If you have rear abs then yes. you may have pinched the cabl attached to the wheel bearing

My abs and brake light stay on while am driving


The computer has detected a condition that indicates a fault with the ABS/Traction system. Typically that's caused by a wheel sensor problem, but it can also be caused by a faulty connector, peripheral device or the computer.
The above is the shop or garage answear. How about telling us how to fix the problem , besides replacing the computer or wheel sensor? How do we check these things?
Sometimes can be as simple as a short circuit in the rear break lights or a faulty connection in the break lights.
You can start checking the break light system. Then the sensors and finally the computer.

2007 hondaodyssey front left speed sensor


A front wheel sensor in this case is the ABS sensor. Chances are the sensor was damaged when the wheel bearing was replaced.

The sensor is mounted on the wheel bearing carrier/housing in such a way that it is ½-1mm or so away from a tone ring, a segmented or toothed ring often on the outer CV joint (technically a Rzeppa joint) outer surface. The toothed ring rotates and the Hall-effect magnetic sensor picks up and transmits the square-wave signal to the antilock brake system electronic control module which uses the signal to activate the brake or control the engine power output in braking or stability control situations. If it has failed you should have a bright yellow circle on your instrument panel with ABS inside it.

ABS LIGHT ON DASH?


Antilock Brake System, If its by it's self it means there is a fault. If accompanied by the regular red brake light normally means the problem is with the regular hydraulic part of the braking system. It also means your Antilock system has been defeated.

ABS light keeps coming on


You have a wheel speed sensor that is not working correctly. The ABS computer is losing the signal from the wheel speed sensor and interprets this as a wheel locking up, so it is going into antilock mode. When it does this on dry pavement when it is obvious that there is no wheel actually locking up it is called "false Antilock Mode" or "Overactive Antilock Mode". This is a pretty common problem on several vehicles.

The system on your Blazer uses wheel speed sensors which are an integral part of the front wheel bearing and hub assembly to determine wheel speed for the front wheels. It uses the Vehicle Speed Sensor (VSS) to determine rear wheel lock-up. The VSS data is shared between the Body Control Module (BCM), the Vehicle Control Module (VCM), The Powertrain Control Module (PCM), the Transfer Case Control Module (TCCM) and the Electronic Brake Control Module (EBCM - AKA "Antilock Module").
The problem is MOST LIKELY being caused by a front wheel bearing being loose (pretty common) which will require replacement of the front wheel bearing and hub assembly. However, it can also be caused by the VSS or a breakdown in communication between any of the modules that share the VSS data.

If you have either of the front wheel bearings making noise (growling or whining) then that is almost positively the cause of your problem. However, if it cannot be determined this way, the computer network will need to be scanned to find out which it is.

ABS stays on a 2001 GMC Jimmy


This is a common issue, and is pretty easy to fix. There are ABS sensors on the wheels, and you have a bad one. Usually the wires become corroded, and are easy to spot. The unit is on the back side of the wheel assembly.

ABS light & trak off light keep coming on. Grinding noise & vibration can be felt on brake peddle. Brakes have been checked. Wheel bearing was replaced on drivers side. Sometimes making a pulsing...


It sounds like "False Antilock Mode" to me. Your Antilock Brake Control Module "thinks" that you have a wheel locking up. This is probably caused by a bad wheel sensor. You need to scan the module to find out which one.

Antilock light is on and trac light is on sound


You have a bad hub bearing. 100% garunteed. The light is on because the bearing is so bad it hit the sensor for the abs & traction control , breaking it. So you're gonna need a bearing, a sensor,probably new brake pads,any seals{probably one} & a shop that can do it. The bearing is pressed in & needs to be pressed out. Heating & beating is not a good idea.

Antilock brake /trac off light stays on...140000 miles


In those cars, the wheel speed sensor is integrated into the wheel bearings. When one of the sensors goes bad, you have to replace the entire wheel bearing. Also, when the sensor(s) go bad, it will cause the loss of anti-lock braking and disable the traction control system.

The only way to identify which wheel bearing it is, is to hook the car up to a scan tool capable of reading ABS codes. That said, the front ones are more notorious for going out than the rear ones.
