Tone Alarm

GENERAL DESCRIPTION CONCERNING THE TONE ALARM

The tone alarm functions are as follows. These functions are controlled by relevant ECUs.






TONE ALARM

IGNITION KEY REMINDER TONE ALARM FUNCTION





When the driver's door is opened with the ignition key inserted in the ignition key cylinder (ignition switch is in the OFF position,) the tone alarm sounds intermittently to indicate that the ignition key has not been removed.

LIGHT REMINDER TONE ALARM FUNCTION





When the taillights or headlights are ON, if the ignition key is removed and the driver's door is opened, a tone alarm will sound continuously to warn that the lights are on. However, if the taillights or headlights have been turned off by the headlight automatic-shutoff function, the tone alarm will not sound.

Seat belt tone alarm function









If any of the following conditions are met with the ignition switch at "ON" or "ST", the ETACS-ECU sounds the tone alarm by using the driver's seat belt switch signal and the vehicle speed signal from the combination meter.

- Sounds the tone alarm for 6 seconds when the ignition switch is turned "ON" with the seat belt switch on (the driver's seat belt is not fastened) (Timer function).
- Sounds the tone alarm 12 cycles (after 0.5 second) if any of the following conditions are met when 60 seconds or more have elapsed since the ignition switch is turned "ON". One cycle consists of 5 seconds "on" and then 3 seconds "off".
1. The vehicle speed has reached 8 km/h (5 mph) while the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON".
2. The seat belt switch has been turned on (driver's seat belt has not been fastened) for at least 10 seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.
NOTE:
Once the tone alarm has sounded 12 cycles, it does not sound again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions is met.

- The tone alarm stops sounding if the ignition switch or the seat belt switch is turned off (the driver's seat belt is fastened) while the timer operation is active.

DOOR AJAR TONE ALARM FUNCTION

The buzzer is sounded 4 times by the ETACS-ECU to warn the driver if any door (including liftgate [ECLIPSE] or trunk lid [ECLIPSE SPYDER]) is open when the ignition is switched ON and the vehicle speed reaches 8 km/h (5 mph) or faster. The buzzer will continue to sound 4 times even if the ignition, door status, or vehicle speed requirements are not maintained.
