B3000 SE Regular Cab 2WD V6-3.0L OHV (2002)
Acceleration/Deceleration Sensor: Description and Operation
G-Switch
^
The G-switch is used on 4x4 vehicles only.
^
The G-switch detects and indicates to the 4WABS control module that the vehicle is moving.
^
Without the G-switch, the control module would have no data to compare and would react as if the vehicle were stopped when in fact it is moving.
