DOOR CONTROL TRANSMITTER (w/o Smart Key System): Inspection: Inspection
WARNING: This page is about a different car, the 2012 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT DOOR CONTROL TRANSMITTER
- Inspect operation of the transmitter.
- Remove the battery (lithium battery) from the transmitter. Refer to REMOVAL .
- 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 batteries in series. Then connect leads to the batteries and apply 3 V to the transmitter, as shown in the illustration.
- 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
The door lock can be operated via the transmitter.
The LED comes on more than once.
- The operational area 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 operation area may be shortened or the transmitter may not function.
- Inspect the battery capacity.
- Remove the battery from the electrical key transmitter that does not operate. Attach a lead wire (0.6 mm (0.0236 in.) in diameter or less including wire sheath) with tape or equivalent to the negative terminal. Refer to REMOVAL .NOTE:
Do not wrap the lead wire around a terminal, wedge it between the terminals, or solder it. A terminal may be deformed or damaged, and the battery will not be able to be installed correctly.
- Carefully pull the lead wire out from the position shown in the illustration and install the previously removed transmitter battery.
- Using an oscilloscope, check the transmitter battery voltage waveform.
HINT:
Measure the transmitter battery voltage while pressing the LOCK or UNLOCK switch on the transmitter.
Standard voltage
Item Content Tester Connection Battery positive (+) - Battery negative (-) Tool Setting 0.5 V/DIV., 100 ms/DIV. Condition Engine switch OFF, all doors closed and lock switch pushed Specified Condition 2.2 to 3.2 V (Refer to the waveform) If the result is not as specified, replace the transmitter battery.
- Remove the battery from the electrical key transmitter that does not operate. Attach a lead wire (0.6 mm (0.0236 in.) in diameter or less including wire sheath) with tape or equivalent to the negative terminal. Refer to REMOVAL .
