If the above error is discovered together with an illuminated ABS warning light, this may be due to the brake pressure sensor.
The pressure sensor records the brake pressure in the hydraulic system and relays the value to the control unit. A signal evaluation error leads to the entering of an error in the control unit. As it is not possible to take measurements on the sensor itself, first check the voltage supply and peripheral equipment of the ABS system. If all measurements are consistent with the set values, the pressure sensor must be replaced.
The pressure sensor is integrated in the ABS hydraulic unit and cannot be separately replaced.
If damaged, the entire unit must be replaced.
