ABS code 54 - Shorted Dump Coil Rear

[kevaug]

hi I have a 2004 Ram 1500 4x4 SLT 4.7L 5 speed manual tran
I just received a used programmed PCM and my ABS light is flashing.
my scan tool is reporting an ABS code 54 - Shorted Dump Coil Rear
and a ABS code 55 (which i cant find the explanation of that anywhere)

Does anyone know how to test or the location of this
Shorted Dump Coil Rear?
thanks

Did you have this problem before you installed the used PCM?

No I did not. I had a high idle which the new PCM did solve but I think this ABS code
is because it might not be programmed properly.
I had to send it back once already because they had the incorrect VIN # in the first unit they sent me.
Ive been trying to find an answer and heard that this code may apply to an air assisted braking or air suspension vehicle which mine has neither.
