Wireless Door Lock Control System: Specifications Toyota Sequoia I

Check Battery Capacity

Note. Make sure to use the TOYOTA electrical tester. With the battery unloaded, judgement can not be made whether the battery is good or not on the test. When the transmitter is faulty, the energy amount left in the battery might not be read correctly. On the lithium battery used for the transmitter, voltage of more than 2.5 volts 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 k/Ohm).

Scheme 143

1. Remove the cover using a screwdriver.
2. Remove the battery (lithium battery) from the transmitter.
3. Connect the lead to the (-) terminal of the transmitter and install the battery.
4. Connect the (+) tester to the (+) battery (lithium battery), and (-) tester to the lead respectively.
5. Press one of the transmitting switches on the transmitter for approximately 1 second.
6. Press the transmitting switch on the transmitter again to check the voltage. Standard: 2.1 V or more.
7. Disconnect the lead.
8. Set the battery (lithium battery) in the transmitter.
