The Anti-Lock Braking Systems (ABS) have been a standard feature on cars for years, preventing the brake pads from pressing against the brake drums and causing the car to skid. ABS also enables the car to stop on a shorter distance and allows manoeuvring while braking. The system works based on a number of wheel speed sensors; it checks the brake fluid pressure and reacts accordingly when the brake pedal is pressed.

How does the ABS controller work?

A properly functioning ABS system collects a lot of information so that it can react quickly to the driver’s actions; it is based on collecting information about which wheel is rotating, it can adjust the braking force for the individual wheels of your car. It also works in conjunction with the ESP (Electronic Stability Programme) to ensure the safety of the driver and passengers. An important task of the ABS system is to maintain an even rotational speed of each wheel in the vehicle. If you notice any irregularities related to braking, you should have your car inspected.

Signs of ABS controller failure

Failure of the ABS controller can sometimes be difficult to locate; problems may only occur when the engine is hot or cold. The dashboard light may come on after reaching a certain speed so ABS controller diagnostic inspection should be carried out by an experienced person who has the right equipment and software. Therefore, diagnosis and repair can be quite expense, and it can often be difficult to find a suitable workshop that deals with ABS pump repairs.

Buying a new pump can be quite expensive, and in the case of some car models older generation controllers may no longer be produced. So you are left with the purchase of a remanufactured controller; many models are available on Wanted: an ABS pump controller. These controllers come from original vehicles so you can be sure that they will fit your car model. The controllers have been inspected; all damaged parts have been repaired, so you receive a fully functional ABS controller.
