I was replying to the comment if blind spot detection still worked with the doors off. Cross path and everything works fine, but at least on mine, when the doors are off, it disables BSM. Not an error, just a note that it's disabled. When I put the doors back on, BSM works fine.Yes, in the tail light, which is why it ALSO works for cross-path detection in reverse.
From the part listing:
For Jeep Gladiator's that have the factory Blind Spot and Cross Path detection network on-board, this Mopar Blind Spot Sensor will replace a malfunctioning unit found inside the rear tail lamp. No need to replace the entire tail lamp when only the sensor is failing. This unit plugs into the wiring in the tail lamp on either the driver or passenger side and restores the safety features from the factory. Since the computer on board is already familiar with this part, there is no need to flash the system when its installed, so you can get back on the road with having to visit your local dealership.
This is a replacement sensor for factory installed systems. This does not add features to an unequipped vehicle.
