Description And Operation
DESCRIPTION
The actuator is a motor driven unit that engages and disengages the disconnecting stabilizer bar.
The Active Sway Bar System (ASBS) switch is integral to the Auxiliary Switch Bank Module (ASBM) which communicates over Local Interface Network (LIN) to the Body Control Module (BCM). The Body Controller simply gates the switch request to the ASBS module and the Light Emitting Diode (LED) request from the ASBS to the ASBM. There is no functionality in the BCM.
When the stabilizer bar is disengaged/unlocked the LED in the switch will be SOLID. The LED will be OFF when the stabilizer bar is engaged/locked and will not automatically re-disengage without a customer request (switch actuation).
The LED on the switch will flash for the following reasons:
- When the stabilizer bar disconnect or connect is "In Progress" or
- The vehicle speed threshold has been exceeded with stabilizer bar disconnected (when transfer case is 4LO or 4HI)
- The stabilizer bar was previously disconnected (in 4LO/4HI transfer case) and re-connected because transfer case was changed to N
The ASBS module provides status messages which are displayed in the Instrument Panel Cluster (IPC).
The ASBS module receives a switched ignition feed from the RUN/START Relay and a constant B+ feed from the Power Distribution Center (PDC) to the module.
The ASBS module communicates over Controller Area Network (CAN)-C bus.
