05 CTS V ecm read problem
Wondering if anyone has encountered this problem before. I went to do a read from an 05 CTS V p59 ecm and it could not find a VIN in the computer and asked me to manually input it which I have never had to do before. After doing this the read moves at incredibly slow Speed and shows time estimates bouncing from 100 to 800 minutes. Anyone seen this issue before or know the solution? Thank you in advance for any help.

Did you pull the Nav/Radio Fuse before trying to read/write? I have an 04 and for some reason that seems to be the trick on these. Never ran into your problem though. FYI, the fuse you need to pull is under backseat driver side.
