Hi friends,

I have a toyota rav4, it is intermittently not starting due to the immo system as the key led flashes whenever this happens.
anyone know of a solution to set eeprom file to immo off?
I need this to confirm the issue is from immo.

the ecu is Denso 89661-42730
Engine 1.8vvti (1ZZ-FE)
eeprom 93c56 read at x16

I think immo code id stored in address 14-15, 24-25 and 34-35 code {AC 12}
I tried 00 00 code - it wouldnt start and it re coded to AC 12 when i connect back the antenna.
I also tried FF FF Code - it wouldnt start without and with antenna.

any help appreciated. car is here so i can test out different solution.
