Key in Ignition Warning
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. 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 body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency of a medium rate and a continuous duration. 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 and the signal circuit is low.
- The BCM determines that the key-in-ignition switch is closed and the signal circuit is low.
