C1A14 on Nissan
Front Radar Sensor Beam Axis Not Adjusted
C1A14 on Nissan vehicles indicates front radar sensor beam axis not adjusted. Au7o has documented this code across 1 Nissan model — most commonly on Sentra. C1A14 is a manufacturer-specific chassis code (documented on Nissan/Infiniti) indicating the front radar sensor's beam axis (aim) has not been adjusted or calibrated. This radar sensor supports advanced driver-assistance features such as adaptive cruise control and forward collision warning/automatic braking. When the sensor is misaligned or its alignment has not been completed, the module disables those ADAS features and sets the code. Often appears after a front-end repair, windshield/bumper work, or a collision. Confirm against the factory manual. Typical repair costs on Nissan range from $600 to $1,400, depending on the specific model and root cause.
Common Causes of C1A14
- •Radar sensor not calibrated/aligned after service
- •Sensor or bracket physically misaligned
- •Front-end collision or bumper/grille repair
- •Damaged sensor or mounting bracket
- •Damaged wiring or connector
- •Radar/ADAS control module fault
C1A14 on Nissan by Model
Nissan Sentra(1 issue)
- Forward Emergency Braking (AEB) Phantom Activation2015-2021
Sentras equipped with Nissan's Forward Emergency Braking / Automatic Emergency Braking apply the brakes hard for non-existent obstacles ('phantom braking'). The Bosch radar module behind the front grille (sensor assembly p/n 28438-5UD0A) produces false positives, frequently triggered by overpasses, bridges, railroad tracks, parking-garage walls, and metal grates. Nissan disclosed 1,233 related consumer complaints to NHTSA for the Rogue/Rogue Sport/Sentra, including dozens of minor collisions and injury allegations, and the defect is the subject of class-action litigation.
