Xterra XE 4WD V6-3.3L SC (VG33ER) (2002)
Lateral Accelerometer: Description and Operation
G SENSOR (4WD MODELS)
The G sensor senses deceleration during braking to determine whether the vehicle is being driven on a high coefficient of friction road (asphalt road,
etc.) or a low coefficient of friction road (snow-covered road, etc.). It then sends a signal to the ABS control unit.
This signal is received by the ABS control unit as a variable voltage signal. The input voltage varies from 1.3 Volts ± 0.125 Volts during a hard
deceleration condition, to 2.5 Volts ± 0.125 Volts with the vehicle stopped and to 3.7 Volts ± 0.125 Volts during a hard deceleration in reverse.
