I have a 2001 Tahoe LT 2WD. At random times during driving, the ABS and e-brake lights come on (together). Lights are not on at first start up. Nothing mechanical is wrong. Brakes are good. Not sure if it is the WSS (wheel speed sensors) or the vehicle speed controller.
Please help

The abs should be scanned with an appropriate scanner to access abs codes and wheel speed sensor inputs.

I have just read your other post wheels squeeking! and you have the abs light on....you need to remove the rotors and find out if the abs sensor wires are damaged and also check for the sensor voltage output of 500mv a/c when spinning the front hub...

If the front abs sensors are removed you can inspect for metal debis in the hub hole if this is found the bearings are n/g..


bearing/abs front sensors very common problem.



I just took care of my sensors yesterday low output 300mv...caused abs to come on at slow speeds..rust caused this on my vehicle...on yours it seems like bearing failure is fouling the sensor face with metal and you get no output which causes the abs light to come on after vehicle movement..
