Hey everyone, I am having a issue with a new tune throwing a brake assist light C0131-5A - ABS Pressure Circuit Plausibility Failure.
I have written the old ECM tune and left the new TCM tune alone and the code doesn't appear. I have swapped everything over from the old tune to new other than the Fuel, Spark, Idle, and Air flow and the code still appears.
I figured maybe the torque desired was to high and setting the code but its not.
Any Ideas? Thanks!
