Keyless Entry: Service Precautions

WIRELESS DOOR LOCK CONTROL SYSTEM

PRECAUTION

1. NOTICES WHEN CHECKING
a. The wireless door lock remote control function operates only when the following 3 conditions are satisfied.
1. All the doors are closed.
2. No key is inserted in the ignition key cylinder.
3. The power door lock system, the power window system and sliding roof system operate normally.

HINT:
- The UNLOCK and PANIC functions operate even when a door is open.
- The UNLOCK and PANIC functions operate even when the key is in the ignition key cylinder. However, these functions are disabled when the ignition switch is turned ON.

b. The wireless door lock remote control 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 some places, the operational area will be reduced due to the vehicle body shape and the influence of the surrounding environment, or the remote control function will only operate partially.
3. Since the transmitter uses faint electric waves, strong electric waves or noise in the frequency used may reduce the operational area or the remote control may not function.
4. When the battery weakens, the operational area is reduced or the remote control may not operate.

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 other trouble.
