DTC C1A0A: Front Radar Sensor Region Code Mismatch [08/2013 - ]: Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
The driving support ECU assembly uses the millimeter wave radar sensor to detect obstacles in front of the vehicle.
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 the country specification information from the main body ECU. When the country specification information in the sensor and ECU do not match, DTC C1A0A is stored.
