Keyless Entry: Description and Operation

DESCRIPTION AND OPERATION
- With the driver's and front passenger's doors unlocked, press the LOCK switch of the transmitter, and the door lock signal output (0 V) will be sent from the keyless entry control unit terminal No.12 closing the door lock power relays 1 and 2 to lock the driver's and front passenger's doors.
- While the R.H. and L.H. doors are in the locked state, press the UNLOCK switch of the transmitter once, and the DOOR UNLOCK switch signal (0 V) will be sent from the keyless entry control unit terminal No.14 closing the door lock power relay 2 to unlock the driver's door.
- Under the above-mentioned conditions, further press the UNLOCK switch of the transmitter, and the DOOR UNLOCK signal output (0 V) will be sent from the keyless entry control unit terminal No.13 closing the door lock power relay 1 to lock the front passenger's door.
- When the keyless entry system is operated to turn the driver's door lock switch from the UNLOCK position to the LOCK position, the dome light/foot light blinking signal output (system voltage) will be sent twice from the keyless entry control unit terminal No.11 when the door lock switch is turned from the LOCK position to the UNLOCK position, the lighting signal output (0 V) will be provided for approx. 3 seconds.
- Turn the ignition switch from on to off, and the timer circuit will be activated to keep transistor Tr on for 30 seconds allowing the power window to be opened and closed. Moreover, if the front door is opened, the timer circuit will stop to turn off the transistor Tr. This will prevent the window from being opened and closed.
- If the driver seat side door (or assistant seat side door) is opened and the driver seat side inside lock knob (or assistant seat side inside lock knob) is locked with the key inserted in the ignition switch, the ETACS unit grounds the unlock side circuit of the door lock relay to unlock all doors. This way, failure to remove the key is prevented.

NOTE: The dome light winks or comes on when the dome light switch is in the DOOR interlock position. However, the dome light does not wink while it is ON for 6 seconds after closing the door by ETACS function.

Besides the above-mentioned operations, the keyless entry control unit has the following functions.
- If any door is not opened or closed within 30 seconds from unlocking the door by means of the keyless entry system, the door is automatically locked. In addition, if the cryptographic code other than the code stored in the receiver memory is received 30 times in one minute continuously, operation of the unit is suspended for 10 minutes.
- Operation is also suspended if the ignition key remains inserted (key reminder switch: OFF) and either door is left open (door switch: ON).
