Left Turn Signal

The IPC illuminates the left turn indicator when the IPC detects a high (voltage) input condition. The indicator turns OFF within 150 milliseconds after the cluster detects the high input is low. If the cluster determines that the turn signal remains ON for more than 1.29 km (0.8 mile), the PC sends a class 2 message requesting the chime to sound. The signal source comes from the exterior lighting system via a discrete input.
