Abs brake system light comes on at times. Brake shoes and fluid levels are good. Light goes off when car is turned off and usually does not come on when started back. It might come back on just driving down the road and not using brakes usually.
ABS system constantly active when brakes applied. Sensors were corroded from winter salt etc. I just pulled the fuse out and killed the system. They are a joke anyways and not required for inspections. A real bad design flaw that costs a fortune to get fixed. Not worth the money. Same yourself a lot of trouble and just pull the 15A fuse in the fuse box. I have driven for over 40 years without ABS just fine and don't miss them one bit. Just more Detroit planned obsolescence to get into your wallet.
ABS system failed, Service brake system light keeps coming on.
brake at low speeds on dry ground, anti lock activates
ABS engages at slow speed braking
abs sensor going on and off then remained on.
When my truck comes to a stop I feel the right front bake let go and the brake pedal pulsates and I am not losing traction.also sometimes while driving at a slow speed I can hear the buzz sound the abs brake system makes when activated...
Anti- lock brakes activate at low speed, causing a no braking situation.
ABS activates at slow speed stops.
It's in the shop today...
One day my Traction light came on and prevented me form driving and code U0121 came which indicated loss of commonication with ABS system.
Current mileage is 67,888. ABS activates when slowing down to come to a stop. I took it in to have it diagnosed. Dealership tried to get vehicle to engage problem but of course it didn't. Dealership cleaned sensors. In all fairness to dealership, the roads were wet and snow covered. Vehicle did activate properly for these conditions. Well, one day later, main roads are dry and wouldn't you know it, as I slowed down at a traffic light the abs kicks in again. Note: the ABS light does not illuminate nor does the traction control light, when this happens. I'm afraid that one day my brakes will fail due to this issue.
abs and ebrake light comes on every couple of days.
Hasn't been fixed yet, not sure what is going on, but cannot reverse or forward without ABS locking up
When I start driving I hear like a rumbling noise off about four tones and the ABS light comes on ABS light goes off after I turn off the car and come back on every time when I start driving making the same noise, noise only appears when you first start driving it sounds like the noise come from the back of the car
ABS runs evn when car is off
brakes pushing back on your foot .suv take a few second to stop.
had hub replaced three times. the replacement only last for about one year.
I purchased my yukon used with 164,000 miles the previous owner informed me of the ABS light coming on occasionally. At 170,000 miles I put a rebuilt module and ABS light stayed off till one year later and 177,000 miles.
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.
Measure AC voltage and clean the wheel speed sensor mounting surfaces.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in the General Information sub-section of the Service Manual (SI Document ID #899664).
Disconnect both the front wheel speed sensor connectors at the frame and harness.
Place a Digital Volt Meter (DVM) across the terminals of each wheel speed sensor 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 wheel speed sensor bore in order to prevent debris from falling into the hub during service.
Clean the wheel speed sensor mounting surface using a wire brush, sand paper, emery cloth, scotch brite, or other suitable material. Be sure to thoroughly clean the wheel speed sensor surface. There should be no rust or corrosion.
Check the sensor head to determine if it has been warped/distorted due to the corrosion build up or other causes. Check the mounting surface on the sensor head for flatness by placing it on the edge of a metal machinists scale or other suitable straight edge to measure the flatness. Check the sensor for flatness in multiple (minimum 3) positions/directions. If the sensor head 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 (Canadian P/N 993037).
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. Service abs system message appears after a few miles of driving along with abs mil. Replaced both wheel speed sensors. Solved problem. Easy fix too. Removed front calipers and rotors, removed the hex bolt that holds on the sensor to the hub and the ten mm bolt that mounts the wire away from the wheel on upper control arm. Re installed in reverse procedure and never had an issue since.
