TURN LIGHT SYSTEM
id091800111900
Purpose
• The turn light system controls the turn lights to flash according to the turn switch operation.
Function
• The front body control module (FBCM) performs control as follows based on the turn light LH or RH signal sent from the start stop unit via the CAN communication.
-
― Period of time turn switch on signal is received is less than 0.7 s: Controls the turn lights to flash 3 times automatically
― Period of time turn switch on signal is received is 0.7 s or more: Controls the turn lights to flash according to the reception period

Operation
1. When the turn switch is moved to the LH or RH position with the ignition switched ON (engine off or on), the start stop unit detects (1) a turn switch LH or RH signal.
2. The start stop unit sends (2) the turn switch LH or RH signal to the front body control module (FBCM) via CAN communication as a turn light LH or RH signal.
3. When the front body control module (FBCM) receives the turn light LH or RH signal, it flashes (3) the turn light (LH) or (RH).
4. When the front body control module (FBCM) receives the turn light LH or RH signal from the start stop unit for less than 0.7 s, it flashes the turn light (LH) or (RH) three times automatically.
5. When the front body control module (FBCM) receives a turn light signal for the opposite side while the turn light (RH) or (LH) is flashing three times automatically, it cancels the current automatic flashing. However, when the front body control module (FBCM) receives the turn light signal for the opposite side for
0.2 s or more, it flashes the turn light while the turn light signal is being received.
