ATA Inclination Sensor, Function

The electrodes in the ATA inclination sensor (B33) are partially immersed in an electrolyte (electrically conductive liquid). If the conductive value between the electrodes changes the sensor recognizes a change in the inclination of the vehicle. When the vehicle is parked the value for the vehicle position is stored.

If the vehicle is moved with a certain inclination in longitudinal and/or lateral direction for a certain reaction time when the ATA is activated, the ATA inclination sensor (B33) transmits a signal to the PSE control module (combined) (A37).
