Component Inspection

INSPECTION

1. INSPECT DOOR CONTROL TRANSMITTER




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

HINT: When a new or non-depleted transmitter battery is not available, connect 2 new 1.5 V batteries in series. Then connect the leads to the batteries and use them to apply 3 V voltage 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.

OK:
The door lock can be operated via the transmitter.

HINT:
- 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).

b. Inspect the battery capacity.

HINT:
- The battery voltage level (lithium battery) must be checked while the battery is installed in the transmitter (a resistance of 1.2 kOhms is applied to the battery). When the battery voltage level is checked with the battery un-installed, the voltage reading will be more than 2.5 V until the energy 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.




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




3. Connect the tester's positive (+) lead to the positive (+) side of the battery (lithium battery) and the tester's 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: 2.2 V or higher

HINT:
- When the temperature of the battery is low, the inspection cannot be performed correctly.
When the outcome 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 starts 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 or second voltage reading.

6. Disconnect the lead.
7. Set the battery (lithium battery) in the transmitter.
