C0916Active Roll Stabilisation Rear Actuator Circuit

  • Generic OBD-II code · Chassis
  • Can trigger limp mode
How the car detects it
C0916 has no documented user; it is absent from every accessible list, bulletin and index. It names the rear axle actuator of active roll control. Systems with actuators on both axles split the stabilising torque between front and rear, which also lets them tune self-steering; ZF describes this for its electromechanical roll control. Faults at the rear unit therefore change balance as well as body lean. Bulletins show how carmakers handle such cases under their own codes: Mercedes updated the front and rear roll stabilisation units of 2021 GLE and GLS models whose software could display a warning not to exceed 50 mph, and Land Rover quarantined 2022-23 Range Rover and Range Rover Sport cars whose front and rear roll control modules sometimes failed to initialise, lighting an amber suspension lamp.
