The manual isn't much help, at all:
MODULE, ACTIVE DAMPING CONTROL (ADCM)
DESCRIPTION
Vehicles equipped with Active Damping Suspension (ADS) have an Active Damping Control Module (ADCM).
The ADCM (3) is located in the left side of the trunk and is retained by four mounting screws (2). The carpet on
the left side of the trunk has to be repositioned to access the 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, Throttle Position Sensor
(TPS), Active Damping System (ADS) input switch, and 3 acceleration sensors. There are solenoid-controlled
ADS valving units on each shock absorber assembly which are the outputs for the ADCM.
The ADS input switch is a soft touch button on the radio display. When the ADS input switch is pressed with the
key in the ON or RUN position, a signal is sent over the CAN bus to the ADCM and the Transmission Control
Module (TCM) to change modes. The resulting change is indicated on the radio display.
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 Active Damping
System (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.
The two front acceleration sensors are mounted with one on each wheel well. The rear acceleration sensor is
mounted in the right rear wheel well on the shock tower. The ADCM is located in the left side of the trunk.
