500x stop nd start

Post by Younes »

Does MultiEcuScan support disabling Start & Stop on a 2024 Fiat 500X 1.4 MultiAir?

Not that I can see directly as a function.

My 2015 500X has a button on the dasboard to disable the Start / Stop.

I guess coould be done via custom Proxi change but I've not ever seen any details here.

You could disconnect the battery sensor module. After some time the S / S will probably stop working as it can't determine the condition of the battery from the measured charge / discharge profiling. HOWEVER! Doint this could affect the alternator charging if your 500X has a smart alternator.

Disconnecting the battery sensor plug makes the Start/Stop warning light turn on. This is very annoying and could be harmful to the car's systems.
In the free version of the software (using Simulator mode), I couldn't find the option to disable this feature.
Does this mean the option is not available at all, or is it just hidden in the free version?

I have the full version of MES.

The free version will show all that is available but you won't will only be able to use those functions.

Does this mean the Start/Stop disable feature for the 500x is also missing from the full version?
wiTECH doesn't support these adjustments, even with the latest update. So, I’m planning to use MES. I need to be sure it can disable Start/Stop on the 500x before purchasing


Thank you

As I said (maybe I was not clear) the free version shows everyting that is available in the purchased version. I can NOT see any Start/Stop setting in the latest version of MES for the 500X.

I've had comments from a Fiat Master Technician the wiTECH does not support some items that MES does.

Check Out AlfaOBD as well.

You could also contact MES Spport with a Pre-Sales enquiry.

Usually disabling start stop requires a visit from the ECU tuner.
