ENCRYPTED CODE




Four data codes are transmitted when a switch is operated once. The encrypted code for user identification is a combination of 0 and 1, and more than 1 million different combinations are available. To prevent theft by copying signal codes, the data code includes a rolling code with the encrypted code. The rolling code changes each time a signal is sent.

RECEIVER


The receiver is incorporated into the KOS-ECU together with the receiving antenna. The receiver compares the signal which the antenna received from the keyless operation key with the registered encrypted code and the stored code of the receiver, and when they coincided, outputs a signal from the KOS-ECU. By connecting M.U.T.-III to the diagnosis connector, up to four encrypted codes of keyless operation keys can be registered.

KEYLESS ENTRY HAZARD LAMP ANSWERBACK FUNCTION




The hazard answerback function that allows checking the lock/unlock state of the door easily even in the daytime is installed. When the LOCK signal from the keyless operation key is input to 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. Using a customisation function, the hazard answerback can be enabled/disabled (Refer to ).

KEYLESS ENTRY ROOM LAMP ANSWER-BACK FUNCTION




When the LOCK signal from the keyless operation key is input to ETACS-ECU, 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 keyless operation key is input to ETACS-ECU, 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


When none of the doors is opened within 30 seconds after the doors are unlocked by the keyless entry system, ETACS-ECU automatically outputs the door lock signal to lock the doors. This function prevents the doors (including the tailgate) from being unlocked unexpectedly by operation errors. Using a customisation function, the timer lock period can be changed (Refer to ).
