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.
