Still the same, no start, put scanner clear the code, car start, when i tack out the scanner from the car it's go off!!!

2) Read the Oki951 as 93C56 16Bit again With UPA, this time i put the file:

Still the same, only start with scanner!!!

3) Tack another GOOD ECU, I did the same, and still the same, car start only with scanner!!!

4) the problem i am a sure is with the IMMO, because when you tack out the battery and put back, you have this problem.

please help me, or give me any suggestion.
thanks in advnce.

I think your car start when you connect the scanner cable that means your car lost the ecu ground or chase ground ,
try to wired the two ground in the car obd connector and start the car

good luck

if you can not repair it
take another immobilizer and replace eprom

I have same problem, car only start when clear errors, but if disconnect immo box after start after some seconds it turn off.
Did you resolve it?

Hello, I had a similar problem. The machine worked only with the scanner, the problem was in synchronization. I overwrote the key with the master pin and it worked. Is there a key to prescribe? I'll give you a master pin.

[Rito]

I made new key from immobilizr, and it start frist time, but after it no more start...
Can give-me master pin? VIN: NLJWVH7HP5Z050044

Thanks
