PRE-COLLISION: PRE-COLLISION SYSTEM: C1A0A: Front Radar Sensor Region Code Mismatch
C1A0A - Front Radar Sensor Region Code Mismatch
DESCRIPTION
The driving support ECU uses the millimeter wave radar sensor to detect obstacles in front of the vehicle.
Based on this information, the driving support ECU sends pre-collision control operation signals.
When the millimeter wave radar sensor 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, ECU and/or main body ECU do not match, DTC C1A0A is output.
