Techstream Lite allows Techstream diagnostic software to run on your PC (see minimum PC requirements) to service Toyota, Scion, and Lexus vehicles. Techstream Lite is an 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.
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. You must have an active professional level subscription to access the calibration files.

It is possible to permanently damage a vehicle controller during the flash reprogramming process. It is especially important to understand that once started, the reprogramming process must not be interrupted, reprogramming devices must not be disconnected and PCs must not be allowed to go into Standby, hibernation or similar power management modes. The information provided herein is intended expressly for use by qualified professional automobile technicians. To prevent damage to your customer’s vehicle and ensure safe service practice, read these materials completely and thoroughly before servicing the vehicle and be sure to follow all instructions.
Some reprogramming operations require writing the VIN back into the module. Please refer to service information before beginning any reprogramming operation to determine this need and to download the necessary software tool.
