How to Engage "Maintenance Mode" on the G3 Prius

this instructions should be an " sticky" on PC

 

...and that's how you do the Hokey Pokey.


In all seriousness, thanks for posting the info!!!

 

Thanks for that!

Just in case it's not dead obvious, what the last line is saying to do is Shut the Car Down.

Just for giggles, it might be good to block the tires before doing this? Just in case.

 

Thanks


iPhone ?

 

i tried the procedure and it didn't work. the engine started when gas pedal pressed before the end of the dance. is it only for the touch screen models?

 

If the engine started, you must have been in READY, not ON. Be sure to follow step #3 exactly as written.

 

You need to push start button twice without foot on brake, at the start.

 

If I remember correctly, on the UK G3 and Prius+, I seem to think it was just turn car on (ready or acc), press setup button on the nav/radio and turn headlights on and off 3 or 4 times, as it is now on the G4.

 

That's how you get into a set of self-check screens for the infotainment system, which always gets new owners excited thinking they've found a secret shortcut to diagnosing the car, until they find out those screens have only to do with the infotainment system. (They do show the 12 V voltage on the vehicle signal check screen, which is sort of useful. And of course, if the infotainment system is what you've got trouble with, they're helpful then.)

Nothing to do with the "maintenance mode" that you use when you need to run the engine steadily for testing purposes.

Also worth knowing: in earlier generations, there was one "maintenance mode" that both ran the engine constantly, and suppressed traction control so you could do dyno tests. In Gen 3 those are split into two separate modes, with two different menu selections in Techstream to enter them. (Without Techstream, they involve different numbers of go-pedal steps in the little dance.)

 

i stand corrected, the procedure worked alright. i'll copy for future reference.

 

Thanks for the info
How much time the maintenance mode takes?

 

I am not sure I understand the question.

The maintenance mode is something you can select if you are going to do any kind of service procedure where you want the engine to continuously run. In maintenance mode, the engine will never stop automatically, but will stay running, for as long as you want. When you power the car off again, the mode is cancelled, so the car will be back in normal operation when next started.

 

One question, Can you use an OBD11 scan tool while in maintenance mode?

 

I would say, why not? Difficult to do real damage with an OBD2 meter.

 

I was in maintenance mode for 3 mins and then the engine stalled out shaking like crazy.I'm at my wits end. Ever hear of that happening?

 

Is there a way to rev the engine while in maintenance mode?

 

Try pushing the gas pedal?
