A leakage of brake fluid in the brake system: 1) Brake lines of wheel circuits FL, FR, RL, RR, 2) Output valves of wheel circuits FL, FR, RL, RR, 3) Low pressure seal of main brake cylinder 1 piston, 4) PSV valves of plunger. 5) Significant air in the brake system. An air in the brake system: - wheel circuits (incl. callippers) FL, FR, RL, RR, - main brake cylinder primary circuit (1), - main brake cylinder secondary circuit (2), - internal circuit below CSV, LEM evaluates pressure behaviour based on the active test sequence. The test sequence is executed in Postrun phase after a usual driving situation. Hereby the plunger provides a hydraulic pressure and stops. If pressure is dropping, then a leakage can be calculated. AIM evaluates pressure behaviour based on the active test sequence. If a combination of leakage and air is too high then the fault is set.

Hyrdraulic pressure may drop during a leakage test. System will be running with internal degraded pedal map. Braking may require increased effort.

Wrong ECU Exchange. Mismatch Linear Position Sensor IDs in NvM with Linear Position Sensor IDs from sensor.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

Plunger is not possible to build up necessary pressure in brake system. Caused by: Significant loss of brake fluid - external (broken brake pipe) or internal (seal or valve defect). Large Leakage alert is assumed if the pressure sensor shows significant lower values than expected at maximum possible plunger position.

The pressure sensor value is too low, the Pedal Travel Sensor value is too high, there is air in the hydaulic circuit, or there is a leak in the hydraulic circuit. A Brake Signal Monitoring (BSM) soft pedal characteristic alert occurs if the current pressure sensor value is too low for the current pedal travel sensor value.

System will be running with internal degraded pedal map. Braking may require increased effort.

The input rod sensor signal shows a positive value that is larger than the specified offset of the sensor during driving situations. This might be due to a sensor condition, mechanical issue in the pedal assembly, or the driver pressing the pedal. The monitoring counts the time in which the input rod sensor signal is higher than a threshold and the acceleration pedal is applied simultaneously while the vehicle is driving. The input rod threshold is higher than the specified sensor offset for reasons of robustness.
