Case Study: asTech Rules Engine #5

Nov. 20, 2023

In this Rules Engine case study, the asTech Institute demonstrates that, regardless of the age or popularity of a vehicle, there is no guarantee an unverified aftermarket tool will provide a fully comprehensive and accurate scan. To ensure a safe and proper repair, shops must utilize empirical data that verifies they’re choosing the correct tool scan for a particular vehicle.
What Repairify 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 authentic OEM tools.
Repairify technicians post-scanned a repaired 2017 Toyota Camry using the authentic factory scan tool and discovered two trouble codes within the antilock braking system, including one code related to traction control.
The vehicle was then immediately scanned using leading aftermarket tools to compare the results to the scan from the authentic OEM tool.
What the aftermarket tool found
The common convention is that most aftermarket scanning solutions should be able to identify all modules on a five-year-old Toyota Camry – one of the most popular vehicles on the road. But when one aftermarket tool brand, “Brand A”, was used to scan the same vehicle, it identified just one of the two trouble codes on the 2017 Toyota Camry’s ABS system.
What this means for shops
Even for vehicles as popular as the 2017 Camry, it is still possible for aftermarket tools to miss codes on some of the most common modules (like the ABS system) in circulation.
Like it was shown with the 2016 Honda Civic case study and asTech’s other prior case studies, the age and popularity of a vehicle doesn’t matter. Without data to verify a scan’s accuracy, there is no guarantee that an aftermarket scan will match the performance of an authentic OEM tool.
How the Rules Engine helps
The Rules Engine recommends a choice of asTech-certified scan tools to repairers for each specific vehicle they’re working on, down to the trim level:

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

With the Rules Engine, shops would have the confidence in knowing that if they decided to use an aftermarket scan for a 2017 Camry, it would be verified as OEM-compatible.
To ensure a safe and proper repair, a shop needs to use the proper scan. To ensure they use the proper scan, shops need empirical data. The Rules Engine provides shops with the only data-backed system to verify that they’re using the best scan for the vehicle they’re repairing.
