper PSD cable tension.
- Verify that the door and latches are aligned and operate properly.
