Citroen DS4 - Repair abs pump

What is an ABS block?

What is the ABS block used for?

For the record, the ABS system has been around since 1920 in the airline industry: it was necessary to prevent airplanes from skidding on landing. The ABS block regulates the pressure of the hydraulic fluid that transits from the pedal to the brake calipers. Thanks to a sensor, installed on the wheels, the ABS block can thus release the pressure on the locked wheels, to give back the control of the vehicle to the driver.

The ABS system to avoid wheel lockup

The ABS block is part of the global ABS system. We discover for the car manufacturer Citroen DS4 ...

• The wheel speed sensors: each of the sensors is placed in front of a rotating notched wheel, which generates a magnetic field variation and induces a sinusoidal signal.
• The magnetic targets: they generate signals read by the sensors, which transmit these signals to the ABS computer.
• The ABS block: what are the elements that make it up? This is what we will discover ...

The ABS block

Let's take a look at some of the elements of the ABS block of the Citroen DS4 model:

The motor driving a hydraulic pump

It uses the flow of oil that is pushed into the hydraulic circuit by a hydraulic pump and transforms it by a rotary motion to drive another device such as the differential or the wheel, etc.

The ECU

This is the part that receives the signal directly from the brake pedal.

The hydraulic unit

It is made up of several components including:

• Pressure accumulators which are pressurized gas reservoirs used to provide a large flow rate for a fairly short time.
• Solenoid valves that regulate the braking pressure for each wheel.
• The electronic splitter that modulates the pressure on the rear wheels.
