Module, Active Damping Control (ADCM): Operation

The Active Damping Control Module (ADCM) uses the Controller Area Network (CAN) bus to communicate with multiple modules. The ADCM has the following inputs: vehicle speed, Steering Angle Sensor (SAS) position, Accelerator Pedal Position Sensor (APPS), multiple brake event signals, battery voltage, ignition status, active damping system mode selection, and three active damping sensors.

There are three operating modes of the active damping system: Street, Sport, and Track are the standard modes and Drag is available only on demon. At each ignition key ON cycle, the vehicle defaults to Street mode. Each mode selection has unique handling characteristics.

The ADCM controls the suspension and ride for models equipped with the Active Damping System (ADS) by adjusting the rebound and jounce of the shock assemblies using the above information and the predetermined matrix's for maximum vehicle control. The shock absorbers are unique to the ADS. Each shock absorber has a valve unit that is external, but still part of the shock absorber. Inside each valve unit are two solenoids that control the damping valves to alter the ride of the vehicle. The shocks are replaced as an assembly, they cannot be disassembled for repair.

Additionally, there are three active damping sensors; two in the front of the vehicle secured to the left and right lower frame rails near the Front End Module carrier lower brace, and one in the rear secured to a bracket attached to the right lower D-pillar reinforcement gusset. These sensors monitor the vertical plane of the vehicle.
