DTC 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 stored.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1A0A | When the power switch is on (IG), the country code of the driving support ECU and millimeter wave radar sensor do not match for approx. 1 second. |
