Turn Signal Left On Chime

The turn signal left on or turn signal minder chime uses both odometer and turn signal status messages. The turn signal left on chime sounds a repetitive 1-second chime through the front speakers when the vehicle is driven with the turn signal on for more than 3.2 km (2.0 miles).

The IPC  receives the turn signal status from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM  receives the turn signal status from the BCM  over the High Speed Controller Area Network 1 (HS1-CAN).

When a chime request is received, the IPC  sends the IPC  chime request message to the ACM  and the audio DSP  to sound the chime.
