Essential Do’s & Don’ts for ADAS Sensors in Collision Repair

Essential Do’s & Don’ts for ADAS Sensors in Collision Repair

By Chris Bonneau | February 4, 2025

Advanced Driver Assistance Systems (ADAS) are now standard in modern vehicles, providing critical safety and convenience features that help prevent accidents. Many of these systems rely on sensors that must be carefully handled during repairs.

As an auto body or collision repair shop, understanding how ADAS sensors function and how to properly service them can help you avoid costly mistakes, increase profitability, and enhance customer satisfaction.

Common ADAS Features Found in Modern Vehicles

ADAS features vary by manufacturer and are powered by sonar, radar, cameras, or other sensors. Some of the most common include:

Automatic Emergency Braking
Blind Spot Detection
Auto Parking Assist
Night Vision
Automatic Collision Avoidance
Driver Alertness Warnings
Adaptive Cruise Control
Pedestrian Detection

These systems are highly sensitive and often require recalibration after repairs. Before we cover what not to do when working with ADAS-equipped vehicles, let’s go over best practices.

Do’s for Auto Body Shops Working with ADAS Sensors

According to a recent AASA study, only 30% of repair shops—both independent and dealership-affiliated—are equipped to recalibrate and repair ADAS sensors. This means many shops are outsourcing these repairs, losing out on a major revenue stream. Mastering ADAS repairs can be a game-changer for your shop’s profitability.

Here’s what every collision repair shop should do when working with ADAS-equipped vehicles:

1. Identify All ADAS Sensors and Their Locations

Knowing which sensors a vehicle has—and where they are located—is crucial before starting any repair. Misplacing or damaging a sensor can compromise the system, leading to improper operation and safety risks.

Solution: SUN® Collision Repair Information provides detailed repair data for all vehicle makes and models, helping technicians quickly locate ADAS sensors, understand their functions, and follow manufacturer-specific repair guidelines. Interactive wiring diagrams also simplify diagnostics.

2. Keep ADAS Connectors and Sensors Clean

Radar- and sonar-based sensors, such as those used for parking assist and blind spot detection, must be free of dirt, debris, and other contaminants. A dirty sensor can misinterpret its surroundings, leading to false readings or system malfunctions.

Tip: Always check and clean electrical connectors and mounting surfaces to ensure optimal sensor performance after repairs.

3. Understand Recalibration Requirements

Each manufacturer has a different process for recalibrating ADAS systems, often requiring specialized tools and training. If your shop offers ADAS recalibration, it can provide a high-value service while reducing customer downtime.

Profit Opportunity: ADAS recalibration services can range from $300 to $600 per vehicle. Shops investing in proper recalibration training and tools can retain this business instead of sending customers to dealerships.

Solution: SUN Collision’s work package feature automates repair processes, ensuring recalibration steps align with OEM specifications.

4. Communicate ADAS Limitations to Customers

While ADAS technology continues to improve, systems still have limitations—especially in low-light conditions and bad weather. Some vehicle owners may not fully understand these constraints, so it’s important to educate them after repairs.

Camera-based sensors may be less effective at night unless equipped with adaptive low-light technology.
Heavy rain, snow, or ice can interfere with radar and sonar sensors, leading to false alerts or missed obstacles.
Some sensors may need additional recalibration if the vehicle is wrapped, repainted or modified.

Verify ADAS Alerts and Notifications After Repairs

Many drivers rely on ADAS notifications to detect potential hazards. If a vehicle’s alerts continue to trigger incorrectly after repairs, the system may need recalibration or sensor replacement.

Best Practice: Always test ADAS functions and document any recalibration steps before returning a vehicle to the customer.

Don’ts for Auto Body Shops Working with ADAS Sensors

1. Don’t Modify or Replace Vehicle Parts Without Checking Sensor Placement

Body modifications such as installing aftermarket bumpers, grille guards, or light bars can interfere with ADAS sensor performance. Before making any changes, technicians must confirm how modifications will impact system functionality.

Solution: Leverage SUN Collision’s OEM repair data to verify sensor locations before replacing or modifying any parts.

2. Don’t Overlook ADAS System Updates

Modern vehicles rely on software and firmware updates to keep ADAS features functioning correctly. Skipping necessary updates can lead to system failures and potential liability issues.

Tip: Regularly check SUN Collision’s OEM data for the latest Technical Service Bulletins (TSBs) and software updates.
