Tech Tool (TT) is a tool that supports the repair and diagnostic process. It was developed to make repair shop tasks easier and more efficient. TT can be used in the repair shop, out in the field, at the roadside, or during test drives. TT is a diagnostics application that covers the whole repair process through the use of plug-ins. With TT you can diagnose, test, calibrate, and program a product. A product could be a vehicle, engine, or a machine. TT also provide functions for updating the tool, communication with the product, and other external applications. The set of plug-ins, user authorizations, and available languages is adjustable to provide every user with what they need.

The basic workflow in Tech Tool is the same for all products:
 • Identify a product.
 • View information history.
 • Diagnose a selected product.
 • Test a selected product.
 • Program a selected product.
 • Calibrate a selected product.
