DESCRIPTION
When a new millimeter wave radar sensor assembly is installed, it receives vehicle specification information (destination, steering wheel position, 2WD or 4WD, etc.) from the main body ECU (multiplex network body ECU) and stores the information.
DTC C1A02 is stored when the millimeter wave radar sensor assembly cannot store the vehicle specification information from the main body ECU (multiplex network body ECU).
