Table C24: Definition of Subnet Config List Mid Speed dataIdentifier
DID Description
R/W Data Type
Len
$BB 
Subnet_Config_List_MidSpeed (SCLMS)
R/W
BIN
≥ 1
This DID contains the SCLMS. Each bit represents one ECU (with unique Diagnostic Address, see
Appendix D) that can exist on the mid speed 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.
Example: 
The example assumes that the ECC occupies bit 7 of byte 0 and the TMS occupies bit 0 of
byte 0.

Table C25: Definition of Subnet Config Lists for Non-CAN Buses 1 - 2 dataIdentifier

Subnet_Config_List_NonCan 1 - 2 (SCLNC 1/2)
R/W
BIN
≥ 1
$BD These 2 DIDs are allocated to contain subnet config lists for data links not directly connected to the DLC
but contain a member node which is diagnosed via a GMLAN subnet. The tool can write the
configuration information of the non GMLAN network into the GMLAN node which is also present on the
non GMLAN network, for the purpose of network management of the non GMLAN network. Examples of
this may be a GMLAN node that is also an entertainment ECU that is part of a MOST network.
Each bit represents one ECU (with unique Diagnostic Address, see Appendix D) that can exist on the
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.
