Abs light is always on, until the vehicle warms up, then once about 63kmh is reached it will shut off. When braking or slowing down without brake from over 63kmh, light comes on again at 63kmh, and stays on. I have no abs brakes working. Truck was bought one month ago. I replaced rear backing plates, emergency shoes, and 2 brake lines on axle. Bled system, thoroughly. Thanks for any helpful fix solutions. Lidster

 

did you try checkin the ABS sensors themselves or the wiring

 

I checked sensor, noticed the teeth were chipped on the rf hub. I Have to get this vehicle safetied. Didn't find pieces of teeth in hub assembly. I ended up, jumping wires from right sensor to left sensor on the fender at the abs module. Due to time and finances. Light is out, and abs still works. Lol. Good for now, until bearings blow apart. Time will tell???
