When Is ADAS Recalibration Required?
Recalibration is required any time a camera, radar, or sensor — or its mounting point — is disturbed. That covers collision repair, windshield replacement, wheel alignment, suspension work, bumper or sensor removal and replacement, and many stored fault codes. The exact triggers vary by manufacturer.
The repair triggers
These are the common events that require a recalibration:
- ✓Windshield or glass replacement (glass-mounted camera)
- ✓Wheel alignment or suspension / ride-height change
- ✓Bumper, grille, or exterior work over a radar or sensor
- ✓Sensor, camera, or radar removal, replacement, or aiming
- ✓Collision or structural body repair, or SRS deployment
- ✓Module reprogramming or a software update
- ✓A stored fault code (DTC) or a warning message
How it varies by make
Every manufacturer documents its own triggers and procedures. Some require a wheel alignment before any calibration; some require genuine glass; some require both static and dynamic calibration. For the make-specific requirements — and the OEM bulletin behind each — see our per-manufacturer ADAS calibration requirements pages.
Why a clear warning light isn't proof
A sensor can be out of aim and still report no fault. The system may simply trust bad input. That's why recalibration is tied to the repair event, not to whether a warning light is on — and why post-repair documentation matters.
Frequently asked
Quick answers
- Does a wheel alignment require an ADAS calibration?
- Often yes. Many OEMs require recalibration after an alignment or suspension change because the sensors are aimed relative to the vehicle's geometry. Several require the alignment to be correct before calibration even begins.
- Is calibration needed if no warning light is on?
- It can be. A camera or radar can be out of aim without setting a fault, so recalibration follows the repair event — not the dashboard. Documentation proves it was done correctly.
