Getting it back together is the chore :)
Wasn't it labelled as "Moderately Difficult"
Very little disassembly is required, only pulling off 2-3 panels--depending upon how you decide to run the wire from EVb to ECU.
I think you have to ask yourself if any tampering with the dash is worth it. There have been numerous posts about dash noise after Toyota has had to do any service that required "popping" dash from it's clips.

I look at it this way:

Since I've disassembled my dash for the EV mod (among other things), I'm now familiar with how it all goes together. If any rattles show up (none have), I'll know where they are and how to get to them.
I am using now the EV switch only for fun. Overwriting the computer functionality, gives you worse MPG. I never let any longer even three bars on the battery in EV mode because aftewards the ICE uses more gas then usually in order to fill up the battery. Just did some tests with the EV and the MPG... :)

Any one who does this on a U.S. auto is taking a risk with their warranty, for very little function (that's an opinion, I'm not an expert or lawyer)
Will we have those who are skeptical and those who are a realist. For those who think that its a chore, warranty, more gas ?? hum anyway then dont buy it. At least there is another meduim to buy parts and those who want to buy it , well Im happy for them.

Why? The program is in there, all we're doing is adding a switch to activate it. Also, the warranty for the battery is the same elsewhere with the EV mode as it is here without it.

"25. Does Toyota support the modification of my Prius to be a plug-in Hybrid and run on electric mode only with a switch?

Any such alterations, modifications or tampering with the vehicle voids the warranty and is likely to be counterproductive for air quality and Prius. durability and safety."

I'm not about to alter my 10 year/150,000 mile warranty on my battery (I'm in MA, a CA emissions state.) I don't know of any country that has that long of a warranty...
ev switch

Please explain how the Japan and Europe versions of the Prius get away with the EV switch. Does Toyota NOT honor their warranty because of this?

Uh, if something is installed by a dealer or at the factory, it generally doesn't void warranty. If you, yourself, go in and start wiring things into the electrical system Toyota has no way of knowing what else you might have cut, pulled, broken or otherwise messed up. Therefore they may assume any subsequent problem is your fault and not the manufacturer's. They cover things the dealer may mess up, but not problems you have induced. It is the same with any car... if you do something to the car other than normal maintenance and it involves hardware, you can void the warranty.

With this car in particular, where you might expect subtle computer/electronics related problems, seems to me that tampering with the electrical system is particularly likely to get you into grey territory. OK, it probably won't affect the warranty on the tires, but a lot of the basic function of the car is controlled by the computer... pulling the wrong wire probably could have rather wide-ranging consequences. For me, it's just not worth the risk.

"Therefore they may assume any subsequent problem is your fault and not the manufacturer's"

They can't ASSUME, they have to PROVE. SOmething hard to do in even small claims court, where the judge will likely give weight to the fact that an identical "mod" is made by the factory itself.

Is it even a "mod"? I would call it "user-installed factory equipment."
That's for a plug-in option. The Prius will not drain the battery if you install the EV switch. It will run the engine when it drops down to 2nd / 3rd bar border. It will turn on the engine if you press the throttle harder.

It's like you guys adding a DRL option to the car cause Canada has it and you don't. How would that void the warranty?
I would expect because it's an option that wasn't offered to us. Like something Toyota would not install on my car!

Hey, dont get mad at me. :shock: I'm just a gentle white bear. :D

This is all just an opinion, I'm not an expert or a lawyer.

If someone does an unauthorized modification, and it voids the warranty, you would have to convince Toyota (or a judge $$$$)...not any of us.
