    • This procedure is required if:
    • The ACC radar needed to be removed or is misaligned in its position due to another repair operation.
    • From the diagnostic tool menu, select: Service Alignment Mode.
    • 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.
    • The time that the ACC module takes to align will vary, depending on the route, speed, number of targets, and individual module.
    • 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.
