Toyota Camry 2008 Immo problem

[naelraddad]

hi friends i have Toyota Camry 2008 2AZ engine the car starts for one second then stop i checked with diagnostic tool it has only 1 trouble code in engine ecu B2799 engine immobilizer system
there is no trouble codes with immobilizer ecu
i checked wiring between immo ecu and engine ecu and it is ok
i tried to make manual engine ecu ID registration by shorting pin 13 and pin 4 in diagnosis connector without success
the car has 3 keys programmed 2 keys master and 1 sub key i erased the keys and reprogrammed ( programming keys success but still have the immobilizer error code in engine ecu )

Imoo box part No 89780-33150 with eeprom 93c66
Engine ecu part No 89661-33c10 with eeprom 93c86

I attached both eeprom files may you help me to check if the engine ecu is good matched with the immo box or it is need to be matched

any idea will be accepted


King regards
