Stabilizer (Sway) Bar Switch, Front Explanation

FRONT SWAY BAR OPERATION DISCONNECTING
This feature will provide feedback to the driver and be controlled by an electronic module (part of the stabilizer bar) which communicates via CAN C at 500 kbps. The disconnecting stabilizer bar module will read the ignition switch, vehicle speed, transfer case, and stabilizer bar switch messages on the CAN C bus and control the disconnecting stabilizer bar. The module will send a stabilizer bar status message and a lighting message on CAN C.

FRONT SWAY BAR OPERATION FAILSAFE
Stabilizer bar will ENGAGE with the loss of ignition switch, vehicle speed, or stabilizer bar switch signals
FRONT SWAY BAR OPERATION DISENGAGE
The bar will DISENGAGE when ALL the following conditions are met:
vehicle speed under 18 MPH
automatically at speeds over 14 MPH if the switch is in the ON position
transfer case in 4 HI or 4 LO
stabilizer bar switch message received for DISENGAGE
ignition switch in the RUN or START position
no stabilizer bar faults detected

FRONT SWAY BAR OPERATION ENGAGE
The bar will ENGAGE when ANY of the following conditions are met:
vehicle speed is greater or equal to 18 MPH
stabilizer bar switch message received for ENGAGE
transfer case in 2WD or neutral

FRONT SWAY BAR SWITCH DESCRIPTION
The OFF ROAD switch pod (Fig 1) #1 is located on the instrument panel near the steering column. The switch pod contains a SWAY BAR switch (Fig 1) #2 and a AXLE LOCK switch (Fig 1) #3.

The switch pod housing and the push buttons are constructed of molded plastic. Each push button is clearly identified with the appropriate text. The SWAY BAR switch (Fig 1) #2 is a momentary switch while the AXLE LOCK switch (Fig 1) #3 is a rocker type switch.

Panel lamps dimmer controlled illumination lamps integral to the circuit board within the switch provide back lighting for visibility at night, but these lamps are not serviceable. The individual switches in the OFF ROAD switch pod cannot be repaired and are not serviced separately. If any component within the switch pod is ineffective or damaged, the entire switch pod unit must be replaced.

FRONT SWAY BAR SWITCH OPERATION
The disconnecting stabilizer bar system will latch the momentary switch through software for an ignition switch OFF condition if the stabilizer bar was DISENGAGED and the transfer case was in 4LO at ignition switch OFF. Upon ignition switch RUN/START and the transfer case in 4LO, the system checks to verify all conditions to DISENGAGE the stabilizer bar are correct and then DISENGAGE the stabilizer bar without switch input.

FRONT SWAY BAR SWITCH REMOVAL
1. Disconnect and isolate the negative battery cable.
2. Using trim stick (special tool #C-4755, Trim Stick) or equivalent, remove the end cap (Fig 2) #1.
NOTE: The off road switch pod (Fig 3) #1 has 2 upper tabs (Fig 3) #2 and 2 lower tabs (directly below the upper tabs on the pod, not shown in illustration) that must be pushed toward the switch pod to release the pod from the instrument panel.
3. Disconnect the electrical connector (Fig 4) #1.
NOTE: Using trim stick (special tool #C-4755, Trim Stick) or equivalent, pry out on the upper edge of the switch pod on the instrument panel face for tension while releasing the retaining tabs.
4. Using trim stick (special tool #C-4755, Trim Stick) or equivalent, push the outside upper pod retaining tabs (Fig 4) #2 down to release, then the same for the inside upper retaining tab (not shown in illustration).
5. Release the lower retaining tabs (not shown in illustration) in the same manner as the upper retaining tabs (Fig 4) #2 while rotating slightly down and away from the instrument panel.

FRONT SWAY BAR SWITCH INSTALLATION SWITCH
1. Press the switch pod (Fig 1) #1 firmly into the instrument panel opening making sure the retaining tabs seat properly.
2. Attach the electrical connector (Fig 4) #1.
3. Install the instrument panel end cap (Fig 2) #1.
4. Connect the negative battery cable.
