2003 Yukon: Fuse to cut off ABS?

[05alive]

Yup. Pull the ABS fuse and it wont go into antilock until its replaced. The wheel speed sensors cant get "stuck". They are built into the wheel hub assembly and unserviceable. What can happen is the abs pump stays on and burns itself up. It is not rated for 100% duty cycle.

Speak out of the other end bud.


Wheel sensors are entirely serviceable. Replaced both of them two weeks ago. And pulling the fuse kills ABS completely. I ran with the fuse pulled for close to a year with no issues. Pump wasn't running. ABS pump works today.

The hubs are sealed units. Have a link or reference that shows a seperate part # for the sensors up front or a video link of them being changed?

Really, that is the way you are going to approach this? Like a child. I never said anything about the abs pump running once the fuse is pulled. Learn how to comprehend while reading.

I stand corrected on the ABS Sensors, but what years does that cover?

I had someone check sensors on computer and they all working and registering the same speed but when I slow down still hard to stop. what else could be wrong? 1999 GMC Yukon Parking light does not come on

Take the fuse out for now so you don't rear end someone or drive into the intersection. The fuse is in the fuse box under the hood. Im sure you can read the diagram and pick the correct fuse. When you pull it and turn truck on .., the ABS light will come one. and the Parking Brake light as well. (I believe thats what will happen as thats what my 2002 does)

Sensors are removable 100% on my 2002.

However when you buy a new hub/bearing assembly they come with new sensors.

You should verify which sensor is bad. For about $45 you can buy a new sensor. Not hard to change. Unless you have access to scan tool to watch abs sensor voltage while driving you could just change both and have two brand new sensors taking care of the issue for some time!

If your front bearings inside the "hub assembly" are making noise or you don't know when they were replaced you could change the hub assembly and as I said above it would come complete with a new sensor. That will cost you more money. Hub assembly cost roughly $200-$300 a piece?
