Why cameras and sensors need checks after crash repairs
A collision repair and driver assistance systems specialist explains
Lane keeping, automatic braking and adaptive cruise control rely on cameras, radar and sensors. They also rely on where those parts are mounted. A fixed bumper or windshield can look normal while a linked system still needs a check or calibration. A dashboard with no warnings doesn’t prove every system works right. [1, 2]
Find out which features your vehicle has
Tell the repair shop your exact model and trim level. Ask which driver assistance features the vehicle has and which parts were taken off, replaced or disturbed. The shop should look up the vehicle maker’s instructions for scans and calibration. Some procedures need special targets. Others call for a controlled test drive. What’s needed depends on the vehicle and the repair. [1, 2]
Get the repair record in writing
Ask for the scan results from before and after the repair. Request the maker’s required calibration steps and the final calibration report, if one applies. If a step couldn’t be finished, find out why and what’s still left to do. A warning light that goes out can’t stand in for all the required checks. Let the shop know if a feature acts differently after the repair. [1]
Know what these features can and can't do
Driver assistance features back up your attention. They can’t take its place. When you pick up the car, check that the settings you use are turned on the way you want. Read up on any limits listed in the owner’s manual. [1]
The car may brake out of nowhere, miss lane lines or show new warnings. If so, stop relying on that feature. Get it inspected promptly. [1]
Questions when you pick up the car
- Which systems did this repair affect?
- Which scans and calibrations were required, and were they all done?
- Can I get copies of the final reports?
See the calibration list on the repair order
Ask the shop to list the calibration requirements for your specific vehicle on the repair order. [1]
