Wireless Door Lock Control System
OPERATION CHECK1. FUNCTIONS AND OPERATING CONDITIONS
a. Wireless door LOCK / UNLOCK function:
This function operates only when the following 3 condition are met.
1. No key is inserted into the ignition key cylinder.
2. All the doors are closed.
3. The power door lock system and the back door power window control system operate normally.
HINT:
- The UNLOCK and PANIC function operates even when a door is open.
- The UNLOCK and PANIC function operates even when the key is inserted into the ignition key cylinder, however the ignition switch must be in the OFF position.
b. The transmitter's operational area differs depending on the situation.
1. The operational area differs depending on the operators and the ways the transmitter is held.
2. In certain areas, the transmitter will only operate partially, the operational area will be reduced due to the vehicle body shape and the influence of the surrounding environment.
3. Since the transmitter uses faint electric waves, strong electric waves or noise in the frequency used may reduce the operational area or the transmitter may not function.
4. When the battery weakens, the operational area is reduced or the transmitter may not function.
HINT: If the door control transmitter has been left in a place that is exposed to direct sunlight, such as on the instrument panel, it may cause the battery to weaken or cause other such problems.
2. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
HINT:
- The switches described below transmit signals and are built into the door control transmitter.
- The transmitter's operational area must be taken into account while checks are being made.
a. Make sure the vehicle is in the initial condition described below.
1. The followings are the vehicle's initial condition.
- No key is in the ignition key cylinder
- All the doors closed
- The power door lock system and the back door power window control system operate normally.
b. Check the basic function.
1. Check whether the LED of the transmitter lights up 3 times when each switch is pressed 3 times.
HINT: If the LED does not light up when the switch has been pressed 3 times or more, it may have a dead battery.
2. In the operational area, check that all the doors lock when pressing the LOCK switch (However, this will not happen when the key is in the ignition key cylinder or any door is open).
3. In the operational area, check that the only driver's door unlocks when pressing the UNLOCK switch and pressing the switch once again within 3 seconds unlocks all the other doors.
HINT: The UNLOCK and BACK WINDOW operation is possible even when any of the doors is open.
4. In the operational area, check that the power windows open when the UNLOCK switch has been pressed and hold (However, this will not happen when the ignition switch is turned ON).
- Check that the front power windows open when the UNLOCK switch is pressed and held for 2.5 seconds.
- When the UNLOCK switch is continuously held longer, check that the rear power windows and sliding roof open.
HINT: The above 2 operations should be continuously performed.
- Check that all power windows and sliding roof stop operation when the UNLOCK switch is released.
c. Check the chattering prevention function.
1. If a switch is pressed, check that the corresponding operation occurs only once. If the switch is held down, check that the corresponding operation occurs only once and does not repeatedly activate. Lastly, if a switch is pressed at 1 second intervals, check that the corresponding operation activates once for every press of the switch.
d. Check the automatic locking function.
1. Check that if all of the doors are unlocked with the UNLOCK switch and none of the doors are opened or locked within approximately 30 seconds, the doors automatically relock.
2. Check that if all of the doors are unlocked with the UNLOCK switch and a door is opened or locked within approximately 30 seconds, the automatic locking function does not operate.
e. Check the switch operation fail-safe function.
1. Check that when the key is in the ignition cylinder, the switches cannot lock or unlock doors (unless the system is in the recognition code registration mode.)
f. Check the repeat function.
1. If the lock switch is pressed while the movement of the driver side door control knob is restricted, check that, 1 second later, the repeat function attempts to lock all of the doors again.
g. Check the operation stop function when a door is open or not completely close.
1. If a door is open or not completely closed, check that the doors cannot be locked by the LOCK switch and buzzer sounds for 10 seconds.
h. Check the hazard warning lights flashing and wireless door lock buzzer sounding function (answer back).
1. When the LOCK switch is pressed, check that the hazard warning lights flash once and the buzzer sounds once, simultaneously with locking operation of all the doors.
2. When the UNLOCK switch is pressed once, check that the hazard warning lights flash twice, the buzzer sounds twice, simultaneously with the unlocking operation of the driver side door.
3. When the UNLOCK switch is pressed again within 3 seconds, check that the hazard warning lights flash twice, the buzzer sounds twice, simultaneously with the unlocking operation of all the doors.
i. Check the remote panic function.
1. Check that the horns sounds, headlights and taillights flash and the interior light remains on for 60 seconds when the PANIC switch is pressed for 0.8 sec., and that sounding and flashing stop when either of the PANIC, LOCK or UNLOCK switch is pressed (However, this will not happen when the ignition switch is turned ON).
