Introduction to Toyota TIS Techstream

Toyota TIS Techstream is the replacement for the Diagnostic Tester. It combines the functionality of TIS and the scantool into a single portable device. With TIS Techstream, technicians can simultaneously view and analyze on-board vehicle data, browse relevant TIS service documents, and reprogram vehicles all from the driver's seat via a wireless connection to TIS.

Scantool Diagnostics

TIS Techstream offers full support for 1989 to current vehicles marketed in the United States. Periodic software updates are available to support new models. TIS Techstream provides quick and easy access to all available systems on the vehicle as well as a one-touch vehicle status report (Health Check).

Vehicle Reprogramming

Toyota, Scion, and Lexus ECMs can be reprogrammed using the TIS Techstream scantool. The ECM reprogramming function is only available with the authentic TIS Techstream software, which runs on the aforementioned scantool. TIS Techstream software version requirements are specified in applicable Technical Service Bulletin (TSB) or Service Communication (SC) documents, which can be accessed with a subscription to this website. Older documents may state to use the Diagnostic Tester as the required tool, but TIS Techstream is now the replacement and can be used for all Toyota, Scion, and Lexus vehicles marketed in the United States.
