MDI Manager and Data Bus Diagnostic Tool Software Updates


New diagnostic software updates are now available or being rolled out to GM dealerships across the country.

MDI Manager

The new MDI Manager software includes updates for the future CAN FD protocol that is necessary for the next generation of GM vehicle architecture.

CAN FD (CAN with Flexible Data-Rate) is an extension to the original CAN bus protocol. It’s designed to make the Controller Area Network (CAN) faster, extending the useful data length from eight to 64 bytes for significantly higher data transmission rates.

The new software is being released through a staggered rollout to GM dealerships. The initial rollout included all GM dealerships in Michigan and Ohio. Additional dealers will be added every Monday, with completion of the rollout in October.

A user will be prompted to install the MDI/MDI2 Manager software when clicking the SPS or GDS2 icon in TIS2Web. (Fig. 6) It is recommended to update all MDIs and Service computers at the same time to avoid incompatibility issues.


Data Bus Diagnostic Tool also recently began distributing Data Bus Diagnostic Tool software update version 1.30.923 through TIS2Web. The update allows the tool to simultaneously monitor up to three dual-wire CAN busses as well as corrects some Device IDs. To download the software, click the GDS 2 icon on the TIS2Web home page.
