A positive value indicates acceleration, i.e. the front of the car is raised. A negative value indicates deceleration, i.e. the front of the car is lowered.

Measurement range: -20 - +20 m/s2

HINT: The value can be affected by changing the longitudinal incline of the car, for example by raising or lower the front or rear end of the car.

VACUUM PRESSURE, WORK CHAMBER 

The value indicates vacuum pressure in the operating chamber.

Measurement range: 0 - 0.95 bar

OFFSET VALUES 

HINT: The offset value is an adaptive correction value which indicates the individual offset for the sensor. The Brake Control Module (BCM) uses the value to determine the correct start value when the DSTC/ESC system is started up. If the normal value has changed during an driving cycle, the value is stored in the EEPROM memory of the Brake Control Module (BCM) after the ignition is switched off. The value is then reloaded to the internal memory when the ignition is switched on. 

HINT: The offset values can also change shortly after the ignition was switched off.
