    I unplug both sides of the abs module and they both look pretty clean not even a bit of green or missing pins everything looks fine. I swapped the sensors and now i will wait to see what blinking code will give the abs

    I’m back just to give update. Ever since i swap the sensors at the module and and zip tied them to the hoses of the chamber instead on the axle abs did not come on. Idk if this somehow fixed the issue but abs light is gone

    One of the cables from the module to the sensor might have had a bad spot in it. I try to use the plastic hose/cable clamps rather than zip tied.

    If you have original brake chambers have stickers on with haldex logo.
    When you turn off ignition and turned back on light stays on. Start rolling light going out.
    It's a indication for speed signal is missing or corrupted. Have to know what is the exact code. According the age for the trailer possibly abs ring rotted away or split by the rust. Or abs sensor walk out from the metal sleeve.
    But if your light is going out after start moving it is the self test for the system checking your speeds on axles all match light go out problem is corrected.
    If is the speed signal problem light most the time coming back when trailer gets up to 55mph.
