Lights On Warning
WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
The radio activates the lights on warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime of a fast rate frequency and duration (continuous).
The lights on warning sounds when the following occurs:
- The ignition is OFF (key out of the ignition).
- The BCM determines that the driver door is open (signal circuit is low).
- The BCM determines that the headlamp switch is in the park or head position.
