Scan Tool Data Definition

RF Wheel Speed Sensor, LF Wheel Speed Sensor, RR Wheel Speed Sensor, LR Wheel Speed Sensor (km/h)
Wheel speed is an ABS control module internal parameter. It is computed by reference pulses from the wheel speed sensor.

Battery Voltage (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.

Brake Switch (ON, OFF)
This switch signal informs the ABS control module whether the brake is active or not.

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, Outlet Solenoid LF, Outlet Solenoid RR, Outlet Solenoid LR (ON, OFF)
This parameter indicates the operational condition of the outlet solenoid valve.

Pump Motor Driver (ON, OFF)
This parameter indicates the operational condition of the pump motor driver (transistor).

Valve Power Driver (ON, OFF)
ABS control module monitors the supply voltage to solenoid valve power supply driver. If the voltage is supplied, ON is displayed.
