3. Send a request for this service to the ECU when it has boot software and operational software present
(no calibration data) and verify the proper response.
4. Obtain a controller with default calibrations programmed in (only applicable if the ECU supports $A2
response $03). Send a request for this service and verify that the ECU sends the $E2 $03 response.
5. Create situations for each of the memory failure response codes that the ECU supports and verify the
proper response.
Procedure 3: 
(For SPS_TYPE_C ECUs when operating out of boot software.)
1. Send a request for each diagnostic service supported in the ECU (except services $28 and $A2) and
verify that no response is sent.
2. Send an all nodes request for service $28 and verify no response. Wait for a positive response from all
ECUs (that have stored permanent diagnostic CAN Identifiers) and then send a request for $A2 service.
Verify that a positive response is sent using the ECU’s SPS_PrimeRsp CANId ($3xx).
3. Repeat step 2 for each valid positive response value (programmedState) supported by the ECU when
running out of boot, and verify the proper positive responses for each case.
4. Send an all nodes request for service $28 and then repeat step 2 of Procedure 1 (if applicable).
5. Repeat step 2 of this procedure. Send TesterPresent $3E messages at least once every P3
C 
ms while
requesting the other supported diagnostic services with the SPS_PrimeReq CANId ($0xx). Verify that the
ECU continues to respond properly using the SPS_PrimeRsp CANId ($3xx). Stop sending TesterPresent
($3E) messages and wait P3
Cmax 
ms. Verify that the ECU no longer responds to diagnostic requests.
8.16.8 Tester Implications. 
For SPS_TYPE_C ECUs, the tester must first send a mode $28
(DisableNormalCommunication) request to all nodes, AND verify all normal communication has ceased before
sending the mode $A2 request. Sending the mode $28 to all nodes first ensures that there will be no conflicts
with normal message CAN Identifiers and any of the SPS_PrimeRsp response CAN Identifiers.
The tester must send TesterPresent ($3E) messages at an interval less than P3
C 
to keep an SPS_TYPE_C
ECU actively responding to diagnostic service request messages.
