    which breaks come on rear? are they drum? if the sensors had an issue with the signal they would turn the ABS light on and it disable the whole system.

If its the front sensors,you have to remove the backing plate to get to the sensors.Alot of time you have rust building up between the hub and the sensor,which pushes the sensor away from bearing and thinks its on a slippery surface.You need to clean that rust out from between sensor and hub.There are three bolts holding hub and backing plate in place,you have to remove these things to get to sensor.Hope this helps.

That light is a "Dummy" Light. It is telling you that you need to Either Bleed the System and/Or Replace your Brake Pads.

ABS computer is receiving erroneous signals into the ABS computer. Wiring loom connections need checking. Disconnect, reconnect wiring looms around engine compartment dealing with abs equipment. Spray contact with contact cleaner.

I have toyota corolla AE 110 with 5A engine 1998 model, three days ago my mechanic changed the right CV Joint (drive shaft),from there the ABS indicator started to come on,then it went off after sometime ...


Hello and welcome to FixYa!

As a first course of action, clean the abs sensor by using a contact cleaner. If the problem still persists then the sensor can be faulty, it may have been damaged too during the CV joint replacement. If that's the case, you will have to replace it if cleaning won't do the trick.
Hope this helps and thank you for using FixYa! Have a good one!

GM has had an issue with rust building up on the on the abs sensor mounting surface located on the bearing. This rust build up causes an increase in the air gap between the sensor and the exciter ring. What can be done is to remove those abs sensors on the front wheels and clean the surfaces of the abs sensors be sure to cover the holes that the sensors go in to avoid particulates from getting inside the hub bearing once the area is cleaned you can apply a small amount of grease on the mounting surface then reinstall the sensors. Several vehicles with this issue have been corrected in this manner.

This is a common problem with these trucks. You will need to set-up an appointment with the service Dept. at the dealership. There is an update for the ABS system. The function of this update is to reduce the sensitivity. When you get down to five MPH (with the brake applied) the ABS turns on (no light on dash) and you get the sensation of Sliding (braking is reduced).
This is assuming that the tires are the same size and pressure, And that there are no defects in the wheel speed sensors. Good-luck and please let me know what you decided to do and how it went.

ABS problem with GMC 2002 Sierra


its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

Where is the abs sensor on a 1998 chevy venture


there are four ABS sensors. one behind each wheel in the hub assmebly just follow the shielded wiring harness down to the sensor, it is at the behind the brake rotor in the hub assmebly, the lock up problem is not the sensor, the function of ABS is to stop lock up of the wheel, this problem is caused by a leaking ABS hydraulic control unit, that is the part with all the brake lines coming out of it

Or you could just pull the fuse for the abs and not have abs but you won't wreck from pulsating pedal.
