Toyota corolla immo problem

**Kalectro** · 13th July, 2018, 09:45 AM

Hi everyone,
I have a Toyota corolla 1997 that refuse to start with the original key.
I read the eeprom inside the immo box (89780-12030).
I saw that perhaps the dump is corrupted.
I search for another dump and i write the key(tiris format) inside the dump and the car start for 7s and stop.
I don't know what to do.
Can you check the original file for me?
Thanks

Never run across corrupted dump unless someone had a go at it before, check key if transponder read, had a few original keys that transponder fail. can't read the file, unknown version, you need to read as 16bits, maybe you read wrong.

It is the same thing with 16bits read.
I can post the dump who start the vehicule for at least 7s.

You are ok .. because you changed the immo file , Just need to synchronize the ECU and Immo by short pin 13 and pin 4 in the OBD2 for 30 min. after that start the car normally ..
