When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.
When the millimeter wave radar sensor assembly has been replaced with a new one, it is necessary to perform millimeter wave radar sensor assembly adjustment and front radar acceleration sensor calibration, and to clear the vehicle control history.
Front Beam Axis Adjustment
Front Beam Axis Adjustment is used to calibrate the beam axis of millimeter wave radar sensor assembly.
Perform Front Beam Axis Adjustment according to the display on the GTS.

Front Beam Axis Misalignment Reading
Front Beam Axis Misalignment Reading is used to check the amount of misalignment of the millimeter wave radar sensor assembly.
Perform Front Beam Axis Misalignment Reading according to the display on the GTS.
