Key-In-Ignition Warning Chime
WARNING: This page is about a different car, the 2003 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
The key-in-ignition warning feature is controlled by the GEM. The ignition switch and the driver door ajar switches are monitored by the GEM. If the key in ignition is sensed and the driver door is open, the module will process these inputs, and output an audible chime.
