How does ABS work on a Ford Focus?
How does ABS work on a Ford Focus?
Your Focus’s ABS system uses a system of sensors to determine wheel speed when braking. If one of the wheels is starting to lock up, it’ll apply the maximum amount of brake to that wheel in order to keep it from sliding. Wheels that are turning will slow a vehicle faster than a locked wheel.
What causes an ABS light to come on after a hub replacement?
In many cases, replacing one hub bearing will cause the driver to feel ABS false activation when coming to a slow stop on dry pavement. Vehicle had wheel bearing hub replaced on one side.
What causes an ABS sensor to turn on?
A wheel bearing isn’t often considered an ABS component, but it directly involves it and if failed, will throw the system into error mode. If a wheel bearing is significantly worn to the point where the wheel can wobble about its axis, more than likely an ABS speed sensor code will be stored.
Can a new wheel bearing cause false activation?
The new bearing will have little to no play, and the remaining hub will have acceptable play, but can still affect signal strength. Again, the difference in signal from side to side may be enough to trigger false activation. If WSS are integral and not serviceable, replacing the hub bearings in pairs may be the only answer.

What to do when your abs light comes on after a wheel bearing is replaced?
If you have an ABS light on after wheel bearing replaced, you may have to also replace the other wheel bearing hub. Car makers sometimes install the toothed tone ring inside the wheel bearing hub and mount the wheel speed sensor on the outside of the hub.
When does the ABS brake light come on?
If any of the teeth are damaged or missing, the ABS brake light will come on, warning the driver of a problem. The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up.
The new bearing will have little to no play, and the remaining hub will have acceptable play, but can still affect signal strength. Again, the difference in signal from side to side may be enough to trigger false activation. If WSS are integral and not serviceable, replacing the hub bearings in pairs may be the only answer.
Why is the traction control light on in my focus?
Since the only codes you appear to have relate to the rear ABS sensors, I’d suspect either the parking brake lever is pulled up, there is a problem with the brake fluid level sensor or the brake fluid level actually is low. The traction control light is on as a result of the ABS fault codes.
What does the second warning light on the Ford Focus mean?
Whilst the system is malfunctioning, it is deactivated. The second light it also traction control that’s displayed on older versions of the Focus. If traction control is manually switched off, the dashboard warning light will illuminate. The light will extinguish once the traction control system has been reactivated.

What does the ESP / Bas warning light on Ford Focus mean?
ESP/BAS warning light. The ESP/BAS Ford Focus warning light is related to ABS. If this light illuminates, it suggests a problem with the Electronic Stability Program. The ESP/BAS light will often illuminate alongside the ABS warning symbol.
