DTC C1A0A: Front Radar Sensor Region Code Mismatch [08/2015 - 08/2019]: Description
The driving support ECU uses the millimeter wave radar sensor assembly, lane recognition camera sensor assembly*1 and driver monitor camera*2 to detect obstacles in front of the vehicle and the direction that the driver head is facing. Based on this information, the driving support ECU 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. Also, when the driving support ECU is replaced with a new one, it receives country specification information from the main body ECU. When country specification information in the sensor and driving support ECU do not match, DTC C1A0A is output.
- *1: w/ Lane Departure Alert System
- *2: w/ Driver Monitor Camera
