Scan Tool Data Definitions - Antilock Brake System
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 Relay (V):
This parameter indicates the operational condition of the Pump Motor Relay (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):
The G-Sensor converts gravity during the vehicle acceleration/deceleration in to a voltage conditions and controls the ABS for 4WD vehicle.
