Ive got a 2006 gen 2 prius with around 600K KM.
So i was driving when out of nowhere the red triangle showed up, a friend with a computer wiped it off and i was good for another 6 months, now it started showing up again and sometimes it doesnt let me put it in gear, ive changed the battery changed the ventilator and still nothing, same fault and it doesnt show the exact location of the fault (like 611 612 613 etc.) Has anyone had this before or know how to fix it?
