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

- 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. As a result, a DTC may be stored.
- If the forward recognition camera has been replaced with a new one,
be sure to perform Recognition Camera/Target Position Memory and Recognition
Camera Axis Adjust.

- Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
- Inspect the fuses and relays related to this system before inspecting the suspected areas below.
