cannot read pcm

[slickfitz]

Hey I have a trinity with all the updates had it in my 2006 300c returned to stock to test out new options in my 2006 dodge ram hemi.... had fun with that!! took the trinity put a tune in ..wife said lights came on (bas esp)
soo plugged tuner in to read codes..sometimes it would read ..other times it would say cannot read make sure key is on..soo finally returned to stock to bring so I can bring to dealer ..but now the trinity won't read either pcm on my ram or 300c

Whats the exact message it gives you? The keys are ON? Did you try removing and reinserting the cable into the Trinity? Its a really tight connection that doesn't always click in.

I'm not sure of exact reading....I'll post later but it's along the lines of cant read pcm make sure key is on vehicule not running
gives you option to retry ..do that 3 times I believe then it says unplug tool and try again ...reads the vin tho

Hey Mike plugged back the trinity in the 300c and it worked I made sure cable was tight..don't know if it was that I used my wifes key..would that cause it? I'll try it in the ram ..just weird cuz I must of tried 5-6 times in both..
