TIS Techstream Scantool

  Toyota’s original scan tool was based on Vetronix’s Mastertech platform and was put in service in 1993. In the spring of 2007, Toyota shipped their new PC-based scan tool, called TIS Techstream, to its 1750 North American Toyota/Scion dealers.

This new OEM scan tool is a great example of how to leverage a tool’s capabilities by using existing industry standard hardware and technology. As shown in the image to the left, the TIS Techstream is made up of three main parts.


The PC
At the core of this tool is a Panasonic ToughBook 19 computer. This computer has become an industry standard among ruggedized computers. Some of the more noted ruggedized features are: full magnesium alloy case, moisture and dust resistant keyboard and touchpad, sealed port and connector covers and a shock-mounted removable hard drive.

The Backpack
The ruggedized ToughBook is further toughened up by placing it into another frame (backpack) that adds big corner bumpers and additional padding. The backpack also holds the Vehicle Interface Module (VIM) and a charging module to provide power to the computer from the 12v source that is available from the OBD-II data link connector.

The Docking Station
When not in use, the computer/backpack unit is placed in the docking station for charging. The backpack can also be locked to the docking station for security.

Service information from Toyota’s Technical Information System (TIS) is delivered to the scantool using industry standard wireless network technology. Techstream will automatically notify you if a PCM update is available for a car being scanned. You are given the option of reading the TSB that addresses the details of the PCM software update and updating the software if you choose. The TIS Techstream integrates a robust OEM level scantool, a service information system, and PCM reprogramming into one bayside tool!
