DOOR LOCK: WIRELESS DOOR LOCK CONTROL SYSTEM: OPERATION CHECK

OPERATION CHECK

1. FUNCTIONS AND OPERATING CONDITIONS
(a) The wireless door LOCK/UNLOCK function:
This function operates only when the following 3 conditions are met:
(1) There is no key in the ignition key cylinder.
(2) All the doors are closed.
(3) The power door lock system is functioning normally.
HINT: The UNLOCK function operates even when any of the doors are open.

(b) Remote panic function:
This function operates only when the following condition is met:
(1) The ignition switch is OFF.
HINT: The key can be inserted.
However the ignition switch must be OFF.

(c) The wireless transmitter operational range differs depending on the situation.
(1) The operational range differs depending on the user, the way the transmitter is held and the location.
(2) In certain areas, the operational range will be reduced due to the vehicle body shape and the influence of the surrounding environment.
(3) Since the transmitter uses weak radio waves, the operational range may be reduced or the transmitter may not function if interference or stronger radio waves occur in the area where the transmitter is used.
(4) When the battery is low, the operational range is reduced and/or the transmitter may not function.
HINT: If the transmitter has been left in a place that is exposed to direct sunlight, such as on the instrument panel, the battery may be weakened or other problems may occur.

2. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
HINT:
- The switches built into the door control transmitter send radio waves to the door lock control receiver.
- The operational range must be taken into account during checks.

(a) Establish conditions that allow the wireless control function to be operated successfully.
(b) Check the following basic functions.
(1) Check that the transmitter's LED lights up 3 times when each switch is pressed 3 times and that the LED blinks when each switch is pressed and held down.
HINT: If the LED does not illuminate when the switch has been pressed 3 times or more, the battery may be depleted.
(2) Check that all the doors lock when the LOCK switch is pressed.
(3) Check that the driver's door unlocks when the UNLOCK switch is pressed once, and all the doors unlock when pressed twice within 3 seconds.
(c) Check the automatic lock function.
(1) Check that if the driver's door or all doors are unlocked with the UNLOCK switch and none of the doors are opened or locked within approximately 30 seconds, the doors automatically re-lock.
(2) Check that if the driver's door or all doors are unlocked with the UNLOCK switch and a door is opened or locked within approximately 30 seconds, the automatic lock function does not operate.
(d) Check the illuminated entry function.
HINT: Turn the interior light switch to the DOOR position before the check.
(1) Check that the interior light comes on simultaneously with the unlocking operation when the UNLOCK switch is pressed.
(2) Check that the interior light goes off in approximately 15 seconds if none of the doors is opened after the unlocking operation.
(e) Check the answer back function.
(1) When the doors are locked by wireless operation, the hazard warning lights flash once.
(2) When the doors are unlocked by wireless operation, the hazard warning lights flash twice.
(f) Check the switch operation fail-safe function.
(1) Check that the doors cannot be locked by operating a switch while the key is in the ignition key cylinder.
HINT: This check cannot be made when the system is in recognition code registration mode.

(g) Check the chattering prevention function.
(1) Check that the corresponding operation occurs only once, and does not repeat itself while the switch is kept pressed. Check that the corresponding operation is carried out when the switch is operated repeatedly at 1-second intervals.
(h) Check the door ajar warning function.
(1) Check that the buzzer sounds when the LOCK switch is pressed when any of the doors are ajar. When all the doors are closed or when the UNLOCK switch is pressed, the buzzer will stop after it sounds for 10 seconds continuously.
(i) Check the panic alarm function.
(1) Check that the following alarms operate for 60 sec. when the PANIC switch is pressed longer than about 0.8 seconds or more:

- The vehicle horns sound.
- The hazard warning lights, headlights and taillights flash.
(2) Check that during the panic alarm is operating, pressing any switch of transmitter cancels the alarm operation.
