Turn Signal On Warning

The radio activates the turn signal on audible warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency and duration (continuous). The turn signal on warning sounds when the following occurs:
^ The ignition is ON.
^ The IPC detects that the turn signal is active for greater than 1.28 km (0.8 miles). The IPC calculates the distance based on a class 2 message from the PCM indicating the vehicle speed.
