Help Needed Dtc p 0603

[Jim Fulton]

I have a superchips programmer and use it to set between Hi Pro and trailer towing. My antilock light came on a while ago and I am getting a P 0603 error code, Are the two related? I think I might have to replace the antilock sensors but dont know where to start. The truck runs fine but the light is very annoying. Can anyone help me out?

P0603 is a Internal Control Module Keep Alive Memory (KAM) Error

Unhook both batterys so the computer will reset. Then see if it sets a code again. The tuner may be the problem.
Check your brake fliud level.

You will get the Keep Alive Memory code when you disconnect the batteries. The code just tells you that the power was interrupted.
