Turn Signal on -20

The IPC monitors circuit 14 (OK BLU) at connector C1 terminal B12 and circuit 15 (LT BLU) at connector C1 terminal B11. When the left or the right turn signal switch is on the IPC detects a voltage condition. If the circuit remains active for at least 1.6 km (1 mile), the IPC displays this message. Also, the IPC sends a class 2 message requesting the radio to activate a multiple chime.
