asTech Rules Engine Case Study #3

Using the 2016 Honda Civic to Demonstrate the Importance of Verifying the Accuracy of Aftermarket Scan Tools

PLANO, TX – Oct 3, 2023 asTech, a Repairify company and the global leader in remote diagnostics, calibrations, programming, and automotive intelligence for the collision and mechanical repair industries, has released its third Rules Engine case study from the asTech insights Institute.

This case study demonstrates the data-driven verification process of the patented and proprietary asTech Rules Engine. It shows why it’s the only verified way to properly determine if an aftermarket scan can be trusted on a specific vehicle.

What Repairify’s Technicians Did

To develop its patented Rules Engine, Repairify performed tens of thousands of vehicle scans against the active car parc and engaged in extensive research to identify which of the top aftermarket scan tools yield the same results as the authentic OEM tools.

During their research, Repairify technicians post-scanned a repaired 2016 Honda Civic using the authentic OEM scan tool and discovered two diagnostic trouble codes (DTCs). They then immediately post-scanned the same vehicle with a leading aftermarket tool, designated in this case study as “Brand B.”

What the Aftermarket Tool Found

Conventional wisdom is that any aftermarket tool should be able to thoroughly scan a common seven-year-old vehicle, such as this Honda Civic, without issue. However, the aftermarket diagnostic scan performed using Brand B’s tool only returned one of the two DTCs established by the authentic OEM tool.

As with asTech’s previous case study regarding a 2021 Jeep Gladiator, this shows that conventional wisdom regarding aftermarket scan tools can be unreliable. It can lead to using inaccurate scans and returning a vehicle that is not properly repaired to OEM standards.

What This Means for Shops and How the Rules Engine Helps

The Rules Engine recommends a choice of asTech certified scan tools to repairers for each specific (down to the trim level) vehicle they’re working on:

  1. An authentic remote OEM diagnostic scan through asTech’s patented technology.
  2. A certified OEM-Compatible aftermarket scan. This is a scan that has been verified and warrantied to provide results that are equivalent to the authentic OEM tool scan.

For this 2016 Honda Civic, a shop using the Rules Engine would only be able to use an aftermarket scan verified as OEM-Compatible. Brand B’s scan would not be an option as it would be deemed “unverified.”

In addition, shops that are part of the Honda collision repair network are required to exclusively use authentic OEM tool scans for Honda vehicles. For situations like this, the asTech Rules Engine is customizable. It allows shops to set special rules such as only allowing an authentic remote OEM tool scan to be used when any Honda vehicle is connected to an asTech device.

The Rules Engine’s data-driven verification process and flexibility gives shops the confidence to know they are selecting the best scan for the vehicle they’re repairing.

About the Rules Engine

With tens of thousands of vehicle scans and extensive research, asTech, driven by Repairify, is continuously developing its patented and proprietary database of authentic OEM and high-performing OEM-Compatible aftermarket scan tools to recommend the most accurate and cost-effective scan tool option, every time. When an OEM-Compatible scan isn’t available, the Rules Engine recommends the same remote OEM diagnostic services that customers have come to know and trust.

Repairify continues to augment, edit, and update the Rules Engine database via ongoing research being conducted by its engineers globally. This database represents the most comprehensive dataset for comparison analysis on a global scale. Select individual vehicle testing results can be made available to customers for review.

  • To build the asTech Rules Engine, Repairify’s Research and Development Team scanned tens of thousands of vehicles from different years, makes, models, and trim levels with nine of the top aftermarket tools available, then compared the results to the relevant OEM tool. Researchers used like-for-like tools on the same cars in the same day to ensure accuracy.
