Keyless Entry Transmitter Battery: Testing and Inspection
INSPECTION
1. INSPECT WIRELESS DOOR LOCK TRANSMITTER OPERATION
HINT: Refer to "Wireless door lock control transmitter battery replacement".
a. Using a screwdriver, remove the cover.
b. Remove the battery (lithium battery).
c. 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.
d. In the location where is approx. 1 M away from driver's outside handle in the right direction, and check the transmitter operation when
pressing transmission switch on the side of the transmitter body.
Standard:
Remote control of vehicle door lock can be operated.
HINT: The minimum operation distance differs according to operator, the way of holding the transmitter, and location.
As weak wave is used, operation distance might be shortened when noise is detected in strong wave or used frequency.
e. Install the battery (lithium battery).
f.
Install a cover so that rubber cover is not distorted or slipped off.
2. CHECK BATTERY CAPACITY
HINT:
-
Make sure to use the TOYOTA electrical tester.
With the battery unloaded, 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.
-
On 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 kg).
a. Remove the cover using a (-) driver.
b. Remove the battery (lithium battery) from the transmitter.
c. Connect the lead to the (-) terminal of the transmitter and install the battery.
