Overspeed Warning (Export)

The radio activates the overspeed warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency of a medium rate and a continuous duration. The overspeed warning sounds when the BCM senses that the vehicle speed is above 120 km/h via a class 2 message from the powertrain control module (PCM). The overspeed warning turns off when the BCM senses that the vehicle speed is below 110 km/h.
