CAUTION / NOTICE / HINT
NOTICE:
- When replacing the millimeter wave radar sensor assembly, make sure to replace it with a new one. If a device 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 as a result, a DTC may be stored.
- When the millimeter wave radar sensor assembly is replaced with a new
one, adjustment of the radar sensor beam axis must be performed.
