DTC C1A0A: Front Radar Sensor Region Code Mismatch [09/2015 - ]: Description
The driving support ECU assembly uses the millimeter wave radar sensor assembly to detect obstacles in front of the vehicle. Based on this information, the driving support ECU assembly sends pre-collision control operation signals.
When the millimeter wave radar sensor assembly is replaced with a new one, it acquires the country specification information from the driving support ECU assembly. Also, when the driving support ECU assembly is replaced with a new one, it receives country specification information from the combination meter assembly. When country specification information in the sensor and ECU do not match, DTC C1A0A is output.
