Pinch Sensor Malfunction,
Diagnostic Overview
The System: The Tesla Model X Falcon Wing Doors (FWD) are complex robotic systems featuring dual-hinges (primary and secondary), electric actuators, and a suite of "hidden" ultrasonic sensors located behind the door's skin.
The Problem: Failures range from "ghosting" (the door stops moving because it thinks an object is in the way) to physical misalignment where the door rubs against the roof glass or "falcon wing" seals.
Common Failure Points
Ultrasonic Sensor (USS) "Blindness": These sensors use sound waves to "see" through the aluminum door skin. If the adhesive holding the sensor to the inside of the door fails, the sensor sags, causing the door to detect a permanent "ghost" obstruction and refuse to open or close.
Latch Actuator Failure: The lower cinching latch often fails electrically. If the latch doesn't "communicate" that it is fully open, the computer won't allow the motors to begin the lifting sequence.
Primary Hinge Wear: The main hinges carry immense weight. Over time, the bolts can slightly loosen or the bushings wear, causing the door to sag. This leads to the door hitting the brightwork (chrome trim) or the roof glass during operation.
Pinch Sensor (Seal) Damage: The black rubber seals along the edges of the door contain pressure-sensitive strips. If these strips are kinked or water-damaged, they will trigger a "Pinch Detected" error, reversing the door's direction.
Troubleshooting Steps
Visual Clearance Check: Inspect the "spine" (the glass roof section between the doors). Look for scratch marks or paint chips. If you see them, your hinges are misaligned and require professional adjustment to prevent the glass from shattering.
The "Manual Override": If a door refuses to move due to a "ghost" obstruction, you can usually force it by holding the door button on the center console or the B-pillar.
Warning: Only do this if you are 100% certain there is no physical ceiling or object in the way.
Sensor Calibration: Sometimes the door "loses its place." You can attempt a recalibration by fully opening and then fully closing the door via the center screen without interruption.
Latch Lubrication: Use a dry silicone spray on the lower latch mechanism. If the latch is sticky, the "cinching" motor may time out, triggering a dashboard error.
Critical Safety Note
Warning: Never attempt to adjust the primary hinge bolts yourself. These doors are under significant tension and are heavy enough to cause serious injury or shatter the panoramic roof glass if they fall out of alignment.
