2021 Land Rover Discovery SFACTORY OEM SERVICE PROCEDURE

Adaptive Speed Control Module Adjustment (G2245440): Adjustment

    • From the diagnostic tool menu, select: Service Alignment Mode.

      General Equipment: Jaguar Land Rover approved diagnostic equipment 

    • The follow indicator will now be flashing, this indicates that the vehicle is in "service alignment" and now requires driving.
    • The vehicle speed must be above 30 mph (48 kph).
    • Choose a road with plenty of stationary objects, like street lights, road signs, or barriers. Use an inside or outside lane.
    • Following vehicles too closely will obscure the stationary targets from the radar, a time gap of 2 seconds is recommended.
    • A straight road will produce a quicker and better result, although the process will still operate on a curved road.
    • When the flashing follow indicator light extinguishes, the ACC system is now functional, and a required vehicle speed can now be set by the driver and the ACC system will operate as normal.
  2. NOTE: SVR variants only.

    After the service alignment drive has been performed, drive for a further 30 minutes. If a fault occurs, re-examine the front bumper.
