Key-In-Ignition Warning
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) activates the key-in-ignition audible warning. The key-in-ignition warning sounds when the following occurs:
- The ignition switch is in OFF, LOCK or ACCY position.
- The body control module (BCM) determines that the driver's door is open (signal is low).
- The BCM determines that the key-in-ignition switch is closed (signal is low).
