How to manage the rise of ADAS faults in independent workshops
Advanced Driver Assistance Systems (ADAS) are no longer a luxury feature found only on premium models. Systems such as lane keep assist, adaptive cruise control, autonomous emergency braking, blind spot monitoring and traffic sign recognition are now standard across much modern vehicles.
These technologies greatly improve safety and driver confidence, but, as Launch Tech points out, they also bring a growing challenge for independent workshops. ADAS faults are increasing rapidly, and they are becoming a routine part of daily diagnostics.
Why ADAS faults are becoming more common
1. More systems and more sensors
Modern vehicles rely on a network of cameras, radar units, ultrasonic sensors and ECUs. Each component must operate in perfect alignment. Even a small misalignment, communication error or software mismatch can cause an ADAS fault, warning lights or reduced system performance.
2. Everyday workshop jobs now affect ADAS
Routine tasks such as windscreen replacement, wheel alignment, suspension repairs, bodywork and even tyre changes can trigger an ADAS fault. A radar hidden behind a bumper or a camera mounted behind a windscreen may require calibration after work that previously had no electronic impact. If calibration is not carried out correctly, an ADAS fault is almost unavoidable.
3. Software updates and rising vehicle complexity
ADAS systems rely heavily on software. Manufacturers frequently release updates to refine behaviour, improve safety thresholds or fix known issues. Vehicles with outdated software often present ADAS faults that appear to be hardware-related but are rooted in outdated software. Without access to advanced diagnostics and OE-level functions, these faults become extremely difficult to pinpoint.
4. Environmental and usage factors
Dirty windscreens, weather conditions and minor knocks that leave no visible damage can all result in an ADAS fault warning.
The risk of falling behind
ADAS faults are not just another dashboard light. Incorrect repairs, missed calibrations, or incomplete diagnostics carry serious safety implications. There are also insurance and legal considerations for workshops. A wrongly diagnosed fault can easily lead to comebacks, liability risks and reputational damage. For some independents, the fear of misdiagnosing an ADAS fault has led to turning work away unnecessarily.
How workshops can keep up
1. Invest in professional diagnostic equipment
Basic code readers are no longer sufficient. Workshops need diagnostic tools that can access ADAS systems, read manufacturer-specific fault codes, carry out calibrations and guide technicians through the required procedures. The right tool helps identify faults accurately and gives technicians confidence in their repairs.
2. Understand calibration requirements
Manufacturers have different requirements for static and dynamic calibration. Knowing when calibration is required and how to verify a successful result is essential. Modern diagnostic platforms can guide technicians step by step, reducing the risk of repeat ADAS faults.
3. Stay up to date with training and software
ADAS technology evolves quickly. Ongoing training and up-to-date diagnostic software are essential for staying competitive. Keeping systems current ensures full coverage of the latest vehicles and helps prevent avoidable faults caused by outdated information.
4. Educate customers
Many drivers are unaware that common repairs can affect safety systems. Explaining why calibration is necessary and how it prevents future ADAS faults helps build trust. Transparency can turn ADAS work into a valued part of your service offering.
Turning ADAS challenges into opportunities
Launch Tech sees this shift every day in the questions workshops ask and the ADAS fault issues they are struggling to diagnose.
Workshops that embrace ADAS diagnostics now will be best prepared for the future of vehicle repair. With the right equipment, training and support, faults become less of a challenge and more of an opportunity to offer a profitable, high-value service.
Launch Tech supports workshops with advanced diagnostic solutions, ADAS calibration equipment, training and ongoing technical assistance. For more info visit www.ryansautomotive.ie or call 051 424799.
Ryans Automotive will be exhibiting at the 2026 Auto Trade EXPO, which takes place alongside the CV Workshop EXPO from 10th -11th October at the RDS Simmonscourt in Dublin.
