Calterm question, reflash failed.

[MattB]

Hi everyone! Hope everyone has had a good week. Happy Friday! I have a quick question, I was putting a calibration in a CM871 ECM (PN P3684275-RX) with Calterm 5.7. Before reflashing the ecm, i made sure to unlock ecm. The reflash itself took 5 minutes, but at the end it failed.

ECM, TIS, & application are all checked ✔️ on Save and Restore settings.

Access level group is set to CMI

The message I had said " Save changes operation failed as module is secure and tool family is Engineering [TOOL_PERMISSION_DENIED] "

I figured I might as well try using Calterm 3, but ran into same message.

Ecm is locking after every failed reset, not sure if that matters; I've never looked to see if it automatically locks once you finish reflashing.

Never ram across this on any other ecm.

Thank you all for reading, I'm curious as to what I'm doing wrong @
I took a look under the help index, but couldn't find where they put the error messages.

Hi everyone! I got it figured out thanks to Rollingsmoke, the cal I was trying to put in was the issue. Used a different calibration and it flashed successfully:)
