B4000 Regular Cab 4WD V6-4.0L OHV (1997)
Lateral Accelerometer: Description and Operation
The G-switch is used on 4x4 vehicles only. When driven in the 4-wheel drive mode all four wheels are mechanically linked and a situation could arise in
which one wheel locks up and causes all four wheels to lock up and skid. The speed sensors would indicate the vehicle speed as zero. Without the
G-switch, the anti-lock brake control module would have no data to compare and would react as if the vehicle were stopped when in fact it is moving.
The G-switch detects and indicates to the anti-lock brake control module whether or not the vehicle is moving.
