Location
The active roll stabilization control unit is located in the control unit box under the left front seat.
Tasks
The active roll stabilization control unit regulates the hydraulic oil flow of the hydraulic pump, the oil pressure in the hydraulic system of the Active Roll Stabilization and the rotation direction of the hydraulic front axle stabilizer actuator and the hydraulic rear axle stabilizer actuator.
Input and output signals
The following input signals are evaluated by the active roll stabilization control unit and the corresponding output signals output:
- Direct input and output signals
- Chassis CAN 1 (CAN E1)
Direct input signals

Chassis CAN 1
The active roll stabilization control unit communicates via chassis CAN 1 with the following control units:
- Instrument cluster (A1), via chassis CAN 2 (CAN E2) and the electronic ignition lock control unit (N73)
- Electronic ignition switch control unit
- CDI control unit (N3/9) or ME-SFI control unit (N3/10)
- Fully integrated transmission control unit (Y3/8n4), via the drive train CAN (CAN C) and chassis CAN 1 using the CDI control unit interface (with diesel engine) or ME-SFI [ME] control unit interface (with gasoline engine)
- Steering column tube module control unit (N80)
- SAM control unit (N10), via the interior CAN (CAN B) and electronic ignition lock control unit
- Electronic Stability Program control unit (N30/4)
- Transmission modes control panel (N72/4) over the chassis CAN 1, electronic ignition lock control unit, the interior CAN, the SAM control unit and the center console switch LIN (LIN B12)
- Transfer case control unit (N15/7) (with CODE 430 (On-road & off-road package)), via the drive train CAN and chassis CAN 1 using the CDI control unit interface (with diesel engine) or ME-SFI [ME] control unit interface (with gasoline engine)
- AIRmatic control unit (N51/3) (with CODE 489 (AIRmatic))
- Trailer recognition control unit (N28/1) (with CODE 550 (Trailer hitch)), via the interior CAN and the electronic ignition lock control unit
The active roll stabilization control unit receives signals from the following sensors and buttons via chassis CAN 1:
- From the left front axle rpm sensor (L6/1), right front axle rpm sensor (L6/2), left rear axle rpm sensor (L6/3) and right rear axle rpm sensor (L6/4), read in by the Electronic Stability Program control unit
- From the steering wheel angle sensor (N49) over the steering column tube module control unit
- From the transmission mode control (N72/4s1) transmission mode control panel (N72/4) over the center console switch LIN and the interior CAN to the electronic ignition lock control unit with the SAM control unit interface. The electronic ignition lock control unit sends the signal via chassis CAN 1 to the active roll stabilization control unit.
System diagnosis takes place via the diagnostic connector (X11/4) using Xentry Diagnostics.
