InitiateDiagnosticOperation ($10) 
request with a sub-parameter value of 
$02
(disableAllDTCs) 
using the AllNodes request CANId and the AllNodes extended address.
•
This step ensures that nodes that poll the CAN controller do not set DTCs if they do not process
the mode $28 request (in the next step) before they could possibly set signal supervision
failures.
17
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 a $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 (via mode $A2) in SPS_TYPE_C ECUs 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).

Step Action
18
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 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 its SPS_PrimeRsp CANId ($3xx where xx = ECU
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.)

Verify that the tester is connected to the correct vehicle - the same vehicle from which the seed was
retrieved (e.g., use the service
