Faults → Read
2 – Check the current misalignment angle.
Module: 13 (ACC radar)
Live data → misalignment angle
The perfect setting is 0.00. The tolerance is between -0.80 and 0.80 degrees. Values below -0.80 mean that the radar is too far to the right. Values above 0.80 mean that the radar is too far to the left. One turn of the adjustment screw is equivalent to 1 degree.
Remove the radar head cover. Use the adjustment screws to change the position of the radar. Replace the cover.
