    Service ABS System

    I have only had my truck for a couple of weeks and was going down the road today and on the dash popped up service abs.

    My abs light came on, and my traction control light came on.

    It went on and off several times before i got home. Has anyone else experienced this?

    2018 RAM 2500 Megacab 4x4.

    Mine lights never stayed on.

    They went on and off several times but never stayed on more than 5 seconds.

    Glad I bought the extended warranty.

    My truck only has 45k miles.

    Sounds good, please keep us posted.

    If you do decide to scan for trouble codes, you will need a scanner that is capable of reading the ABS module.

    More than likely, the hydraulic control unit is failing.

    Very common issue.

    If the code ends up being C0020, it’s the HCU.

    Thanks for the help.

    I'll keep that in mind when the light stays on.
