Acoustic indicator

ICM uses the bus messages "Activate front left indicator ON" and "Activate front right indicator ON" to send a bus message to EHU (353) to activate an acoustic signal in the front speakers (266FL/FR). ICM prioritizes all acoustic indicator and warning symbols in the car. If a warning message comes while the direction indicators are active, the direction indicator tone is interrupted while the warning tone is active in the speakers. A warning tone has higher priority than the direction indicator tone.
