Default 2-wheel or 4-wheel-ABS

Hi Folks!

can you say me, if my truck has a 2- or 4-wheel-ABS?
its a RAM2500, 4x4, HD from '03/'04

When i brakes on snow and ice, i see in the mirrow, that the rear-Wheels blocked and only the front wheels are braking with ABS...

If you have two-wheel, it'll be on the rear wheels only. Four-wheel will include the front wheels. Two-wheel will allow the fronts to lock first.

I do believe you have 4wabs. The abs controller has the 2 connector plugs and 4 lines going out. At least that's the same controller on my RT and I have 4wabs.

I've learned that pleasing everyone is impossible, but pissing everyone off is a piece of cake.

Taking a picture of the ABS module wont tell me anything but if you need to know for sure, get under the truck and look at the spindles and there would be a wire coming out of the wheel bearing hub. That wire is the ABS sensor in the hub assembly.
