Scan Tool Data Definition
Battery 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 Switch (ON, OFF): This switch signal informs
the ABS (ESP
®
) 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.
(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
®
)
