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SDGM, access via 6 and 14 for system primary HS GMLAN diagnostics using a DMM or other means than the scan tool is no longer valid, since each DLC network loop at the SDGM is configured with two 60 resistors in series, as shown in the Figures above for 2019 Cadillac XT4 and other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.
