    ABS starts to operate just before I come to a complete stop, even on dry pavement. New pads and rotors, had abs system checked out with computor, no problem indicated.

Does the abs light come on ? there was one cause on the van that i owned (ford windstar) that can happen to any vehicle. the ring that the sensor reads from can become crack. that causes the teeth to not be aligned properly. just curious... have you had your brakes replaced recently ?

Traction active message coming on in a 2003 hummer h2

Hello! This is usually the result of a wheel speed sensor issue. Most technicians look for WSS fault codes, to decide which one is failed, but if there are no fault codes, they don't know where to look. The trick, is with the scantool hooked up, watch the ABS solenoids and see which ones activate during the traction event. If the Wheel Speed Sensor is acting up, it can confuse the ABS module into thinking that wheel is slipping and it will activate the ABS pump and solenoids for that wheel, to try and slow it down.
With the stability system disabled, it won't try and slow the "slipping" wheel down, which is why it won't do it when disabled.
and the noise you hear is probably the ABS motor and solenoids, which are mounted on the Left Frame Rail, below the drivers seat (often heard at the firewall).
There was a bulletin to replace the Yaw Rate Sensor and update the ABS Software, which is probably where the $400 went, and it may have needed it, but obviously that wasn't the problem. I beleive that the issue lies withing the Wheel speed sensors.
the most common symptom of speed sensor failures is premature ABS activation, but I have in some instances see it cause Traction Control events take place as well. Here is a service bulletin for unwanted ABS activation:

My Yukon ABS brakes keep me from stopping on uneven roads and in turns

if this issue is at low speed roughly five to ten mph it is a sign of a bad wheel bearing as the abs speed sensor reads off of a tone ring attached to the front bearings, when the bearing gets too much play it causes the sensor to receive an eratic signal making the on board computer activate the abs thinking the vehicle is sliding

I have a 2002 gmc yukon. When i press my brakes my antilock brakes go off and stopping is tough. what could this be?

you need to connect a diagnosing scan tool and go for a drive. during an ABS event, watch the values of the wheel speed sensors on the scan tool. chances are one will not be accurate, causing the abs to activate. the sensors are integral to the wheel bearings, and are changed as a complete unit. this is a common failure. good luck!

there are any number of components that cause this light to come on, the only thing you can do is have the GM dealer test the ABS module for the trouble code that is stored whenever this light is set to on. The most common problem is dirty wheel speed sensors, but there are 4 of them and once again you have to guess without the test.
