Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module, Active Damping Control (ADCM): Operation
The Active Damping Control Module (ADCM) uses the 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 and 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 Active Damping Control Module (ADCM) controls the suspension and ride for the SRT version of this vehicle by adjusting the rebound and jounce of the shock assemblies using the above information and predetermined matrix's for maximum vehicle control. The shock absorbers are unique to the Active Damping System (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 and one in the rear. These sensors measure the plane of the vehicle.
