A properly functioning ABS system will minimize any sort of traction loss, especially under wet and icy conditions.
Why does ABS automatically activate?
During heavy braking conditions the ABS system should automatically activate to aid in slowing down the vehicle, and traction loss and skidding should be minimal. While we should try to practice regular driving habits that avoid heavy braking situations, if you do notice that the vehicle is taking longer to stop under heavy braking situations, or is experiencing traction loss and skidding, then that may be an indicator of there being a problem with the system. The ABS system is typically made up of only a few components - the module and the sensors - so a problem in its operation will either be with the module or the sensors.
How does an ABS system work?
The anti-lock brake (ABS) system uses sensors that send data to the ABS module which will activate it during wheel lock. These sensor mechanisms are installed at the wheel, and is usually made up of two components. There will be a reluctor wheel or tone ring seated on the axle which will spin with the wheel, and either a magnetic or hall effect sensor which works together to send data to the ABS control module. Over time, the reluctor wheel may become dirty or damaged to the point where it can no longer provide a consistent reading, or the magnetic/hall effect sensor may fail. When either of these components fail, the ABS system will not function properly and will require service.
