As Service Programming System (SPS) events become larger in size and more frequent for all GM models, it\u2019s important to ensure the most reliable connection method to the MDI 2. (Fig. 1) With the proliferation of wireless devices in the dealership, wireless interference has become very common and difficult to remediate. As a result, beginning June 23, 2025, all SPS events will require a hard-wired connection from the PC to the MDI 2 using either a USB or ethernet connection. An ethernet connection will provide the best overall performance.<\/p>\n

SPS Message<\/strong><\/p>\n

To accommodate the change to a required hard-wired connection, it\u2019s important to avoid starting Techline Connect with a wireless connection to the MDI 2. If a wireless connection is being used for diagnostics, then a switch is made to SPS, the MDI 2 must be fully disconnected manually from the wireless connection using GDS 2. Otherwise, a full reboot of Techline Connect will be needed to break the wireless connection. Plugging in a USB cable while connected wirelessly also will not break the wireless connection.<\/p>\n

When a hard-wired connection is not used while attempting to program a module, SPS will display a message that a wired connection is not detected. (Fig. 2) If this message is shown, connect the MDI 2 using a USB or ethernet cable and relaunch SPS before attempting the programming event again.<\/p>\n

Quality Cables<\/strong><\/p>\n

To ensure successful programming events and reduce the potential for errors, proper OEM service tool equipment, or comparable quality cables and adapters, should be used. Recommended OEM cables are available through the GM MDI website operated by Bosch, including:<\/p>\n
