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
