Code C1A14 Description

The C1A14 diagnostic trouble code indicates that the front radar sensor beam axis is not properly adjusted. This sensor is a crucial component of the vehicle's advanced driver assistance systems (ADAS), specifically the adaptive cruise control and collision avoidance systems. When the beam axis is not adjusted correctly, it can lead to inaccurate detection of objects and potential malfunctions in these safety systems. This issue can compromise the vehicle's ability to maintain a safe following distance, respond to potential collisions, and provide accurate warnings to the driver.

Tech Notes for C1A14

When replacing the Driving Support ECU Assembly, make sure to replace it with a new one. If a device that was installed on another vehicle is used, the information stored in the Driving Support ECU Assembly will not match the information from the vehicle, and as a result, a DTC may be stored.
When the Millimeter Wave Radar Sensor Assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed.
If the Forward Recognition Camera has been replaced with a new one, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust.
