Tech Notes for C1A71 2017 Toyota RAV4

When replacing the Forward Recognition Camera, always replace it with a new one. If a Forward Recognition Camera which was installed in 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 Forward Recognition Camera learning.
