CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: C1A0A: Front Radar Sensor Region Code Mismatch
C1A0A - Front Radar Sensor Region Code Mismatch

DESCRIPTION

When the front 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 the country specification information from the combination meter. When the country specification information in the sensor and ECU do not match, DTC C1A0A is output.





INSPECTION PROCEDURE

NOTICE:
When the front millimeter wave radar sensor is replaced with a new one, adjustment of the radar sensor beam axis must be performed Adjustments.

PROCEDURE

HINT
- The country specification information of the driving support ECU is decided by the combination meter. Even if the country specification information for vehicle and sensor match, if the country specification information for the vehicle and ECU/meter do not match, it is necessary to replace the ECU and meter.
- When the country specification information (North America to Europe/Europe to North America) for the vehicle and sensor do not match, the sensor's information can be overwritten by performing the sensor's axis adjustment.

B -- REPLACE FRONT MILLIMETER WAVE RADAR SENSOR Removal

C -- ADJUST FRONT MILLIMETER WAVE RADAR SENSOR Adjustments

A -- REPLACE DRIVING SUPPORT ECU AND COMBINATION METER
