Scan Tool Data Definition
Scan Tool Data DefinitionBattery Volt (V)
Battery Voltage is an analog input signal read by the ABS (ESP) control module. Certain ABS (ESP) 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 (ESP) control module internal parameter. It is computed by reference pulses from the wheel speed sensor.
Brake
This switch signal informs the ABS (ESP) control module whether the brake is Switch (ON, OFF) 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. (without ESP) Vehicle acceleration is measured by yaw rate / G sensor assembly and output to ESP control module by pulse signal for 4WD vehicle. (with ESP)
