MODEL No.: TWC1U283

The radio frequency keyless entry system has the following functions.

1. Locking and unlocking the doors without mechanical key.

2. Sounding a panic alarm during vehicle is not running.

This system consists of RF Tuner, transmitters, and BCM.

The RF Tuner (EUT) is supplied 5V from BCM. It is designed to operate on

a single fixed frequency RF 315MHz by amplitude modulation. It receives

unique identification code and function code transmitted from transmitters.

After receiving RF signal, demodulation IC in Tuner demodulates RF signal

from transmitters. And then driving circuit in Tuner outputs the

demodulated signal to BCM.

・Basic specifications

 Operating supply voltage 4.5V ~ 5.5V

 Operating supply current < 12mA

 Stand-by current < 1.0mA

 Operating ambient temperature -40

C to +85
