Key-In-Ignition Warning
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
When the body control module (BCM) detects the key is in the ignition and the signal is low with the driver door open, it activates an audible warning. The key-in-ignition chime sounds at the rate of 100 pulses per minute, medium rate chime, until the driver door is closed or the key removed from the ignition switch. The BCM activates the key-in-ignition warning when all of the following occurs:
- The ignition switch is OFF.
- The key-in-ignition switch signal is low.
- The driver door jamb switch signal is low with the driver door open.
