ADAS Guide

Faults with ADAS

How do you know if you have a fault with your ADAS?

There are times when you will need your ADAS recalibrated, including:

After your windscreen has been replaced
When the dashboard shows a fault
When your camera has been disconnected, whether this be from maintenance or bad terrain
After any suspension work
After any wheel alignment work

Windscreen replacements have a knock-on effect on all ADAS systems, so if your vehicle has any of the following repaired or replaced, your cameras will require recalibration:

Adaptive cruise control
Adaptive headlights
Automatic parking
Automotive night vision
Blind spot monitor
Collision avoidance system
Driver drowsiness detection
Driver monitoring system
Forward collision warning
Lane departure warning system
Lane change assistance
Pedestrian protection system
Traffic sign recognition

What to do when you have a fault with your ADAS

Something as simple as a windscreen replacement may affect ADAS calibration. It’s crucial you get an experienced professional to recalibrate your ADAS systems to ensure they are working correctly. When we do our windscreen replacements, we ensure your ADAS systems are recalibrated before we send you on your way.

There are two different kinds of calibration:

Mobile calibration

This is where a handheld device is plugged into the car, then the car is driven at a prescribed speed in order to accustom the car to certain conditions. The vehicle manufacturer will give the specifications to ensure you are calibrating the vehicle correctly.

Fixed calibration

This type of calibration is carried out in a specially-designed workspace. It requires a specialist Camera and Sensor Calibration Tool and technicians reference manufacturer calibration settings to ensure an accurate result.
