Most basic scan tools or systems only decode SAE-standard diagnostic trouble codes (DTCs). The number of controllers varies by car model, but there are generally 20-50 different controllers on a new car, and 10-30 controllers on a new heavy truck. These controllers will run and manage the operation of different systems on a vehicle. In reference to the ECU, TCU, or hybrid controller, the controller in this case essentially means computer. Basic diagnostic tools provide emissions-related data only. Basic diagnostic scan tools or systems, sometimes referred to as generic scan tools, typically can only read data from the engine control unit (ECU), and possibly the transmission control unit (TCU) or hybrid controller. This article will focus on aftermarket diagnostic scan tools.Īftermarket scan tools fall under two different categories: basic and advanced.

This cost can add up, especially when a fleet needs to have one license for each make serviced in the shop.Īftermarket diagnostic scan tools are created from data licensed through each OEM, combined with extensive test and validation work done by the tool manufacturer. However, OEM scan tools are not as flexible as aftermarket tools and usually cost quite a bit more. In general, these tools have the best support for a given manufacturer’s vehicles.
These tools typically require a J2534- or RP1210-compatible interface and run on a Windows PC. Original equipment manufacturer (OEM) diagnostic scan tools are becoming increasingly available to shops and individuals through time-based licensing directly from manufacturers. A quick review of the general differences between basic versus advanced diagnostic systems may help clear up some of the confusion.

Questions from professional technicians, fleet managers, and consumers often come up about the difference between the vast array of different automotive and heavy duty scan tools available on the market. As vehicles on the road today become increasingly more reliant on computers and data, diagnostic tools have evolved as part of the frequently used tools for shop technicians.
