GDS2 Transitioning from TIS2Web to Techline Connect

Techline Connect is quickly becoming the source for all diagnostic applications in the dealership service department. As part of the transition to Techline Connect, GDS 2 is now being removed from TIS2Web in phases. (Fig. 1) Dealerships that are not currently using Techline Connect are encouraged to begin doing so as soon as possible.

Like other tech companies that do not support older, out of date applications, GM cannot continue to support TIS2Web, which is based on legacy technology and outdated security applications. In addition to GDS2, other diagnostic features will be removed gradually until the full retirement of TIS2Web in mid- to late-2021.

Techline Connect supports all diagnostic tools available in TIS2Web and all development of future capabilities going forward will be focused on enhancing and expanding the Techline Connect experience.

Installing Techline Connect

Techline Connect is available for download both in GlobalConnect and through TIS2Web.

In TIS2Web, select the TLC tab. Go to TLC Download Page and download the Techline Connect Installation package. (Fig. 2)


In Global Connect, go to the App Center and look for the Techline Connect tile (icon). (Fig. 3) Select the ‘Launch’ option to access and download the Techline Connect Installation package.


Using GDS2

When GDS2 is removed from TIS2Web, users will no longer see the GDS2 tab in TIS2Web and will not be able to access, update or execute GDS2 through TIS2Web.

Techline Connect should be downloaded for access to GDS2. The installation of Techline Connect will remove the GDS2 desktop icon.

GDS2 can be accessed on the Techline Connect dashboard or in Standalone mode, which provides the capabilities of GDS2 while offline.

To use GDS2 offline, run Techline Connect as you normally would. From the log-in screen, select the Enter Standalone Mode button. (Fig. 4)
