DESCRIPTION
When the object recognition ECU is replaced with a new one, if 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 combination meter. When country specification information in the object recognition ECU and driver monitor ECU do not match, DTC C1A0C is output.
If the sensor and vehicle country specification information are the same, and the combination meter and the driving support ECU country specification information is different, C1A0A and C1A0B are output.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1A0C | While initial check is running, engine switch is on (IG) and pre-crash safety system is operating, country specification information in driving support ECU and object recognition ECU do not match for 1 second |

INSPECTION PROCEDURE
PROCEDURE
CHECK OBJECT RECOGNITION ECU
Using the intelligent tester, enter the following menus: Powertrain / Radar Cruise /. Then select "Data List".
Read the Data List and check the country specification information of the object recognition ECU and vehicle.
| Result | Proceed to |
|---|---|
| Country specification information for vehicle and object recognition ECU sensor matches | A |
| Country specification information for vehicle and object recognition ECU sensor do not matches | B |
Tech Tips
The country specification information of the driving support ECU is decided by the combination meter. Even if the vehicle and object recognition ECU country specification information matches, if the country specification information for the vehicle and driving support ECU/meter do not match, it is necessary to replace the driving support ECU and meter.
