Key-In-Ignition Warning
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a class 2 message to the IPC indicating the chime frequency (medium rate) and duration (continuous). 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 (signal circuit is low). The IPC receives a class 2 message from the BCM indicating the door ajar status.
- The BCM determines that the key-in-ignition switch is closed (signal circuit is low). The IPC receives a class 2 message from the BCM indicating the key-in-ignition status.
