Door Control Transmitter: Inspection

1. Remove the battery (lithium battery) from the transmitter (See REMOVAL  ).
2. Install a new or non-depleted battery (lithium battery).

   HINT:

   When a new or non-depleted battery is not available, first connect 2 new 1.5 V batteries in series. Then connect leads to the batteries and use the leads to apply 3 V to the transmitter, as shown in the illustration.

3. In a location that is approximately 1 m (3.28 ft) away from the driver side outside door handle, test the transmitter by pointing it at the vehicle and pressing a transmitter's switch.

   OK: The door lock can be operated via the transmitter. The LED lights up more than once. 

   HINT:

   • The operational area differs depending on the user, the way the transmitter is held and the location.
   • The transmitter's faint electric waves may be affected if the area has strong electric waves or noise. The transmitter's operation area may be reduced or the transmitter may not function.

HINT:

• When checking the amount of energy left in the battery (lithium battery), the battery must be checked while it is installed in the transmitter (a resistance of 1.2 kΩ is applied to the battery).
• If the transmitter is malfunctioning, the voltage reading of the energy left in the battery will be inaccurate.

1. Remove the battery (lithium battery) from the transmitter (See REMOVAL  ).
2. Connect a wire to the negative (-) terminal of the transmitter and install the battery.

3. Connect the tester's positive (+) lead to the battery (lithium battery) and the negative (-) battery lead to the wire.
4. Press one of the switches on the transmitter for approximately 1 second.
5. Press the switch on the transmitter again to check the voltage.

   Standard voltage: 2.5 V or higher 

   HINT:

   • When the temperature of the battery is low, the inspection will not be accurate. When the outcome of the test is less than 2.5 V, conduct the test again after leaving the battery in a place with a temperature of 18°C (64°F) for more than 30 minutes.
   • Read the voltage immediately after the switch is pressed. When 0.8 seconds have passed after the switch is pressed, the automatic power-off function starts and resistance applied to the battery will cease. The voltage of the battery will be 2.5 V or more.
   • Press the switch at least 3 times before reading the voltage. If the battery temperature has just returned to 18°C (64°F), the voltage may be unusually high for the first or second voltage reading.
