Caution / Notice / Hint

NOTE:

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 is replaced with a new one, adjustment of the millimeter wave radar sensor beam axis must be performed.

    Refer to ADJUSTMENT [10/2018 - 07/2022]

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle and a DTC may be stored.
