LH-RH Turn Signal/Hazard Indicator

When the multifunction switch is in the LH  or RH  turn position or if the hazard switch is on, the BCM  sends the turn indication status message to the GWM  over the High Speed Controller Area Network 1 (HS1-CAN). The GWM  sends the turn indication status message to the IPC  over the High Speed Controller Area Network 3 (HS3-CAN). Upon receipt of the applicable turn signal on/off data, the IPC  flashes the turn signal indicator on and off.
