Lights On Warning
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The IPC activates the lights on warning as requested by the body control module (BCM). The BCM sends a class 2 message to the IPC indicating the chime frequency (fast rate) and duration (continuous). The lights on warning sounds when the following occurs:
- The ignition is OFF.
- The BCM determines that the driver's door is open (signal circuit is low). The IPC receives a class 2 message from the BCM indicating the door ajar status.
- The IPC determines that the headlamp switch is in the park or head position.
