HINT:
This DTC is stored when the country specification information stored in the forward recognition camera and that stored in the main body ECU (multiplex network body ECU) do not match. If the forward recognition camera or main body ECU (multiplex network body ECU) has been replaced, check if a forward recognition camera or main body ECU (multiplex network body ECU) from another vehicle was used.
PROCEDURE
