Lexus gs300 2006, B2799 IMMO Problem cannot FIX Engine start and goes out

VLexus  Lexus gs300 2006, B2799 IMMO Problem cannot FIX Engine start and goes out
The only error in the engine ECU is B2799 Engine Immobilizer Malfunction - no other errors in the all car.


At the moment, everything works like the central and smartkey, the steering lock is working, the engine starts for a few seconds and then goes out.

The connection of the immo line (EFI IMO - two wires) between the ECU and the ID box module is ok.

After trying to start again, the engine cranks but does not start. After the ignition is turned off and the key is pressed, the engine starts but only for a moment


Smartkey, ID BOX, key - i make Virgin and programming again.
Then everything is paired with Techstream, the ECU is paired on the obd jumper - the engine starts and goes out.

I am asking for help, the car has been standing for a long time, I have no ideas anymore. Its very important for me.

Please HELP!!!!
