DTC C1A0A: Front Radar Sensor Region Code Mismatch [09/2014 - 10/2015]: 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 stored.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1A0A | While the initial check is running, the engine switch is on (IG) and the pre-collision system is operating, the country specification information in the driving support ECU and the front millimeter wave radar sensor do not match for 2 seconds or more. |
