Why Alignment Matters for ADAS

ADAS and wheel alignment are more connected than most people realize!

Advanced Driver Assistance Systems (ADAS) rely on precisely calibrated sensors and cameras to function correctly.
These components are often mounted in places affected by wheel alignment—like the front bumper, windshield, and suspension.
Even a slight misalignment can throw off the system’s ability to detect lanes, vehicles, or obstacles.

What Happens During Alignment with ADAS

• Standard Alignment: Adjusts wheel angles (camber, caster, toe) so the car drives straight and handles properly.
• ADAS-Specific Alignment: Includes recalibrating sensors and cameras to match the new wheel geometry. This is often called a Safety Systems Alignment.

What Can Go Wrong Without Calibration

• Lane departure warnings may trigger incorrectly—or not at all.
• Adaptive cruise control might misjudge the distance to the car ahead.
• Parking assist and backup cameras could show inaccurate paths.
• Steering angle sensors may miscommunicate with the system.

Calibration After Alignment

After any alignment, especially if toe or thrust angles are adjusted, ADAS recalibration is essential. This ensures the system’s “eyes”
and “brain” are synced with the car’s new orientation3.




Tools & Tech

Modern shops use:

• High-tech alignment racks that double as calibration stations
• Scan tools to initiate calibration routines
• argets and fixtures to help cameras and radar recalibrate accurately
So next time your car gets an alignment, make sure the shop knows it’s ADAS-equipped. Want help call Precision Collision Center in Centralia Washington at (360)807-4239.
