DOOR CONTROL TRANSMITTER INSPECTION


  1. INSPECT DOOR CONTROL TRANSMITTER

    A0138EZ

    1. Inspect the transmitter operation.


      1. Remove the battery (lithium battery) from the transmitter Click here.

      2. Install a new or normal battery (lithium battery).

        Tech Tips

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

      3. From outside the vehicle, approximately 1 m (3.28 ft) from the driver side outside door handle, test the transmitter by pointing its key plate at the vehicle and pressing the transmitter switch.

        Standard
        The door lock can be operated via the transmitter.

        Tech Tips


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

        • Since the transmitter uses faint electric waves, the operational area may be reduced if noise or strong electric waves occur in the area where the transmitter is used. In some cases, the transmitter may not function.

      4. Install the battery (lithium battery).

    2. Inspect the battery capacity.

      Tech Tips


      • The battery voltage level (lithium battery) must be checked while the battery is installed in the transmitter (a resistance of 1.2 kΩ is applied to the battery). When the battery voltage level is checked with the battery uninstalled, the voltage reading will be more than 2.5 V until the battery has depleted.

      • If the transmitter is malfunctioning, the voltage reading of the energy left in the battery may be inaccurate.


      1. Remove the battery (lithium battery) from the transmitter Click here.

      2. A0138Z3

        Connect a wire to the negative (-) terminal of the transmitter and install the battery.

      3. A0137C2

        Connect the tester side positive (+) lead to the positive (+) side of the battery (lithium battery) and the tester side negative (-) lead to the wire.

      4. Press one of the transmitter switches for approximately 1 second.

      5. Press the transmitter switch again to check the voltage.

        Standard Voltage
        2.2 V or higher

        Tech Tips


        • When the temperature of the battery is low, the inspection cannot be performed correctly.

          When the result of the test is less than 2.2 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 activates and resistance applied to the battery ceases. 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 has just been returned to 18°C (64°F), the voltage may be unusually high for the first one or two voltage readings.

      6. Disconnect the lead.

      7. Set the battery (lithium battery) in the transmitter.
