Land Rover Discovery: Seat Position Sensor -
Notes on Removal / Replacement
NOTE:
NAS vehicles have a seat position sensor fitted to both the driver and
passenger-side seats.
The seat position sensor, a hall-effect sensor, is fitted to the underside of
both the driver and passenger-side seats on NAS vehicles. It should be
noted that these sensors cannot be re-installed once removed. If any work is
undertaken that requires removal of the seat position sensor, a NEW sensor
MUST be fitted. Note that different sensors are fitted to left-side and
rightside
seats, so care should be taken to ensure the correct replacement parts
are installed
