Techstream Lite allows the Techstream diagnostic scantool software to run on your PC (see minimum PC requirements) to service Toyota, Scion, and Lexus vehicles. Techstream Lite is the inexpensive alternative to the full TIS techstream system and provides factory level support for Toyota/Scion/Lexus vehicles.
Techstream Lite supports DLC3/J1962 based diagnostic functions on 1996 and later Toyota, Scion, and Lexus vehicles marketed in North America. You must have an active professional level subscription to use Techstream scan tool software.
Toyota, Scion, and Lexus ECUs can be reprogrammed using Techstream Lite. Available ECU updates are specified in applicable Technical Service Bulletins (TSBs), which can be accessed with a subscription to this website.
