Scan Tool Data Definition
Scan Tool Data DefinitionBattery Volt (V)
Battery Voltage is an analog input signal read by the ABS control module. Certain ABS control module functions will be modified if the battery voltage falls below or rises above programmed thresholds.
Pump Motor Driver (V)
This parameter indicates the operational condition of the pump motor driver (transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LF Wheel Speed (km/h, MPH)
Wheel speed is an ABS control module internal parameter. It is computed by reference pulses from the wheel speed sensor.
Brake Switch (ON, OFF)
This switch signal informs the ABS control module whether the brake is active or not.
G Sensor (G)
4WD model: Vehicle acceleration is measured by G sensor and output to ABS control module as the linear voltage. 2WD model: Fixed 2.54 G.
Solenoid Valve Power Supply Driver (ON, OFF)
ABS control module monitor the supply voltage to solenoid valve power supply driver. If the voltage is supplied, ON is displayed. Beside, OFF is displayed.
Inlet Solenoid RF, Inlet Solenoid LF, Inlet Solenoid RR, Inlet Solenoid LR (ON, OFF)
This parameter indicates the operational condition of the inlet solenoid valve.
Outlet Solenoid RF, Inlet Solenoid LF, Inlet Solenoid RR, Inlet Solenoid LR (ON, OFF)
This parameter indicates the operational condition of the outlet solenoid valve.
