Headlamps On Warning Chime

When the driver exits the vehicle with the driver door ajar, the headlamp switch is in the PARK or HEADLAMP position and the ignition is OFF, the BCM sends the headlamp on warning chime message to the IPC through the GWM to sound the headlamps on chime. The headlamps on chime sounds a 1-second chime tone continuously.

The IPC receives the headlamp on warning chime message from the GWM over the HS-CAN3.

The GWM receives the headlamp on warning chime message from the BCM over the HS-CAN1.

When a chime request is received, the IPC sends the IPC chime request message to the ACM or the DSP (with Revel audio system) to sound the chime.
