KEYLESS ENTRY SYSTEM <Vehicles without keyless operation system>





The keyless entry system is installed. There are the following features.


DESCRIPTION OF STRUCTURE AND OPERATION



TRANSMITTER



Function
Transmitter operation
System operation
Standard function (lock/unlock)
Press the lock switch once.
All doors (including the tailgate) are locked.
note If the retracting function of the electric folding mirrors is added using a customisation function, it can be retracted in synchronisation with a lock operation.
Press the unlock switch once.
All doors (including the tailgate) are unlocked.
note If the opening function of the electrical folding mirrors is added as an adjustment function, it can be opened in synchronisation with an unlock operation.
Multi mode function
Press the lock switch once to lock all doors (including the tailgate), and within 30 seconds press the lock switch twice consecutively.
The door mirrors are retracted.
Press the unlock switch once to unlock all doors (including the tailgate), and within 30 seconds press the unlock switch twice consecutively.
The door mirrors return to the original position.
Power door locks with selective unlocking
Press the unlock switch once to unlock the driver’s door, and within 2 seconds, press the unlock switch again to unlock the front passenger’s door, rear doors and tailgate.

ENCRYPTED CODE




The figure shows the codes transmitted from the transmitter. Every time the switch is pressed, the data code is transmitted twice. The encrypted code for user identification is a combination of 0 and 1, and more than 1 million different combinations are available. In addition to the encrypted code, the data code contains a rolling code that changes at each transmission, protecting transmission codes from theft by coping.

RECEIVER ANTENNA


The receiver antenna receives the signal from the transmitter and sends the signal to the ETACS.

ETACS-ECU


ETACS-ECU compares the signal the receiver antenna received from the transmitter with the encrypted code registered in it, and when they coincided, operates keyless entry function (door lock, unlock, etc.). By connecting M.U.T.-III to the diagnosis connector, encrypted codes of up to eight transmitters can be registered.

FUNCTION FOR CONFIRMING ETACS-ECU OUTPUT AND OPERATION


The ETACS-ECU outputs LOCK/UNLOCK signal and informs the driver of the keyless entry system operation by flashing the lamp (Answer-back). Using a customisation feature, the flashing patterns for the answer-back function can be changed according to the table below. The initial setting at factory for the answer-back function is as follows: "Hazard warning lamp: LOCK, Flash once, UNLOCK, Flash twice / Room lamp: LOCK, Flash once, UNLOCK, Stay on for 15 seconds." Using a customisation feature, the hazard answer-back function can be changed (Refer to ).

KEYLESS ENTRY HAZARD LAMP ANSWERBACK FUNCTION




When LOCK signal from the keyless entry transmitter is input to the ETACS-ECU, all doors (including tailgate) are locked and the hazard warning lamp flashes once. When UNLOCK signal is input, all doors (including tailgate) are unlocked and the hazard warning lamp flashes twice.

KEYLESS ENTRY ROOM LAMP ANSWER-BACK FUNCTION




When the LOCK signal from the transmitter is input to ETACS-ECU via the receiver antenna, all doors (including tailgate) are locked, and the room lamp is turned off in synchronisation with hazard lamp answerback (when the room lamp is illuminated, the lamp is turned off). Also, when the UNLOCK signal from the transmitter is input to ETACS-ECU via the receiver antenna, all doors (including tailgate) are unlocked, and the room lamp is illuminated for 15 seconds in synchronisation with hazard lamp answerback.

KEYLESS ENTRY TIMER LOCK TIME


If any door is not opened or closed within 30 seconds after the doors (including tailgate) are unlocked by the keyless entry system, ETACS-ECU automatically outputs the door lock signal to lock the doors (including tailgate). This function prevents the doors (including tailgate) from being unlocked unexpectedly by operation errors. Using a customisation feature, the keyless entry timer lock time can be changed (Refer to ).

OPERATION INHIBITION CONDITIONS


The operation of the keyless entry system is inhibited in the following conditions.
