Electronic Braking System Needs Service Error that can't be addressed at the dealership.
I had an intermittent abs/traction control light that now stays on 90% of the time. Code C0020-01 for ABS general electrical failure.
ABS and traction control lights keep turning on and off. Truck currently has no ABS.
ABS and Traction control has been lost and have created a safety risk especially during inclement weather. The ABS pump or the ABS control Module is faulty in multiple years Ram vehicles. I believe based on forums there is a recall issue with these parts.
I’m receiving two codes; Service Antilock Brake System and Service Electronic Braking System. I met with my mechanic this morning and he said that this is a very common problem with the 2018 Ram 2500. Since this is a reoccurring safety issue i feel that Dodge should resolve not the owner. Should I get in an accident from a break failure who is responsible?
The HCU in which controls your ABS and Traction control will malfunction while driving down the road when this happens you have no ABS, traction control or cruise controls. The dealer part is unavailable through the dealer due them saying that they are reviewing it. This is a major safety concern due to the fact if you are traveling and it malfunctions and need to stop quickly you cannot or if it malfunctions and have cruise control set to a speed it will slow you down and can cause an accident. When vehicle was carried to dealer and asked what to do the dealer just said to drive it and don’t follow to close to anyone, that is not the answer that needs to be given.
ABS light and traction control light comes on – says service electrical break system and antilock brake system
While driving, ABS system warning lights illuminated accompanied by intermittent alarm. ABS System Failure confirmed by selling dealer, further confirmed via Fiat Chrysler Automobile (FCA) TSB notice "C0020-01-ABS PUMP MOTOR CONTROL - GENERAL ELECTRICAL FAILURE." This TSB particularly confirms/advises both the HCU and the ABS be serviced / replaced. The original pump motor is no longer available and per dealer is being re-engineered due to defect. This failure is a significant risk to the vehicle operator, passengers, and the general public and should be remedied immediately at the manufacturer's expense via NHTSA / FCA initiated recall.
Service electronic braking system / ABS service antilock brake system. Both these lights come on and ding, half a second later they are off. This happens non stop, looks like everyone is having this problem. This should be a recall not a $1200 fix. I only have 58,252 miles on my truck. This problem for me has been going on and off for 2 months.
At around 74,000 miles in December of 2023, a warning to "Service Electronic Braking System" and "Service Antilock Brake System" started to show up on the screen of my 2018 Ram 2500 6.7. The truck was taken to a Ram dealership and the fix to the problem was determined to be replacement of the ABS module in addition to replacement of the HCU. Apparently, the ABS module is faulty and is causing the HCU to go bad so both need to be replaced. Replacing only the HCU will not fix the problem. The truck has not yet been repaired as a new ABS module is not available until June of 2024. When driving, the on screen errors come up frequently at all driving speeds and the error is present the majority of the time while driving.
ABS system and traction control lights turn off and on intermittently. ABS pump and module have already been replaced and issue is still happening
ABS/HCU is a known issue for failure. Mine is intermittently flash alerts for service/problems. 1000’s of people are having these issues. Where is the recall? This is a safety issue, is it not.
As with thousands of other owners with this model of truck my anti-lock control module is bad. The malfunction causes the anti-lock brakes service light as well as the traction control service light to be on. This malfunction renders both systems to be inoperable, thus causing a major safety concern.
Abs control module had went out twice in 3 years and hydrolic unit causing brakes to fail
Purchased truck and abs light is on that disables abs and traction control. Which in turn won’t let you use cruise control
ABS light and Traction Control service alert light on dashboard. Second time this has happened. I had this issue prior and had Ram replace both parts that needed to fixed and was not covered by Ram. This/ these are faulty parts and Ram needs a recall. There are thousands of Ram owners that have the same issue and Ram refuses to acknowledge and recall these parts/ issues! Please help us!
"Service Antilock Brake System" & "Service Electronic Braking System" error messages are popping up on the dash on and off while truck is running. Sometimes pop on after starting the vehicle while sitting in drive and other times while driving.
While driving the truck my ABS, Traction Control and red brake symbol come on the dash as a warning. The vehicle once this happens no longer can utilize cruise control nor its ABS system during hard braking. This problem began intermittently and has become permanent. Dealerships are unable to get parts for repair.
Abs problems due to HCU

2018 Ram Sept 23, 2020 at 15,000 miles ABS light flashed on. Code said pump electrical failure. Dealer replace under warranty. Oct 12, 2023 at 50,900 miles, service ABS notice flashes on screen. Dealer confirmed ABS failure but said parts were on indefinite back order. Said last one took over a year to get parts in.
Intermittent warnings of ABS system needing maintenance while driving. No known cause or correlation to type of road/weather conditions. Intermittent ABS failure affects ability to use cruise control. This started when the truck was at 52k miles. This has been happening for over a year now and we have been told that there is an indefinite timeframe for repair due to massive back orders.
