Wireless Door Lock Control System On-Vehicle Inspection

Wireless door LOCK / UNLOCK function:
The wireless door lock control function operates only when the following 2 conditions are met.

1. All the doors are closed.
   

2. The power door lock system is functioning normally.
   

   HINT:

   The UNLOCK function operates even when one of the doors is open.

The wireless transmitter operational area differs depending on the situation.

1. The operational area differs depending on the user, the way the transmitter is held and the location.
   

2. In certain areas, the operational area will be reduced due to the vehicle body shape and the influence of the surrounding environment.
   

3. The transmitter's faint electric waves may be affected if the area has strong electric waves or noise. The transmitter's operational area may be shortened 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 transmitter has had prolonged exposure to direct sunlight, such as on the instrument panel, the battery may weaken or other problems may occur.

Make sure the vehicle is in a condition in which the wireless door lock control functions can be operated (see above).

Check the basic functions.

1. Check that the transmitter's LED lights up 3 times when each switch is pressed 3 times.
   

   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 when the LOCK switch is pressed within 5 seconds after performing step above, all doors (including the luggage compartment door) lock.
   

3. Check that when the UNLOCK switch is pressed once, only the designated door unlocks. When the unlock switch is pressed again within 3 seconds, check that all doors (including the luggage compartment door) unlock.
   

4. Check that when the LUGGAGE switch is pressed for 0.8 seconds, the luggage compartment door opens.

Check the chattering prevention function.

1. If a switch is pressed, check that the corresponding operation is performed 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.
   

Check the automatic locking function.
