been sent, manufacturers enable counter = $00, and the vulnerability flag < $FF. Verify the negative
response ($31 - Request Out Of Range) is sent.
2. Send a $1A message with a security code required $dataIdentifier value when the manufacturers enable
counter > $00 or vulnerability flag = $FF and the security code has not been sent. Verify the negative
response ($31 - Request Out Of Range) is sent.

8.4.8 Tester Implications. 
This service can result in responses which are single frame or multiple frame
based on the DID requested. The tester should not functionally address requests for this service for a DID
which results in multiple frame responses unless it can handle sending the flow control frames to each
responding node within the allowable network timing parameters.
