LAMP REMINDER BUZZER FUNCTION



When the ignition key is removed and then the driver’s door is opened with turning ON the tail lamp or the head lamp, the buzzer sounds continuously to warn the driver that the lamp remains ON.

TURN-SIGNAL LAMP OPERATION SOUND FUNCTION <INITIAL SETTING: WITHOUT FUNCTION>



ETACS-ECU buzzer sounds simultaneously with the blinks of the turn-signal lamp and the hazard lamp.
note Using a customisation function, the turn-signal operation sound function can be enabled or disabled (Refer to ).

DOOR-AJAR WARNING BUZZER FUNCTION <INITIAL SETTING: WITH FUNCTION>



If the vehicle speed sent from the engine-ECU via CAN communication exceeds 8 km/h when a door is open for one second or more, the ETACS-ECU makes the door ajar indicator lamp flash 16 times and activates the buzzer (beeping 16 times) to inform the driver that a door is open.
note Using the customisation function, the control content of door-ajar warning buzzer function can be adjusted (Refer to ).

SEAT BELT WARNING BUZZER FUNCTION





With the ignition switch turned to "ON" or "ST" position (IG1: ON), ETACS-ECU uses the signal from the driver’s seat belt switch, passenger’s seat belt switch <double cab>, seat occupancy sensor <double cab> and the vehicle speed signal to sound the buzzer when the following conditions are met. (Timer activation)
· Control only when the ignition switch is ON
    With the driver’s seat belt switch turned ON (the driver’s seat belt is not fastened) or the passenger’s seat belt switch turned ON (the passenger’s seat is occupied and the passenger’s seat belt is not fastened), the buzzer sounds for 6 seconds after IG1 is turned ON.
· Control while driving
    Starting when 60 seconds have elapsed after IG1 is turned ON, if the following conditions are met, with 0.5-second delay, the cycle of 5-second buzzer sounding with 2.8-second interval is repeated for 12 times (timer activation).
    When IG1 is ON and the seat belt switch is ON (the driver’s seat belt is not fastened) or the passenger’s seat belt switch turned ON (the passenger’s seat is occupied and the passenger’s seat belt is not fastened), the vehicle speed reaches 8 km/h.
note
  1. Once 12 times of buzzer soundings are performed, the next sounding of the buzzer is not performed until the vehicle speed becomes 3 km/h or less.
  2. While the timer is activated, when IG1 is turned OFF or the driver’s seat belt switch is turned OFF (the driver’s seat belt is fastened) and the passenger’s seat belt switch is turned OFF (the passenger’s seat is occupied and the passenger’s seat belt is fastened or the passenger’s seat is not occupied), the sounding of the buzzer is stopped immediately.
