Active Damping Sensor - Operation

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, Throttle Position Sensor (TPS), Active Damping System (ADS) Switch, and three active damping sensors.

There are two operating modes of the ADS, Auto and Sport. At each ignition key on cycle, the vehicle defaults to Auto mode. When Sport mode is selected, the suspension 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 settings for maximum vehicle control. The shock absorbers are unique to the ADS. Each shock absorber has a valving unit that is external, but still part of the shock absorber. Inside each valving 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.
