- Spiral with sensor cable sub-assembly
- Forward recognition camera
| CAUTION / NOTICE / HINT
NOTICE:
- 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
