Greetings. Would like to ask the group if anyone ever had the "tool" icon light up the dash and have mustang engine stall at the same time.happened to my 2014 mustang v6 3.7 had to pull over and restart engine. Tool icon went away and I drove off .thanks for any help. Joe

its the wrench light, it means there is a fault in one of the systems, you have to pull the codes to see what is up

joe2455

Thanks . Yeah took it to ford house.since the tool icon (fault) had gone away after I restarted the engine they were not able to pull up any codes. I would have to get it towed to shop without starting motor back up. Happened twice I'll see what I can do if it happens again

VERY weird...if you get the light and there's NO code logged, it could be a bad ECU. ECU diagnostics see the problem, trip the light, and before it can log the issue it rolls snake eyes and dies. Maybe?

joe2455

Thanks for your comment. Yeah makes sense .also weird that it runs with no problem between occurrences.doesnt seem to matter whether engine is cold or normal temp.been little over a week since last time.been ok so I'll see.but I am goin to research more on icu thanks again

the wrench icon usually only comes up when its a throttle body issue, I.E. the drive by wire system. could have a dead spot in your gas pedal, or your TB motor isn't working properly. any upgrades in those areas? good luck

joe2455

No upgrades but been hearing a lot about throttle body or throttle body controller issues with that fault . Just like you mentioned ,but trying to find a way to verify since ford won't act till they verify that's its bad,running ok right now but I expect to see it again .thanks for your comments.

I had a 2013 F150 with the ecoboost motor and a bad tune from sct and it would throw that wrench up and lack power but a simple key cycle would make it go away. Ended up narrowing it down to the tune making it do that. As custom tune wouldn't do it and stock tune wouldn't do it.
