Switch: Description and Operation
DESCRIPTIONIf equipped, the Axle Lock switch is located in the Accessory Switch Bezel, below the HVAC controls. The switch will activate the Rear Axle locker and Rear/Front Axle locker. The switch is a double-action momentary rocker type. The Axle Lock Switch is secured by a snap fit within the bezel. The axle Lock Switch cannot be repaired and, if faulty or damaged, the entire switch must be replaced.
OPERATION
The Axle Lock switch receives battery current on a fused B(+) circuit from a fuse in the Power Distribution Center (PDC). The switch is grounded at all times. The Axle Lock switch is only operational when the instrument cluster sends an activation signal to the switch logic.
With the transfer case in the 4WD Low Range and the vehicle speed below 10 mph (16 kph), a momentary push to the lower portion of the rocker switch to Lock:
- 1st Push: Rear Axle Locked
- 2nd Push: Rear and Front Axle Locked
Momentary pushes will toggle between Rear Axle Locked or Rear/Front Axle Locked. A momentary push to the upper portion of the rocker switch to "OFF", (both axles unlocked).
