Key-In Ignition Warning

Radio activates key-in-ignition audible warning as requested by Rear Integration Module (RIM). RIM sends a class 2 message to radio indicating chime frequency (medium rate) and duration (continuous). Key-in-ignition warning sounds when this occurs:

• Ignition switch is turned to OFF position.
• Driver's Door Module (DDM) determines that driver's door is open (signal circuit is low). RIM receives a class 2 message from DDM indicating door ajar status.
• Instrument Panel Module (IPM) determines that key-in ignition switch is open (signal circuit is high). IPM receives a class 2 message from RIM indicating key-in ignition status.
