Component Inspection

INSPECTION

1. INSPECT TRANSMITTER SUB-ASSEMBLY MODULE SET DOOR CONTROL




a. Inspect operation of the transmitter.

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 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. 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 a transmitter switch.

OK: Door lock can be operated via transmitter. LED illuminates more than once.

HINT:
- The operating range 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 operating range may be reduced or the transmitter may not function.

b. Inspect the battery capacity.

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 kOhm is applied to the battery). When the battery energy is checked by itself (uninstalled), the voltage reading will be more than 2.5 V until the energy is depleted.
- 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.
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's positive (+) side and the tester's negative (-) 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: 2.2 V or higher

HINT:
- When the temperature of the battery is low, the inspection cannot be made 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 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 has just been returned to 18 °C (64 °F), the voltage may be unusually high for the first or second voltage reading.

2. INSPECT INNER REAR VIEW MIRROR ASSEMBLY (DOOR CONTROL RECEIVER)




a. Disconnect the I19 mirror connector.
b. Measure the resistance and voltage of the wire harness side connector.




If the result is not as specified, repair or replace the harness and connector.

c. Reconnect the I19 mirror connector.
d. Measure the voltage of the connector.




If the result is not as specified, replace the inner rear view mirror.

3. INSPECT WIRELESS DOOR LOCK BUZZER




a. Measure the resistance between terminals 1 and 2 of the buzzer.

Standard: Approximately 1 kOhm

If the result is not as specified, replace the buzzer.

NOTE:
- The buzzer circuit is built into the theft warning ECU, not into the buzzer itself.
- When battery voltage is directly applied to the buzzer, the buzzer does not sound.
