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

Inspect the operation of the electrical key transmitter sub-assembly.

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 electrical transmitter from being damaged.

1. Remove the transmitter battery from the door control transmitter housing set (Click here).
   





2. Install a new or non-depleted transmitter 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.) from the driver side outside door handle, test the door control transmitter housing set by pointing its key plate at the vehicle and pressing a door control transmitter housing set switch.
   

   OK:

   The door lock can be operated via the transmitter.
   

   The LED comes on more than once.
   

   HINT:

   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 shortened or the transmitter may not function.
      

Inspect the transmitter 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 electrical transmitter from being damaged.

1. Remove the transmitter 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 (Click here).
   

   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.

2. Carefully extend the lead wire from the position shown in the illustration and install the previously removed transmitter battery.
   

3. Install the transmitter battery.
   





4. Check the transmitter battery voltage.

   HINT:

   Measure the transmitter battery voltage while pressing the lock or unlock switch on the door control transmitter module set sub-assembly (Click here).

   Standard Voltage:

   Tester Connection	Condition	Specified Condition
   Transmitter battery positive (+) - Transmitter battery negative (-)	Engine switch off, all doors closed and lock switch pushed	2.3 to 3.2 V (Refer to waveform)

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