GF32.32-P-1010CA Adaptive damping system control unit, component description
- with CODE (483) ADVANCED AGILITY package

Component Identification:

Location
The adaptive damping system control unit is installed under the front passenger footplate.

Task
The adaptive damping system control unit does the following:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Actuating 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 signals from the following components are read via a direct line:
- Left rear level sensor (B22/7)
- Left front level sensor (B22/8)
- Right front level sensor (B22/9)
- Right rear level sensor (B22/10)
- Left front body acceleration sensor (B24/3)
- Right front body acceleration sensor (B24/4)
- Left rear body lateral acceleration sensor (B24/5)

Chassis CAN
The following signals are read in over the chassis CAN:
- Vehicle speed as substitute value, provided by the instrument cluster (A1)
- Circuit status of circuit 61, status of kick down (with transmission 722) and drive variant, provided by CDI control unit (N3/9) (with diesel engines) or by ME-SFI control unit (N3/10) (with gasoline engines)
- Status of vehicle dynamics button (N72/1s23) and body variant, provided by front SAM control unit with fuse and relay module (N10/1)
- Wheel speed, data from yaw rate sensor for lateral and longitudinal acceleration (B24/15), status of service brake and braking torque, provided by Electronic Stability Program control unit (N30/4) (except code (233) DISTRONIC PLUS) or by Electronic Stability Program Premium control unit (N30/7) (with code (233) DISTRONIC PLUS)
- Steering angle and steering angle rate of change, provided by steering column tube module control unit (N80)

Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Component actuation
The components are actuated via the following lines:
^ Direct line
^ Chassis CAN

Direct line
The following components are actuated via a direct line:
- Left front axle front axle damping valve unit (Y51)
- Right front axle front axle damping valve unit (Y52)
- Left rear axle damping valve unit (Y53)
- Right rear axle damping valve unit (Y54)

Chassis CAN
The following components are actuated via the chassis CAN:
- Light-emitting diode (LED) in vehicle dynamics button via instrument panel LIN (LIN 1) by front SAM control unit with fuse and relay module
