DESCRIPTION
When the object recognition ECU is replaced with a new one, it acquires the country specification information from the driving support ECU. Also, when the driving support ECU is replaced with a new one, it receives the country specification information from the No. 1 meter ECU sub-assembly. When the country specification information in the object recognition ECU and driving support ECU do not match, DTC C1A0C is stored.
