Axle Lock Switch: 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 (16kph), 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).
