This procedure is required if:
A new ACC radar and, or ACC module are installed.
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.
