Turn Signal Left On Chime

The IPC  uses both odometer and steering wheel switch turn signal messages to control the turn signal left on chime. The IPC  receives the steering wheel switch turn signal message from the BCM  and the odometer message from the PCM. When the vehicle is driven with the turn signal on for more than 193 km (2.0 miles), the IPC  sounds a repetitive 1.0 second chime.
