$0537 lb7
I think the ECM we are working with is bricked but wanted to get some insight before we replace it. The attached pictureshows the following:
Left - Tune that was read off of the ECM (was tuned by someone with unknown software)
Center - Tune file that we flashed on, VIN number matched, OS was different from read but VIN was matched.
Right - Corrupt VIN?, NA Serial, corrupt BCC?
We initially flashed the truck 6/28/2015 (V8 and 7.5 were up to date but not sure what versions), made a revision and flashed it a second time, no issues, files set to Auto-lock. Customer gets a built trans and wants some changes and we attempted to reflash (early September 2015, updated pre-release V8.2.2.285, V7.5.7 build 292, firmware up to date) and got $0537 on the first attempt... Remove radio and abs fuses, same issue. Attempted alt keys etc., no go. At this point we took the screen shot on the right. Customer mentioned that a Tech II was attached but only to check balance rates.
Is there a chance to recover this ECM? Possible causes? Any insight would be appreciated. Thanks.
