Headlight warning bell not working



byronhunter is correct. The warning chime is a function built into the IPC but its controlled by the BCM. As you can see the troubleshooting guide tries to isolate whether the fault is with one of the functions that is being monitored or whether its a control failure. If its the latter the solution is a replacement BCM. I'm sure I wouldn't buy a new BCM to bring back that annoying "bong bong".
