PURPOSE: A vehicle code type anti-theft system using a harness wire in the vehicle transmitting codes is provided, which can be installed in the vehicle by a usual user without an additional wiring. CONSTITUTION: The anti-theft system includes an encoder/transmitter(1) and at least one decoder blocking relay(2). The encoder/transmitter generates codes and converts an analog signal to a digital signal to load the signal into a wiring harness(3) in the vehicle. The decoder blocking relay is connected to one point of a power supply circuit(31). When receiving an accurate code, the decoder blocking relay decodes the codes and can make a power supply circuit to start the vehicle. Thus, there is no need to wire an additional wiring harness between the encoder/transmitter and the decoder blocking relay. |
