Immobilizer emulator enabling unlocking engine controllers with the first-generation Toyota system implemented.

In this system, keys/transponders are saved in ECU ,and communication with the ECU takes place over 3 lines:

CODE, RXCK, TXCT.

In order to use this device, the TEXAS 4C transponder code must be rewritten from the ECU or immobiliser module to the 24C02 memory fitted on the emulator PCB.

The connection must be made in accordance with the diagrams available for the vehicle being repaired; the vehicle electronics workshop must have these diagrams.

With the help of this emulator we eliminate :

• Lost key with transponder.
• Defective RFID key reader.
• Faulty wiring harness from the key reader to the ECU.
