DESCRIPTION

The forward recognition camera receives vehicle information from the ECM via CAN communication.

If the forward recognition camera cannot store the vehicle information, it will store this DTC.

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 and a DTC may be stored.
If the forward recognition camera has been replaced with a new one, forward recognition camera adjustment must be performed.
