STABILIZER BAR, Front

STABILIZER BAR

STABILIZER BAR

The stabilizer bar is on the bottom of the frame rails. Links are connected from the bar to the axle brackets. The stabilizer bar and links are isolated by rubber bushings.

DISCONNECTING STABILIZER BAR

DISCONNECTING STABILIZER BAR

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.

SWAY BAR SWITCH

The OFF ROAD switch pod (1) is located on the instrument panel near the steering column. The switch pod contains a SWAY BAR switch (2) and a AXLE LOCK switch (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 (2) is a momentary switch while the AXLE LOCK switch (2) 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.

STABILIZER BAR

The stabilizer bar is used to control vehicle body roll during turns. The bar helps to control the vehicle body in relationship to the suspension.

DISCONNECTING STABILIZER BAR

STABILIZER BAR FAILSAFE

Stabilizer bar will ENGAGE with the loss of ignition switch, vehicle speed, or stabilizer bar switch signals

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

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

SWAY BAR SWITCH

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.
