Service Mode for the Prius C with Nav

First Navigation Speed Lock Override (from the PC shop) in a Prius v: SUCCESS! | PriusChat

Close to halfway down the page, there are images of the Prius V headunit. Start reading where it says The instructions say to put the car in ACC-ON, hold down the SETUP button on the head unit, and click your parking lights on and off four times.

 

I know there is something called maintanence mode. You have to hit the power button twice, fully press the gas pedal twice while in P, then shift to N and fully press the gas pedal twice, shift back to P and hit the gas pedal twice. Now hit the power button again while holding the brake to turn the car on. You may want to hold your parking brake. I know that this disables the traction control system, which is rather annoying for snow drifting. You may be able to get into a menu from there?

 

• Start diagnostic mode 15 seconds after turning the ignition switch to ON (READY). Otherwise, some items cannot be checked.

(a) While pressing and holding the "CAR" switch, operate the light control switch: Off → On→ Off → On→ Off → On→ Off.
(b) Diagnostic mode starts and the "Service Menu" screen will be displayed. Service inspection starts automatically and the result will be displayed.

 

Tail?

 

On...

 

Hey, I've tried the steps that wmo168 suggested above (where you press-and-hold "CAR" and flick the lights on-and-off 4 times) and it does get me into the Diagnostic mode for my Prius, but I can't seem to see an option for the "Service" menu when I do that, nor have I found a way to get into it outside of the Diagnostic mode.

I hear it may be possible to disable the Navigation GPS lockout (when moving) through the Service Menu. Has anyone been able to do this / get into the Service menu in any of their Prius Cs?

 

No the lockout is not there in any of the menu


iPhone ?

 

Ahh okay, but I suppose just out of ( morbid?) curiocity is there still a way to get into the Service mode / menu?

 

Instruction is on top of the reply by ztanos


iPhone ?

 

I mentioned I tried that in the first post I made today:

Am I missing something / another post?
