Could you possibly tell me what the fault is? I think it may be the tone ring. but i am open to all advice

Snow or debris on the ABS tone ring or
Stabilitrack light on Ricks Free Auto Repair Advice

your car has a fault in the system that senses wheel speed and changes the way the car automatically responds to slippery road conditions. Often, successful troubleshooting of these faults will require the use of a special scanner; however, there are a couple of failure modes that a backyard mechanic can discover and correct.
If your ABS AND your brake light (on the instrument panel) are both on, it is likely your basic brake operation has a fault. In this case, please refer first to the tip on Brake Light Indicator.
First, let's understand how these systems work. The car/truck must have a sensor at each wheel to know for sure if any wheels are slipping. The usual method is to use a tone ring and sensor as shown below.
The signal from each of the 4 sensors is evaluated by the ABS system, which, if the brakes are applied, will essentially pump the brakes for you to prevent skidding. If the brakes are not applied but you have traction control, the traction control system will limit the differential behavior of the drive wheels to help you get traction. If you don't have traction control, the ABS system may alert you to wheel slippage with a "low trac" light. The logic and electronics associated with the reactive systems is different on different models, and that is why troubleshooting those parts of the system requires special scanners and training.
OK, so what can you do about getting those lights off without paying a specialist big bucks?
You can inspect the wheels for damaged tone rings, broken sensor wires or connectors, and misaligned sensors. The tone ring is usually visible at the end of the CV boot on a drive axle or behind the rotor on a non-drive wheel. For wheels with drum brakes, the tone ring may be inside the drum.
Spin the wheel looking closely at the tone ring for any missing or chipped teeth or a break in the ring. Check the sensor alignment to the tone ring and also the distance. If you can find the specs on the air gap, measure and adjust as necessary. If you can find specs for the sensor, check it with an ohmmeter for shorts and opens. There are a few more details on sensor diagnostics at the following page:http://www.brakeandfrontend.com/diagnosing-wheel-speed-sensors/.Check the connectors and trace the wires all the way to the ABS module to inspect for damage. Due to the variety of systems and conditions, I'm not going to try to cover repair procedures.

Tone rings are a break for the magnetic field produced by the sensor if you have to much air gap you would get a erratic signal if the tone wheel is broken any where this will produce a fault or failure, if the sensor fails same result.a scanner can read this signal if the sensor can produce it other wise you may have a open circuit usual failure is the sensor.

The sensor operates in conjunction with the TONE RING, located on the axel under the sensor. The tone ring is probably physically broken due to rust swelling. The tone ring resembles a gear and the sensor "sees" the notches on the ring. When the ring breaks, the sensor can't read it correctly. Part is 6 bucks from rock auto. Installation is quite involved(remove axel). There are instructions posted somewhere online. Search! Get ready because I think all 4 wheels have this ring and they WILL all break at some point. Oh when the right front ring goes bad, you will think the motor is falling out. Clunk, bang. losses power but new ring will fix.

there should be

Tell him to clean the sensor to put the light out. It is bound to be more than dirt. Once the ABS light is on, you usually have to empty your wallet to put it out. Maybe it's a sensor, but not from dirt. Maybe a wire broke, sometimes a tone ring splits. You can easily do a visual inspection of the sensors, tone rings, and wires; but if those are good, it's probably the control unit. I have pasted a picture of the tone ring on the axle. The rear tone rings are inside the drum and less susceptible to damage. Make sure the tone ring is square on the axle and not loose--no missing teeth, etc. Sensor should be square on the tone ring. Let me know if you have more questions.

Possible faults:

Different tire rotational speed wheel to wheel.

Broken wire loom to wheel sensor.

ABS Tone ring missing teeth, broken.

Bad ABS wheel sensor.

Dirty Tone ring...... brake dust and rotor dust.

There is always a reason for warning lamps to illuminate.

The whole bearing bad, has to be replaced,but it most likely is not the problem,make sure there is no metal bits of the rust stuck to the abs sensor.
