Key-In-Ignition Warning
WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The BCM activates the key-in-ignition audible warning as requested by the ignition key alarm switch. The key-in-ignition warning sounds when the following occurs:
- The ignition switch is OFF.
- The body control module (BCM) determines that the drivers door is open (signal is low).
- The BCM determines that the key-in-ignition switch is closed (signal is low).
