Tech2 Tool Remote Mode ECU TIS2000 Calibration Update

Here is the step-by-step instruction on programming GM (General Motors) ECUs with Tech2 scanner and SPS (Service Programming System) application in TIS2000.

This article is an overview on how to use the GM Tech 2 Scan Tool to perform GM SPS Programming of calibration file updates for the ECU or any programmable module firmware on the vehicle such as the EBCM, TCM, or Radio that you may want to reflash. Of the different reflash programming approaches, this first video covers Remote Mode between the Tech2 and the Techline terminal PC running TIS 2000. This procedure applies equally to the genuine Tech2 manufactured by Vetronix, HP, or Bosch as it does to any clone or knock-off model from China.

Warning: Pay very close attention to the instructions around power cabling and battery readiness as a power fluctuation during an SPS programming procedure can permanently damage a controller module.

TIS2000 was deprecated by GM in early 2008, but was once the primary Techline Information System approach delivered to dealers via DVD media on a quarterly basis. Today we would use the subscription based TIS2Web as part of the ACDelco TDS server based offering to accomplish many of the same tasks, although Tech2 Remote Mode is no longer supported or offerred by TDS for newer vehicles.

Note: be sure your USB to serial adapter device driver is configured for 115200 speed on Windows using Device Manager and that you set the COM port it is assigned to within TIS2000 for communication to be successful between the PC and the Tech2.

Applicable to OBD2 model years 1996 thru early 2008 only, and for all makes under General Motors such as Chevrolet, Buick, GMC, Cadillac, Oldsmobile, Pontiac, Hummer, Saturn, Opel, Vauxhall, and Saab.
