Audible Warnings: Key-In-Ignition

Radio activates key-in-ignition audible warning as requested by Body Control Module (BCM). BCM sends a class 2 message to radio indicating chime of a medium rate frequency and a continuous duration. Key-in-ignition warning sounds when the following occurs:

• Ignition switch is in LOCK position.
• BCM determines that driver door is open and signal circuit is low.
• BCM determines that key-in-ignition switch is closed and signal circuit is low.
