Why Is My Adaptive Cruise Control Not Working?
Adaptive Cruise Control (ACC) is designed to automatically maintain a safe following distance from the vehicle ahead using front radar sensors and forward-facing cameras. When the system detects a fault, warning lights may appear on the dashboard and adaptive cruise control may stop functioning completely.
Common Causes Of Adaptive Cruise Control Faults
There are several reasons why adaptive cruise control may stop working, including:
- Front radar misalignment
- Windscreen replacement
- Front bumper repairs
- Accident damage
- Forward camera calibration faults
- Suspension repairs or wheel alignments
- Wiring or communication faults
- Radar sensor obstruction
Even small changes to radar or camera alignment can affect how the system calculates distance, speed and surrounding traffic conditions.
Why Calibration Is Important
Modern ADAS systems rely on precise calibration to operate safely and accurately. If the radar or forward camera becomes even slightly misaligned, the system may disable itself to prevent incorrect braking or collision responses.
In many cases, professional radar calibration or forward camera calibration is required after repairs or component replacement to restore proper system operation.
