2007 1500 4x4, just behaves like it has no abs. The light comes on when the key is turned. Very slippery today and it just doesn’t trigger. Background info, I put a used pcm in this truck because a coil driver died in the original. I bought the truck with the bad pcm so I can’t comment on how it worked prior. Input would be great. Thanks

I’m going to say yes cause it’s been a while (3yrs) and I think I recall when I first swapped the new pcm in I could actually see both the truck vin and the donor pcm vin on a scan tool. I paid someone to marry the modules. He used my existing skim. I have no other functionality issues.

Mildly curious about trying the original pcm to see what happens.

I actually don’t have the answer to that. The best I can do at this point would be to check the pcm’s are the same part numbers. Not to say the same pcm can’t have a different flash.

At the time I had no clue not all 2007 1500 4x4 rams had the same abs.

If abs is the only incompatibility, I have no problem living with it as it does nothing annoying other than not work.

If I am overlooking something simple then I would like to make it work.

I got the truck for next to nothing because it was diagnosed as needing a head gasket. All it needed was a pcm and a water pump.
