Key-In-Ignition Warning

The radio activates the key-in-ignition audible warning as requested by the driver integration module (DIM). The DIM sends a class 2 message to the radio indicating the chime frequency of a medium rate and at a continuous duration. The key-in-ignition warning sounds when the following occurs:

• The ignition switch is OFF.
• The driver integration module (DIM) determines that the driver door is open and the signal circuit is low.
• The DIM determines that the key-in-ignition switch is closed and the signal circuit is low.
