Dynamic Drive (ARS) consists of the following components:

ARS Control Module:  The control module is located on the right side "A" pillar in front of the glovebox and is powered by B+ through a 10 Amp fuse. The control module is activated by a CAN alarm lead from the CAS module when the ignition is switched "ON".

A vehicle authentication process takes place when the system is started. This compares the vehicle identification number from CAS with the vehicle identification number which is encoded in the ARS control module.

After the ignition is switched "ON", the ARS hardware and software is self-checked. All of the outputs (magnetic valves) are checked for short circuits and breaks. When there is a fault, ARS switches the actuators to a safe driving condition. The control module will switch off in the event of undervoltage or overvoltage.
