Turn Signal On
WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
The radio activates the turn signal on audible warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime at a fast rate frequency and a continuous duration. The turn signal on warning sounds when the following occurs:
- The ignition is ON.
- The BCM detects that the turn signal is active for greater than 1.2 km (0.75 ml). The BCM calculates the distance based on a class 2 message from the PCM indicating the vehicle speed.
