Wrangler 4WD L4-150 2.5L VIN P MFI (1998)
Acceleration/Deceleration Sensor: Description and Operation
ACCELERATION SWITCH
Acceleration Switch
The CAB monitors the acceleration switch (G Switch) at all times. The switch assembly contains three mercury switches that monitor vehicle
deceleration rates (G-force). Sudden, rapid changes in vehicle and wheel deceleration rate trigger the switch, sending a signal to the CAB. The switch
assembly provides three deceleration rates; two for forward braking and one for rearward braking. The switch provides an additional vehicle
deceleration reference during 4WD operation. The switch reference signal is utilized by the CAB when all wheels are decelerating at the same speed.
G (Acceleration) Switch
The acceleration switch is located in front of the console/shifter mounted to a bracket on the floor pan.
