Dear Friend,
You have to locate the OBD2 connector, then has to make a bridge between pin 4 and 13 OBD2, then you can see in the instrument panel light check engine starts flashing. esprar now only 30 minutes, then remove the bridge OBD2 connector and start the engine.
luck

What version is your techstream? seed code must be immediately. these codes are constantly changing.
we need more details of his diagnosis to help.

TOYOTA Techstream V11.10.034, it dont have option to change/read seed code.

Now i used everything (ecu, fuse boxses,keys,start button) from another (working perfect) car. Now is working everything radio, light, heater and so on just the same fault code B2799 LEXUS - Engine Immobilizer Malfunction, and no fuel. Fuel system working fine, when fuel bleeding function is on. I could not find "code box"... How to pair all immobilizer parts... ? I tried that focus 30min...
