Note: 
No response is sent by the SPS_TYPE_C ECU at this point.
ReportProgrammingState service $A2 request.
•
Use service $A2 to determine which ECUs are programmable and which ECUs are SPS_TYPE_C.

Note: 
No response from the non-programmable ECUs because a functional request for a service which is not
supported results in no response message being sent.
At this point, the tester would request ECU ID information using mode $1A in order to determine which files are
needed for the programming event. This step is not shown in this example.
Next step, read seed.
•
Use service $27 to read the seed from the programmable ECUs.
