Lights On Warning

The IPC activates the lights on audible warning as requested by the body control module (BCM). The BCM requests the audible warning when the power mode is OFF, the driver door is open and the discreet park lamp input to the BCM is high. The BCM sends a serial data message to the IPC indicating the chime frequency, rate and duration. The lights on warning sounds when the following occurs:

• The ignition is OFF.
• The BCM determines that the driver door is open.
• The BCM determines that the headlamp switch is in the park or head position.
