I have a 2006 Cummins that I cannot connect to.
I use just the V2 to scan for codes and it fires up just fine I go and try and scan for codes and it says: Error $0280 cannot connect to ECM
I try and run 7.5 scan and it will not let me do any scanning. I select the cummins 849 ecm and it says Cummins on the lower part of the screen then 10-15 seconds it switches to Generic but it has the correct VIN #.
I bought the $450 Cummins tune unlock.
The V2 is black and I bought in 2007.
I am running the latest update.
I can Scan the truck with a Snap-On Solus just fine.
Thanks
Bob
