Step Action
5
Send a 
DisableNormalCommunication ($28) 
request (with AllNodes CANId and AllNodes
extended address - on each link as needed).
•
This disables sending and processing of normal mode data.
•
An SPS_TYPE_C ECU does not respond to the $28 request but tracks receipt of the $28
request (in order to enable diagnostic responses after receiving the $A2 service later in the
process).
•
The tester shall not enable diagnostic responses in SPS_TYPE_C ECUs (via mode $A2) until
after it has received positive responses to the $28 request from all other ECUs on the link (as
stored in the diagnostic configuration matrix).
6
Determine which nodes are programmable using the service 
ReportProgrammedState ($A2) 
with
the AllNodes CANId and AllNodes extended address (finalization of the diagnostic configuration
matrix - on each link as needed).
•
Each SPS programmable ECU shall respond.
•
SPS_TYPE_A and SPS_TYPE_B ECUs respond with their permanent diagnostic USDT
response CANId (which falls within the reserved range of diagnostic response CAN Identifiers).
•
An SPS_TYPE_C ECU responds with the SPS_PrimeRsp CANId ($3xx where xx = diagnostic
address).
•
At this point the SPS_TYPE_C ECU would activate and accept the SPS_PrimeReq ($0xx)
CANId as a diagnostic PTP request CANId (where xx = diagnostic address).
•
MSSC ECUs shall only respond to the $A2 service on the subnet where they support
programming (MSSC ECUs shall only be programmable on one subnet – see 4.3.4.

Retrieve necessary ECU ID and vehicle option content (e.g., engine type) information from the
programmable node(s) (using
