8.16.4 Supported Negative Response Codes (RC_). 
The following negative response codes shall be 
implemented for this service. The circumstances under which each response code would occur are 
documented in Table 162.

8.16.5.1 ReportProgrammedState Positive Response Example. 
In the following example (Table 163), it is assumed: 

There are two SPS programmable nodes on the link. 

The $28 service has already been activated. 

Node 1 is a programmable node that is fully programmed (SPS_TYPE_A) with a USDT physical response 
CANId of $641. 

Node 2 is an SPS_TYPE_C ECU that has no operational software or calibration data programmed. The 
diagnostic address of this node is $80 (thus the SPS_PrimeRsp CANId shall be $380 and the 
SPS_PrimeReq CANId shall be $080). 

TesterPresent messages are sent (but not shown in the example).
