DAF LF, CF, CP COMMENTS FOR FAULT CODES EBS

If there is a fault in the EBS system can be symptoms of "open circuit in the EBS pressure control" or "Pressure control deactivation EVS".

 

Open circuit in the management of EBS pressure

When triggered, the brake valve electronic control unit receives information about the desired vehicle deceleration from the brake pedal position sensor.

The electronic unit, this signal is converted into pressure applied to the wheel cylinders.

In the absence of a return signal at the output of the pressure or speed of the wheels, the electronic control accuracy of braking and brake force distribution is reduced.

 

Deactivating the EBS pressure control

output pressure control in the wheel cylinder is carried out solely by means of pneumatics, ie electronically controlled deceleration and the distribution of braking force is absent.
