I have a 2000 GMC Yukon XL 1500. The antilock braked engage when slow to about 5 to 8 mph.


Here is a copy of a GM bulletin that applies to you concerns of low speed ABS activation.

Antilock Brake (ABS) Activation At Low Speeds (Clean Wheel Speed Sensor Mounting Surface) #03-05-25-007 - (09/29/2003)
Antilock Brake (ABS) Activation At Low Speeds (Clean Wheel Speed Sensor Mounting Surface)

1999-2004 GMC Yukon XL

Condition:
Some customers may comment on ABS activation at low speeds, usually below 8 km/h (5 mph). Upon investigation, the technician will find no DTCs set.

Cause
The cause of this condition may be an increased air gap between the wheel speed sensor and the hub reluctor ring due to rust and debris built up on the sensor mounting surface.

Correction
Measure AC voltage and clean the wheel speed sensor mounting surfaces.

Raise and support the vehicle.
Disconnect both the front wheel speed sensor (WSS) connectors at the frame and harness.
Place a Digital Volt Meter (DVM) across the terminals of each WSS connector.
Rotate the wheel clockwise approximately one revolution per second. The minimum reading should be at least 350 ACmV's. If the reading is less than 350 ACmV's, remove the wheel speed sensor. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual. Plug the WSS bore in order to prevent debris from falling into the hub during service.
Clean the WSS mounting surface on the hub to remove any rust or corrosion using a wire brush, or equivalent.

Important
Make sure that the sensor sits flat on the hub. Check the sensor flange against a straight edge to ensure flatness. If the sensor flange is distorted, replace the sensor.

Apply a thin layer of bearing grease to the hub surface and sensor O-ring prior to sensor installation. Use ONLY Wheel Bearing Lubricant, P/N 01051344.
Install either the original sensor or a new one in the hub. Ensure that the sensor is seated flush against the hub. Refer to the applicable Wheel Speed Sensor Replacement procedure in the ABS sub-section of the Service Manual.
Place the DVM across the sensor terminals and recheck the voltage while rotating the wheel. The voltage should now read at least 350 ACmV's.

Good luck and thank you for using Fixya.

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!

ABS and Handbrake lamps on


This is usually caused by one of the front wheel speed sensors dropping signal under 10MPH. the first thing to try is to remove both front wheel speed sensors (Behind brake rotors) and clean the area where te sensor goes into the hole. Then lightly grease the sensor O ring and reinstall it.

Abs lights keep coming on? 2006 Monte Carlo. 44,000 miles. Started car this morning, antilock brake yellow light and ABS yellow light both came on. No change in braking performance I can feel. Is it under...


yes it would be under warenty go to the dealer and have them look at it if you need help after that contact me for more help. It could get expensive to fix yourself and it takes special tools to work on abs, it could be as simple as a bad wheel sensor and has to be fixed and the light reset, the dealer has a computer to test and fix it and it would be no cost to you, the only thing they would not cover is if the brakes needed replaced but the ABS would be covered, and hurry time is short for Gm.

THE SPEED SENSOR IS LOCATED INSIDE THE HUB ASSEMBLY. THE TWISTED WIRES GOING TO THE SENSORS ARE PROBABLY AT FAULT. THE WHEEL SPEED SENSOR HARNESSES ARE AVAILABLE THROUGH A DEALERSHIP.
