ABS test and repair
AP-Reman have developed our own in house test rigs for ABS testing and repair, these systems allow us to replicate real world driving conditions.
All defects are repaired to the highest standard and where possible components of a higher quality are used resulting in a repair that is of equal or better quality than the original manufactured unit.

What is a ABS system ?
An anti-lock braking system (ABS) is a safety anti-skid braking system used on vehicles such as cars, motorcycles, trucks, and buses.
ABS operates by preventing the wheels from locking up during braking thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle
.
An ABS pump combined consists of multiple components such as : ABS module / ABS hydraulic unit / ABS pump motor.

ABS module
The ABS module is the electronic control unit (ECU) that is responsible for reading and calculating the data it collects from multiple sensors such as wheel speed sensors, yaw rate, brake fluid pressure, individual wheel brake pressure, longitudinal and lateral acceleration, steering wheel angle, engine and gearbox speeds.
The ABS module calculates the data then applies the exact amount of braking force required during emergency braking conditions and can also control each wheel individually by operating the hydraulic solenoids within the ABS hydraulic unit.
ABS modules (ECUs) are common for failing which can cause multiple problems such as communication errors, individual or multiple wheel speed sensor faults, solenoid valve faults, steering angle sensor faults, internal control module faults, brake pressure sensor faults, pump motor faults, vehicle programming or coding faults and non start of vehicle.


ABS hydraulic unit
The ABS hydraulic unit mechanically regulates brake fluid pressure individually to each wheel, the regualtion is calculated by the ABS module which then fully or partially activates or deactivates the solenoids within the ABS hydraulic unit.
The ABS hydraulic unit may have 1 or more brake pressure sensors which send data to the ABS module to monitor the braking pressure applied by the driver and or the brake pressure at each wheel
. Brake pressure sensor faults and solenoid valve faults are common failures.

ABS pump motor
The ABS pump motor is controlled by the ABS module, the operation of the ABS pump motor regulates the amount of pressure within the ABS hydraulic unit during emergency braking conditions. ABS pump motor and ABS pump motor connector faults are common failures.
