System Inspection

INSPECTION




1. INSPECT WIRELESS DOOR LOCK TRANSMITTER OPERATION
a. Remove the battery (lithium battery) from the transmitter.
b. Install a new or normal battery (lithium battery).

HINT: When a new or normal battery can not be obtained, connect 2 new 1.5 V batteries in series, connect the battery (+) to the battery receptacle side terminal and battery (-) to the bottom terminal, then apply 3 V voltage to the transmitter.

c. In the location that is approx. 1 m (3.28 ft) away from driver's outside handle in the right direction, face the key plate of the transmitter to the vehicle, and check the transmitter operation when pressing a transmission switch on the transmitter body.

Standard: The remote control of vehicle door lock can be operated.

HINT:
- The minimum operation distance differs according to the operator, the way of holding, and location.
- Since weak wave is used, the operation distance might be shortened when noise or strong wave is detected in the area where the frequency is used.

d. Install the battery (lithium battery).

2. CHECK BATTERY CAPACITY

HINT:
- With the battery unloaded, the judge can not be made whether the battery is available or not on the test.
- When the transmitter is faulty, the energy amount left in the battery might not be checked correctly.
- For the lithium battery used for the transmitter, the voltage more than 2.5 V with the battery unloaded is shown on the tester until the energy is completely consumed.
Accordingly when inspecting the energy amount left in the battery, it is necessary to measure the voltage when the battery is loaded (1.2 kohm).

a. Remove the battery (lithium battery) from the transmitter.




b. Connect the lead to the (-) terminal of the transmitter and install the battery.




c. Connect the (+) tester to the (+) battery (lithium battery, and (-) tester to the lead respectively.
d. Press one of the transmitting switches on the transmitter for approx. 1 second.
e. Press the transmitting switch on the transmitter again to check the voltage.

Standard: 2.2 V or more

HINT:
- When the temperature of the battery is low, the judge can not 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 at 18 °C for more than 30 minutes.
- By automatic power off function, the voltage becomes no load voltage (more than 2.5 V) condition after 20 seconds from the switch is pressed.
Make sure to read the voltage just after the switch is pressed.
- Since high voltage might be shown once or twice after the battery is left, the judge should be made with the voltage shown at the 3rd time or later.

f. Disconnect the lead.
g. Set the battery (lithium battery) in the transmitter.
