Component	Signal description
BCM	Transmits the drive mode switch signal to chassis control module via CAN communication.
ECM	Receives the drive mode signal from chassis control module via CAN communication.
TCM
ABS actuator and electric unit (control unit)
Combination meter
Power steering control module
ADAS control unit 2
AWD control unit

CONTROL DESCRIPTION

OFF-ROAD	Allows for easier driving or starting on a bumpy road surface such as an uneven dirt road or a steep uphill slope or through sand.
SNOW	This mode makes it easier to start and run from snowy roads and frozen roads.
AUTO	This is the default mode and is most suitable for driving.
ECO	Assists the driver's eco-driving. The engine and transmission points are adjusted for improved fuel economy, providing such a driving features as smooth starting or constant cruising.
SPORT	Adjusts the engine and transmission points for a higher response. The setting of the steering system is adjusted to moderately increase steering wheel effort for a sporty feel.

BRAKE CONTROL SYSTEM CHARACTERISTICS

Drive mode select switch	Brake control system status
OFF-ROAD		TCS: TCS allows more wheel spin before decreasing engine torque by engine torque control - later intervention. Brake limited slip differential (BLSD): Quicker activation of brake limited slip differential (BLSD) control in case of split-mu road surface.
SNOW		TCS: TCS allows more wheel spin before decreasing engine torque by engine torque control - later intervention. Brake limited slip differential (BLSD): Quicker activation of brake limited slip differential (BLSD) control in case of split-mu road surface.
AUTO		Normal
ECO		Normal
SPORT		TCS: TCS allows more wheel spin before decreasing engine torque by engine torque control - later intervention. Brake limited slip differential (BLSD): Quicker activation of brake limited slip differential (BLSD) control in case of split-mu road surface.
