Don't waste your time. This on/off thing is brand specific. It just happens to work on the old Dodge vehicles he owns. And its not even the whole code. That's just a base code. There should be more after the P0456, or whatever that code was. Either way, a scan tool can't tell you what's wrong with a car. You still have to diagnose the problem once you get the code. P0456 is an code that tells you there is a leak in the evap system. It could be a bad gas cap, or a purge valve, a break in one of the lines, etc.... I could list at least 10 more possible causes for that code.

Thank you, even though this process didn’t work on my Buick
I have a 2019 Toyota rava 4 . Have a drive / start detected ?
Can you do it more than once? Did this on my 16 JK but missed the code. Now it won't show the code. Read somewhere else this only works 1 time. Thnx
It should work every time
This didn't work on an 03 Dodge Dakota with a 4.7 Magnum engine. Any idea why?
Would this work on a 2004 Land Rover discovery 2 V8
Will this work on the gmc envoy Guess not 😐

Will this work on a Mitsubishi, 1995 expo
Depending on the year, you may be able to try this while holding down the trip reset button. If not, then you will need a diagnostic reader.

Yes this is a dodge/ christler brand thing. We knew about the key thing back in Obd 1
Only a tiny fraction of vehicles have this function.
Will this work on all vehicles
You’ll have to try it out on yours. On all my cars it works only on Chrysler
@@PhillipsVision thank you
