WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Position the accessory switch bezel to the
instrument panel.
(2) Reconnect the instrument panel wire harness
connectors to the connector receptacles for the acces-
sory switches and the cigar lighter/power outlet on
the back of the accessory switch bezel.
(3) Position the accessory switch bezel onto the
instrument panel.
(4) Install and tighten the four screws that secure
the accessory switch bezel to the instrument panel.
Tighten the screws to 2 N·m (20 in. lbs.).
(5) Reinstall the center bezel onto the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
CENTER BEZEL - INSTALLATION).
(6) Reconnect the battery negative cable.
AXLE LOCK SWITCH
DESCRIPTION
If 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.
INSTRUMENT PANEL
OPERATION
The Axle Lock switch receives battery current on a
fused B(+) circuit from a fuse in the Power Distribu-
tion 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 momen-
tary 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).

(1) Check the fused B(+) fuse in the Power Distri-
bution Center (PDC). If OK, go to step 2. If not,
repair the shorted circuit or component required and
replace the fuse.
(2) Check for battery voltage at the fused B(+) fuse
in the PDC. If OK, go to step 3. If not, repair the
open B(+) circuit to the fuse.
(3) Turn the ignition to the off position. Disconnect
and isolate the negative battery cable. Remove the
Axle Lock switch. Disconnect the switch harness con-
nector. Check for continuity between the fuse cavity
in the PDC and the Fused B(+) circuit in the switch
harness connector. If OK got to step 4. If not OK,
repair the open Fused B(+) circuit.
(4) Turn the ignition to the off position. Disconnect
and isolate the negative battery cable. Remove the
Axle Lock switch. disconnect the switch harness con-
nector. check for continuity between the switch
ground and a known good ground. If OK got to step
5. If not OK, repair open ground circuit.
