Component Identification:

Location
The AIRMATIC with ADS control unit is located on the control unit retaining plate min 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)
