Consumer Description
My 2018 Ram 2500 has 85,000 miles currently. At about 80,000 miles I got the ABS and Traction control warning lights along with dash messages to check the ABS amd electronic braking systems. I am a heavy equipment mechanic and thus checked the systems myself with a scan tool and other test equipment. I found that the ABS module has an internal electrical failure resulting in power not being supplied to the ABS pump/electric motor. I have verified that the pump works and has about a 48ohm resistance. If supplied with 12v and ground to the motor it will come on. Circuit testing from the electrical plug to the contacts for the motor one pin has contact and the other is an open circuit. I also have one seized plunger in the hydraulic control unit that is actuator by the motors eccentric lobe on the output shaft. After doing some research online I've found this is a very common issue on the 2017 and 2018 Ram heavy duty trucks, the 2500 and 3500 model specifically. I also found that neither the hydraulic control unit nor the ABS module have been available for purchase for a long time. I myself have been trying to order one for about 6 months. No dealer in my area can even give me an estimate time of availability. So currently I and many other have to drive a vehicle with a failed ABS system. This poses a greater risk of collision and unsafe braking. It is also a requirement to be working to pass a vehicle inspection so selling the vehicle or depending on state lived in you may not even be able to drive the vehicle at all.
