FlashScanV2. been working with a 2010 cab/chassis truck (wrecker)..as of now its 182,835 miles....been receiving tunes from a known diesel tuner. the last tune had some DEF DTC's still enabled, so we got ahold of him to ask him to send a new one. Wrote the patch to the ECM..( I had also been told that you didn't have to patch every time. BUT if I didn't patch and just tried to write the tune, it would say "Controller Device Mismatch".) anywho...wrote the patch, and then started the actual tune write..it went normal and then right where it would finish up and sound off the chime, instead of saying "Script finished successfully" it said "Transfer Suspended"... after that its been a no-start. We cant figure it out, we don't really mess with the new stuff usually. More of the Duramax stuff. but this truck has been a pain...ANY help would be appreciated.. even if its just people confirming if the ECM is junked..thanks for reading. Everything is up to date BTW.
