Headlamps On Warning Chime

The headlamps on warning chime sounds if the driver door is ajar, the headlamp switch is in the PARK or HEADLAMP position and the ignition is OFF. The headlamps on chime sounds a repetitive chime tone. The IPC receives the position light status, the door status and the ignition mode messages from the BCM over the Medium Speed Controller Area Network (MS-CAN).
