Component Description

Part name	Description
Drive mode select switch	Transmits an ON/OFF state signal of STANDARD, SPORT, ECO, or SNOW mode to the A/C auto amp.
A/C auto amp.	Transmits an input signal (ON/OFF state of each mode) received from the drive mode select switch to the TCM, combination meter, 4WAS main control unit, and ADAS control unit via CAN communication.
AV control unit	Transmits an ECO pedal * reaction force setting signal (Standard/Soft/OFF) to ECM via CAN communication. This signal determines reaction force of the accelerator pedal.
TCM	Transmits a state of a mode received from the A/C auto amp. to ECM.
ECM	Receives a ECO mode signal from TCM and controls throttle angle characteristics and torque. Determines reaction force in accordance with the accelerator pedal operation when in ECO mode and transmits an ECO pedal * reaction force control signal to the ADAS control unit. When receiving the ECO pedal * reaction force setting signal (Standard/Soft/OFF) from the AV control unit, ECM updates ECO pedal * reaction force. Furthermore, ECM sends back the received signal to the AV control unit for confirmation. Controls the ECO drive indicator when in ECO mode. The ECO drive indicator turns ON or blinks (with ECO pedal *) according to accelerator pedal operation.
Combination meter	Indicates a mode state on the vehicle information display, based on a mode state signal received from the A/C auto amp. Turns ON or blinks (with ECO pedal *) the ECO drive indicator according to a request from ECM when in ECO mode.
ADAS control unit	Controls accelerator pedal reaction force of the accelerator pedal actuator when in ECO mode, based on an ECO pedal * reaction force control signal received from ECM.
Accelerator pedal actuator	Applies reaction force to the accelerator pedal when in ECO mode, based on an accelerator pedal reaction force control signal received from the ADAS control unit.

* : ECO pedal control is only for vehicles with intelligent pedal (distance control assist).
