Components Function Description

COMPONENTS FUNCTION DESCRIPTION CHART

Component parts	Function
AWD control unit	Controls driving force distribution by signals from each sensor and switch from rear wheel driving mode (0:100) to AWD mode (50:50). 2WD mode is available by fail-safe function if malfunction is detected in AWD system.
Wheel sensors	Detects wheel speed.
AWD solenoid	Controls electric controlled coupling by command current from AWD control unit.
Electric controlled coupling	Transmits driving force to front final drive.
SNOW mode switch	Able to select AUTO or SNOW mode.
AWD warning lamp	Illuminates if malfunction is detected in electrical system of AWD system. There is 1 blink in 2 seconds if rotation difference of front wheels and rear wheels is large. There are 2 blinks in 1 second if load is still applied to driving parts.
ABS actuator and electric unit (control unit)	Transmits the following signals via CAN communication to AWD control unit. Vehicle speed signal Stop lamp switch signal (brake signal)
ECM	Transmits the following signals via CAN communication to AWD control unit. Accelerator pedal position signal Engine speed signal
Combination meter	Transmits conditions of SNOW mode switch and parking brake switch via CAN communication to AWD control unit.
