Procedure 2:
1. Send a RequestDownload message with a valid dataFormatIdentifier and unCompressedMemorySize
parameter value without unlocking security, verify the proper negative response message ($7F $34 $22,
sequence error) is sent.
2. Perform security sequence. Send a RequestDownload message with a valid dataFormatIdentifier and
unCompressedMemorySize parameter value without previously activating mode $28, and verify the proper
negative response message ($7F $34 $22, sequence error) is sent.
3. Perform security sequence. Send a DisableNormalCommunication request message, verify positive
response. Begin TesterPresent message periodic. Send RequestDownload message with a valid
dataFormatIdentifier and unCompressedMemorySize parameter value. Verify that negative response
message ($7F $34 $22, conditions not correct) is sent (because programming mode not active).
4. Perform a valid download of data with the download scheme defined, using service $28, $A5, $27 (if
applicable), $34 and $36. While the ECU expects more data to be downloaded with the service $36
transmit a service $34 request message and verify the negative response message ($7F $34 $22,
conditions not correct) is sent.
5. Send a request message with less than the required amount of data bytes and verify the negative
response message ($7F $34 $12) is sent.
6. Send a request message with more than the required amount of data bytes and verify the negative
response message ($7F $34 $12) is sent.
7. Perform security sequence. Send a DisableNormalCommunication request message, verify positive
response. Begin TesterPresent message periodic. Enable programming mode with the $A5 service. Send
RequestDownload message with the correct number of data bytes and an invalid dataFormatIdentifier
parameter value. Verify proper negative response reject message ($7F $34 $12, sub-function not
supported) is sent.
