Renault Scenic 4 - Repair abs pump

What is the purpose of the ABS block?

The ABS block and road safety

The ABS has been mandatory in Europe since 2003. It works through sensors, a computer and a hydraulic control system. In the event of emergency braking, the ABS block ensures that the driver retains control of the car. Indeed, locking the wheels in such a situation would cause a slide on the road.

A valuable assistant: the ABS system

The ABS block is a part of the overall ABS system. We can notice for the Renault Scenic 4 car ...

• The magnetic targets: they are represented as a sequence of north and south poles. The alternation of the poles varies the output signal.
• The wheel speed sensors: there are 2 types, the active sensors operating through electronics, which are supplied via a voltage determined by the ABS computer and inductive sensors.
• The ABS block: the information below helps to understand the importance of this element.

The ABS block

In an ABS block of the Renault Scenic 4 automobile, we observe among other things:

The ECU

The hydraulic unit

Many elements make it up including...

• Electronic brakeforce distribution, which is an additional function managed by the ECU.
• A hydraulic pump whose action ejects the fluid stored in the accumulator to the master cylinder, preventing the pedal from depressing.
• Solenoid valves that limit the braking pressure of each wheel.
