Toyota Avalon Service & Repair Manual: FCM Destination Information Uninitialized (C1AAA)

DESCRIPTION

When the forward recognition camera is replaced with a new one, the new forward recognition camera attempts to store the country specification information received from the main body ECU (multiplex network body ECU). If the forward recognition camera cannot store the country specification information, DTC C1AAA is stored.

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 sure to perform forward recognition camera adjustment.
