The Importance of Pre and Post Scanning in ADAS Calibration: Where Does Your Company Stand?

The topic of Advanced Driver Assistance Systems (ADAS) is becoming increasingly important in the automotive industry. As vehicle technology evolves, the repair processes have to adapt accordingly. One aspect of ADAS repair that has come under focus is the practice of pre and post scanning during vehicle repair. But how many companies are actually making this a standard part of their procedure? Let’s delve into the statistics.

The Current Landscape

Based on recent survey data in an Instagram poll from, here is the breakdown of how often companies perform pre and post scans on vehicles they repair:

Always: 59%

Sometimes: 23%

Never: 18%

This reveals some interesting insights.

The Good News: Majority are Compliant

59% of companies are already making pre and post scans a routine part of their repair process. This is an encouraging statistic as it demonstrates a high level of compliance with manufacturer guidelines and industry best practices. By scanning before and after the repair, companies can ensure that all systems are working as they should, thereby increasing vehicle safety and customer satisfaction.

The Concern: Lagging Behind

However, the data also reveals that 41% of companies are not always conducting these scans. Of this group, 23% are doing it “sometimes” and an alarming 18% “never” perform these scans. This opens up a variety of risks including potential liability issues, compromised safety, and customer dissatisfaction.

Why Pre and Post Scanning is Crucial

Diagnostic Insights

A pre-scan provides an initial diagnostic snapshot of the vehicle’s systems. This enables technicians to understand what repairs are needed, and if any ADAS components are affected. 

Calibration Verification

Post-scans are essential to verify that all systems are functional and calibrated correctly after repairs are completed. For vehicles with ADAS, a post-scan ensures that safety features like lane-departure warnings or automatic emergency braking are working correctly.

The Bottom Line: Best Practices are Non-Negotiable

With the advent of more technologically advanced vehicles, adhering to best practices isn’t just a recommendation—it’s a necessity. In addition to meeting manufacturer guidelines, consistent pre and post-scanning can also elevate a company’s reputation for quality and safety.

Moving Forward

The industry needs to aim for a 100% compliance rate for pre and post scanning during ADAS calibrations. Automotive repair companies should invest in training and equipment to ensure they’re not part of the 41% lagging behind in implementing this essential best practice.

In this competitive landscape, staying updated with the latest technologies and practices is not just a way to get ahead—it’s a way to stay relevant. 

Does your company fall into the 59% that always conduct pre and post scans, or is there room for improvement? Either way, it’s a question worth considering as we drive towards a safer, more efficient automotive future.
