Location
The AIRMATIC with ADS control unit is located on the control unit retaining plate in the front passenger footwell.
Task
The tasks of the AIRMATIC with ADS control unit are as follows:
- Reading in of sensors, pickups and signals
- Evaluation of input factors
- Actuation of components
Reading in of sensors, pickups and signals
The input factors are read in with the following connections:
- Direct line
- Chassis CAN (CAN E)
Direct line
The following components are read in via a direct line:
- Rear axle level sensor (B22/3)
- Left front level sensor (B22/8)
- Right front level sensor (B22/9)
- Left front body acceleration sensor (B24/3)
Right front body acceleration sensor (B24/4)
Right rear body acceleration sensor (B24/6)
AIRmatic pressure sensor (Y36/6b1)
Chassis CAN
The signals are read in by the AIRMATIC with ADS control unit via the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Evaluation of input factors
The input factors are evaluated by the microprocessor and the corresponding components are actuated.
Actuation of components
Components are actuated with the following connection:
- Direct line
Direct line
The following components are actuated via a direct line:
