Active Sway Bar System (ASBS) Switch

The ASBS switch communicates over a Local Interface Network (LIN) with the Body Control Module (BCM). The BCM simply gates the switch request to the ASBS module and the LED request from the BCM to the ASBS switch. There is no other functionality in the BCM.

A request to UNLOCK is made by the user by pressing the SWAY BAR button once, but can be cancelled by pressing the SWAY BAR button a second time. The button is a press and release button that simply reports the switch state as "pressed" or "not pressed" to the BCM and does not latch in place when pressed.

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 user request (switch actuation).

The LED on the switch will flash for the following reasons:

• A stabilizer bar disconnect or connect is "In Progress"
• Vehicle speed threshold has been exceeded with the stabilizer bar disengaged (when transfer case is 4LO or 4HI)
• The stabilizer bar was previously disengaged (in 4LO/4HI transfer case) and re-engaged because the transfer case was changed to N
