UTILITY

NOTICE:

• When replacing a millimeter wave radar sensor assembly, replace it with a new one. When the millimeter wave radar sensor assembly is replaced with a new one, it stores the country specification information received from the driving support ECU assembly.

  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.

• If the millimeter wave radar sensor assembly has been replaced or removed/installed, be sure to perform Front Beam Axis Adjustment. If not performed, DTC C1A14 will be stored when the system is turned on.
