I have the P01C6 and C0020 code on my truck and when I turn my truck off the ABS pump keep running.
All started when I was pulling a load of bales up a hill at my place. Driving at 20-30kph didn’t shift out of first and ran loud. Then at the top of the hill I shut the truck off and the pump kept running.
Now I have those codes, and on my dash I have abs light, parking break light, and a note that advance trac needs servicing.
do I need to replace the abs control module, or is there a abs pump relay I can swap out?
I wish people would post what the codes say when they ask a question. It would save a lot of looking up and get you a answer faster. So the P01C6 has nothing to do with the ABS. Code C0020 is a abs code but it could be a number of things. There is a sub code C0020:12 or 13 or more that describes pump motor wiring either shorted to battery or open circuit. Does it ever shut off?

Thats a fair point Fefanatic: should have posted the C0020 code. As you mentioned it is the abs/hcu fault. I read the code off my EZlink DTC On my phone, and it didn’t give me the sub code. Looking it up now there seems to be 7 sub codes for C0020.
But to answer your question, no the pump keeps running and It does not turn off: I had to pull the pump fuse to stop it.
so with the fuse out, and all the warnings on my dash including the “service advance trac”, and “parking break on”, and “hill decent fault” I’m wondering if this is an Abs module issue?
