Key-In-Ignition Warning Chime

The key-in-ignition warning chime warns that the key is still in the ignition lock cylinder when the driver door is ajar (without IA) or that the ignition is in ACC (with IA). The key-in-ignition warning chime sounds when the driver door is ajar, the key is in the ignition lock cylinder and in the OFF/LOCK or ACC position (without IA) or when the ignition is in ACC (with IA).

The key-in-ignition warning chime inputs are:

• Ignition state
• Key-in-ignition switch position to the BCM (without IA)
• Door ajar input from the driver door ajar switch to the BCM
• Key-in-ignition chime request communicated by the BCM to the IPC through the HS-CAN
