Keyless Entry System

GENERAL DESCRIPTION CONCERNING THE KEYLESS ENTRY SYSTEM

The following ECUs affect the functions and control of the keyless entry system.






ALL DOOR LOCK FUNCTION

PRESSING THE TRANSMITTER LOCK SWITCH





When the transmitter lock switch is pressed, the ETACS-ECU energizes its door lock relay to operate all the door lock actuators for 0.25 second, locking all doors.

DRIVER'S DOOR UNLOCK FUNCTION

PRESSING THE TRANSMITTER UNLOCK SWITCH ONCE





When the transmitter unlock switch is pressed once, the ETACS-ECU energizes its door unlock relay to operate the door lock actuator of the driver's door for 0.25 seconds, thus unlocking only the driver's door.

ALL DOOR UNLOCK FUNCTION

PRESSING THE TRANSMITTER UNLOCK SWITCH TWICE





When the transmitter unlock switch is pressed twice, the ETACS-ECU energizes its door unlock relay to operate the driver's door lock actuator and the other door lock actuators for 0.25 seconds each in succession. All the doors will be unlocked.
NOTE:
If the timed locking function is available, the doors will be locked in 30 seconds after the initial unlocking. Therefore, the second door unlocking should be done within 30 seconds after that initial unlocking.

KEYLESS ENTRY HAZARD ANSWER BACK AND HORN ANSWER BACK FUNCTION

KEYLESS ENTRY HAZARD ANSWER BACK FUNCTION*1





If the keyless entry transmitter is used to send a lock signal to the ETACS-ECU, all doors and the liftgate are locked and the hazard warning lights flash once. If an unlock signal is sent, the driver's door is unlocked first,*2 and if a second signal is sent, all doors and the liftgate are unlocked. Each time the unlock signal is sent, the hazard warning lights flash twice.
NOTE:
*1: The hazard answer back function can be customized using the keyless entry transmitter (Refer to Enabling/Disabling the Answer Back Function, Keyless Entry System) or by using the multi-center display (middle grade type). Refer to Adjustments.

NOTE:
*2: Vehicles with a multi-center display (middle grade type) can be customized so that a single unlock operation will unlock all doors. Refer to Adjustments.

KEYLESS ENTRY HORN ANSWER BACK FUNCTION





If the keyless entry transmitter is used to send a driver's door lock signal to the ETACS-ECU, the tone alarm sounds when the ETACS-ECU receives the lock signal.
NOTE:
: The horn answer back function can be customized by using the keyless entry transmitter
(Refer to Enabling/Disabling the Answer Back Function, Keyless Entry System) or by using the multi-center display (middle grade type). Refer to Adjustments.

TIMED LOCKING MECHANISM

After unlocking the doors with the keyless entry transmitter, if no doors are opened or if the ignition key is not inserted, the ETACS-ECU automatically locks the doors after 30 seconds.

NOTE:
The timed locking function can be customized on vehicles equipped with a multi-center display (middle grade type). Refer to Adjustments.
