Deceleration control	It transmits the brake fluid pressure command signal to the brake booster control unit via ITS communication and performs the brake control.
Accelerator pedal actuation control	It transmits the accelerator pedal feedback force control signal to the accelerator pedal actuator via ITS communication and controls the accelerator pedal in the upward direction.

NOTE: DCA system settings can be changed by using the vehicle settings function in the MULTI AV system.
When the ignition switch is in ACC position, DCA system settings cannot be changed.
