Lets talk push button start

[mikel]

Many of todays late model vehicles come with a push button start system.
They all seem to have some variance on how they work, so lets discuss.

Ford models equipped with push to start are tricky, as some require a single push of the button to engage RUN mode, while others require you to push the button 2x to engage RUN. Best to check the dash for the indication of ACC or RUN to confirm, or if you click it a 2nd time and it shuts the car off, then you only need one click.

GM vehicles with push button start require that you push and HOLD the button for 8-10 seconds to engage RUN mode. Pressing it just once will engage ACC and will eventually time out and can lead to write failures.

On 08-14 Challengers (ONLY), the button is removable, and should be removed when doing any programming in the vehicle. Just pop the button out and insert the key fob and turn it like a traditional key, 2 clicks to the right for RUN mode.

Anything else, (11+Charger, 300, some new Rams, etc), the button should be pressed 2X without using the brake to engage RUN mode for programming, and for any requested Key ON cycle from the tool.

If you have some info about your specific push button equipped vehicle, please feel free to share, especially anyone with a Ford as it would be good to keep track of which ones need one press, and which need 2.

Thanks

We own a 2015 S550 Ford Mustang GT 5.0 Premium Automatic.

The push-to-start functionality in these cars allows you to press the start button to enter accessory mode.

To engage engine start you must press and hold the brake pedal while pressing the start button.

Obviously in both cases you must have the fob inside the car.

I have a 2017 mustang gt manual transmission. You press once to enter accessory mode. The diablosport trinity still won't read the car though.
