Door Control Transmitter (W/O Entry And Start System) Inspection

Inspect the operation of the transmitter.

NOTICE:

When replacing the transmitter battery, before starting work, remove static electricity that has built up in the body by touching, for example, the vehicle to prevent the door control transmitter module set from being damaged.

1. Remove the battery (lithium battery) from the transmitter (Click here).
   





2. Install a new or normal battery (lithium battery).
   

   HINT:

   When 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) 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.
   

   1. The operational area differs depending on the user, the way the transmitter is held and the location.
      
   2. The weak electric waves from the transmitter may be affected if the area has strong electric waves or noise. The transmitter operational area may be reduced or the transmitter may not function.
      

Inspect the battery capacity.

NOTICE:

When replacing the transmitter battery, before starting work, remove static electricity that has built up in the body by touching, for example, the vehicle to prevent the door control transmitter module set from being damaged.

1. Remove the battery from the electrical key transmitter that does not operate (Click here).
   

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 the 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 out 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:

   Measure the transmitter battery voltage while pressing the lock or unlock switch on the transmitter.

   Standard Voltage:

   Tester Connection	Tool Setting	Condition	Specified Condition
   Battery positive (+) - Battery negative (-)	0.5 V/DIV., 100 ms/DIV.	Ignition switch off, all doors closed and lock or unlock switch pushed	2.2 to 3.2 V (Refer to waveform)

   If the result is not as specified, replace the transmitter battery.
