C0020 on Ram vehicles
293 owner complaints filed with NHTSA about Ram vehicles mention C0020 (ABS Pump Motor Control) - across 3 models. Below is where it shows up, by model and year.
Can you drive with it? With ABS simply offline (light on, brakes feel normal): yes, carefully - base brakes work, you have just lost the anti-lock safety net. But if ABS activates on its own at low speed or the pedal buzzes on gentle stops, stopping distance is affected - that version is a repair-now problem, not a someday one.
Symptoms, likely causes in order and realistic repair costs are on the main C0020 page - they do not differ much by brand. This page shows what is specific to Ram: which models and years actually report it.

“I am in Virginia and received a recall code C0020-01 for general abs fault. The truck continues to beep alerting me of this fact. I need replacement of the hcu. Which i have been told controls the breaking hydraulics. To me this seems to be of concern and could easily cause an accident and injury. This has been occurring since August of 2025 and I have been in contact with the dealership, Blackwell of Danville, VA, since then. On 11/1/25 I went into the dealership for other issues but this problem as well. They told me there is no part available for replacement and hasn't been for over a year. Well we are in a new year so how much longer do I need to wait for my truck to be safe?”2018 Ram 2500 · Aug 2025
