Does anyone have any idea on how to reprogram a replacement ECU on a 2000 Toyota Rav4 ACA21 2 liter 4 cylinder?
I replaced the original 89661-42700 with an 89661-42702 which are supposed to be interchangeable and have since discovered that you have to reset and program it to the original key code?
Is there a particular code that I need to use or even a manual way this can be done without having to use a diagnostic machine?
I would greatly appreciate any help anyone can share? :?
