Keyless Entry Transmitter: Testing and Inspection

DOOR CONTROL TRANSMITTER MODULE

INSPECTION

1. INSPECT DOOR CONTROL TRANSMITTER MODULE SUB-ASSEMBLY
a. Inspect the operation of the transmitter.
1. Remove the battery (lithium battery) from the transmitter.




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

HINT: If a new or normal battery is not available, connect 2 new 1.5 V batteries in series. Connect the positive (+) battery electrode to the battery receptacle side terminal, and the negative (-) battery electrode to the bottom terminal, and apply a voltage of 3 V to the transmitter.

3. In a location that is approximately 1 m (3.28 ft.) away from the driver side outside door handle, point the key plate of the transmitter at the vehicle and check the operation of the transmitter by pressing the transmission switches on the transmitter body.

OK:
The door lock can be operated via remote control.
The LED lights up more than once.

HINT:
- The minimum operational distance differs depending on the operator, the way the transmitter is held, and the location.
- Since the transmitter uses faint electric waves, the operational distance might be shortened if noise or a strong electric wave occurs in the area.
