Inspection
INSPECTION
PROCEDURE
1. INSPECT TRANSMITTER BATTERY
(a) Inspect the operation of the transmitter.
(1) Remove the battery (lithium battery) from the transmitter (See page ).
(2) Install a new or normal battery (lithium battery). HINT: If a new or normal battery is not available, first connect 2 new 1.5 V batteries in series. Then connect leads to the batteries and apply 3 V to the transmitter as shown in the illustration. |
|
(3) From outside the vehicle, approximately 1 m (3.28 ft) away from the driver side outside door handle, test the transmitter by pointing its key plate at the vehicle and pressing a transmitter switch, or while carrying the transmitter, touch the inside of the handle and pull it.
OK:
The door lock can be operated via the transmitter.
The LED comes on more than once.
HINT:
(b) Inspect the battery capacity.
(1) Remove the battery from an electrical key transmitter that does not operate (See page ).
(2) Attach a lead wire (0.6 mm (0.0236 in.) or less in diameter including wire sheath) with tape or equivalent to the negative terminal.
NOTICE:
Do not wrap the lead wire around a terminal, wedge it between terminals, or solder it. A terminal may be deformed or damaged, and the battery will not be able to be installed correctly.
(3) Carefully extend the lead wire from the position shown in the illustration and install the previously removed transmitter battery.
(4) Using an oscilloscope, check the transmitter battery voltage waveform. HINT: When measuring the battery voltage, bring the electrical key transmitter within the smart key system operating range and operate the lock switch of a door handle to perform the measurement. For the smart key system operating range, refer to System Description (See page ). Standard Voltage:
If the result is not as specified, replace the transmitter battery. Text in Illustration
