New Models Using VIP Require the MDI 2

January 18, 2023

The Vehicle Intelligence Platform (VIP) electrical architecture continues to power a growing number of new GM vehicles for the 2023 model year.

The VIP architecture offers enhanced capacity and better management of complex technology. With the capability of managing over 100 computer modules, it can support active safety systems, Over-the-Air (OTA) vehicle software updates, 5G networks, enhanced cybersecurity protections and EV technologies.

GM models using the VIP architecture include:

Buick

• 2021-2023 Envision

Cadillac

• 2023 LYRIQ

• 2021-2023 Escalade

• 2020-2023 CT4

• 2020-2023 CT5

Chevrolet

• 2023 Colorado

• 2022-2023 Silverado 1500

• 2021-2023 Tahoe and Suburban

• 2020-2023 Corvette

GMC

• 2023 Canyon

• 2022-2023 HUMMER EV

• 2022-2023 Sierra 1500

• 2021-2023 Yukon

MDI 2 Required:

The EL-52100 MDI 2 is required for control module programming, configuration and setup on vehicles equipped with the VIP architecture. (Fig. 11) The MDI 1 cannot complete programming and setup procedures. Using an MDI 1 on these vehicles could result in erroneous data or failed programming events, leading to unnecessary module replacement.

Fig. 11. When a scan tool is installed, it will attempt to communicate with every control module available on the vehicle, depending on optional equipment. The tool will display No Communication for that control module if an option is not installed on the vehicle. To avoid misdiagnosing a No Communication message, refer to the Data Link References that list the control modules and the buses with which the modules communicate in the appropriate Service Information. The vehicle builds RPO codes to determine optional control modules.
