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