Key-In-Ignition Warning
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The radio activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a class 2 message to the radio indicating the chime frequency, medium rate and duration, continuous. The key-in-ignition warning sounds when the following occurs:
- The ignition switch is OFF.
- 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.
