$EA Subnet_Config_List_GMLANRearObjectExpansionBus (SCLGROEB)
R/W
BIN
≥ 2
This DID contains the SCLGROEB.
Each bit represents one ECU (with unique Diagnostic Address, see Appendix D) that can exist on the
expansion bus subnet. A logic “1” indicates that a given ECU is present on the vehicle. The bit mapping
of ECUs must be documented in a CTS, SSTS, or supplemental diagnostic specification.
