Hi


I have Toyota Rav4 2003 year 2.0 d. Problem is that car does not start (it crancs mayby for 1 second try to start and stops). DTC is: B2799 (immo). I have two orginal keys but car does not start now (5 days ago started good and now not). Transponder is Tiris 4C When I put first or second key to ignition security lamp does not flash. I check antena and is good too.

I removed Immo Box from car. Ecu immo box is (photo in attached):

Toyota 89780-42050
626172-000
model TYI-1
97RI-012008

Inside is eeprom 93LC66 (dump in attached).
I have tried to add new transponder with Xhorse VVDI2 and Superchip. When I loaded ori dump from 93lc66 eprom to VVDI2 it recognized it with two keys but when I try to load my new file (to check all is ok) with added transponder I got message "version unknow".

I have read with VVDI2 all data from two ori keys:

First key: 00007ECB0998E0000000000ED87E0000 00000000071990D3
Second key: 00007E71A73F6000000000D8C77E0000 0000000006FCE58E

Is it possible to do immo off in this car? If not please help how to add new key and start the car (I have VVDI Superchips)

Regards

car still cranc and does not start. When I put key to ignition lamp from immo system stop blinking. I tried to short OBD pins 4 and 13 but it not help. Still have dtc - B2799. Today I have checked engine ecu and I saw that there is a lot of corossion on four pins and in connector so I think that will be the problem. I will buy second used ecu and will try and will report.

Hi. Problem solved. Car starts. Problem was with ecu (corrosion inside and outside on ecu pins). I changed to second used ecu, made synchro and car started. Regards.
