NOTES TO THE FAULT CODES EBS - 2

If you have to EBS electrical faults, system response may be manifested in the symptoms of "open circuit in the pressure control EBS" or "deactivation pressure EBS control."

 

Open circuit in the management of EBS pressure

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

The electronic block of the command vehicle deceleration is converted into the braking pressure in the brake cylinders.

If there is no feedback from the output pressure or wheel speed, precision electronic controls deceleration of the vehicle and the brake force distribution is reduced.

 

Deactivating the EBS pressure control

Pressure control output in pneumatic brake cylinders completely, ie electronically controlled deceleration and brake force distribution is not working.
