Acceleration/Deceleration Sensor: Description and Operation

G SWITCH (ACCELERATION SWITCH)

DESCRIPTION
The G-switch is located in front of the console/ shifter mounted to a bracket on the floor pan. The switch has directional arrow and must be mounted with the arrow pointing towards the front of the vehicle.

OPERATION





The switch, provides an additional vehicle deceleration reference during 4-wheel drive operation. The CAB monitors the acceleration switch at all times. The switch reference signal is utilized by the CAB when all wheels are decelerating at the same speed. The switch assembly contains three mercury switches that monitor vehicle deceleration rates (force). Sudden, rapid changes in vehicle and wheel deceleration rate trigger the switch, sending a signal to the CAB. The switch assembly responds to three deceleration rates; two for forward braking and one for rearward braking.
