Negative response code 0x70 indicates that a requested upload or download was not accepted. It does not explain the entire underlying fault on its own.

Interpreting the evidence

Review the module identity, selected file and previous steps in the authorised programming log. Check whether the tool met the required session and vehicle conditions. Establishing where the process stopped helps distinguish a rejected request from a transfer that began and then failed.

Keep this evidence

Send the complete log and software identification, with confidential account data removed.

Avoid trying unrelated files to force acceptance. Recovery depends on the exact hardware and supported programming route.
