Connectivity is dependent whether the network being accessed, is a primary or isolated network and the generation of SDGM comes into play with increased security of Generation 3 SDGMs, effectively "slamming the front door" closed to previously accessible networks, using the DMM and DBDT. Knowing that there are two 60 resistors wired in series through terminals 6 and 14 connection from the DLC at the SDGM, measuring 120 , validates the integrity of the circuit to the SDGM from the DLC. These modules would be accessible using traditional testing means in the event of a failure. Whether Global "A" or "B" alone, does not define the diagnostic approach. Without using the tool, the bus schematics and RPO codes will provide some clues, but the DBDT is ready at hand. Clicking on the "DLC Pin" button will put the modules in an organized list from Pin # 1 as shown in Figure 2.

Most current platform GM vehicles are still Global "A", with only the 2020 Cadillac CT5 being Global "B". Miscellaneous Unclassified. The BCM 1 and BCM 2 fuses are what the BCM uses to feed power to circuit 5986. %%EOF Gateway Module (SDGM) may report "Crash Sense Failed" and the 300v Hybrid Battery . Beyond this it is basically down to performing some routine electrical circuit tests with our tools of preference. It is located in the section: Diagnostic Overview, Starting Point, and Programming / Programming and Setup / Repair Instructions. Body Control Module (BCM) Left side of dash. HS GMLAN has lived at pins 6 and 14 as the primary high speed network, as mandated and continues to reside there right through Global "B" network introduction. However, on the vehicle side of the SDGM the networks still remain in the same configuration with end of line termination resistors inside modules, or as separate components. With changes to a 3rd generation SDGM, access via 6 and 14 for system primary HS GMLAN diagnostics using a DMM or other means than the scan tool is no longer valid, since each DLC network loop at the SDGM is configured with two 60 resistors in series, as shown in the Figures above for 2019 Cadillac XT4 and other represented models. More information here: gm.com/masthead-story. Write this number to the right of the first one. THANK YOU VERY MUCH for taking the time to post this.
