Key-In-Ignition Reminder
WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
The BCM activates the key in ignition audible warning at a medium rate chime frequency (150 pulses per minute) and continuous duration when the following conditions are met:
- The ignition switch is in the OFF or ACC position.
- The BCM determines that the key-in-ignition switch is open (signal circuit is high).
- The body control module (BCM) determines that the driver's door is open (signal circuit is low).
