Bought a 2012 4Runner that had that installed. Supposedly not active, but I got the Toyota electric manual and removed the damn thing.
If I knew it had one I would have done the same I never knew they had them.
The newer cars and trucks have record what the auto was doing before a wreck speed brakes ..........
Insurance companies pushed that idea I will never buy a new car again it better and cheaper to buy a restored car lower maintenance and it hold it’s value and more fun to drive and better made than a factory built one.
No CPU no metric no problem
