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 BCM simply gates the switch request to the ASBS module and the 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 on SOLID. The LED will be OFF when the stabilizer bar is engaged/locked and will not automatically 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 disengaged (when transfer case is 4LO or 4HI)
- The stabilizer bar was previously disengaged (in 4LO/4HI transfer case) and reengaged because the 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 B+ from a switched ignition feed and has a connection to ground at all times.
The ASBS module communicates over Controller Area Network - Chassis (CAN-C) bus.
