Scan Tool Data


4WD Control Module







Scan Tool Data Definitions

Accel Position (Accelerator pedal position) (%)

Accelerator pedal opening ratio detected by signal on CAN communication line fed from ECM.

AWD Mode Status

This parameter indicates i-AWD mode according to 2WD/i-AWD switch signal status detected by 4WD control module.

Transfer Oil Temperature (°C, °F)

Transfer oil temperature detected by transfer oil temperature sensor installed in transfer assembly.

4WD Control Drive CUR. (4WD control drive current) (A)

This parameter indicates input current of coupling assembly.

Battery Voltage (V)

This parameter indicates battery voltage detected by 4WD control module.

4WD Unit Temperature (°C, °F)

4WD unit temperature detected by coupling air temperature sensor installed in coupling assembly.

Front Wheelspeed, Rear Wheelspeed (km/h, mph)

Wheel speed is an ESP (R) control module internal parameter. It is computed by reference pulses from the wheel speed sensor.

F-R Wheelspeed Difference (Front-rear wheel speed difference) (rpm)

This parameter indicates rotation difference between front wheel and rear wheel detected by 4WD control module.

4WD Control Duty Ratio (%)

This parameter indicates operation rate of coupling assembly.
