DTC C1AA1: FCM Destination Information Unmatched [10/2015 - ]: Description
WARNING: This page is about a different car, the 2018 Toyota Avalon, 2017 Toyota Avalon, and 2016 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
When the forward recognition camera is replaced with a new one, the new forward recognition camera attempts to store country specification information received from the main body ECU (multiplex network body ECU) and hybrid vehicle control ECU assembly. If the country specification information stored in the forward recognition camera is different from that stored in the main body ECU (multiplex network body ECU) or hybrid vehicle control ECU assembly, DTC C1AA1 is stored.
