Key-In-Ignition Warning

The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and 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. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The BCM determines that the key-in-ignition switch is closed and the signal circuit is low. The IPC receives a serial data message from the BCM indicating the key-in-ignition status.
