Wrench warning light

So i just got my truck back from the shop to get my secondary ignition system worked on. Today, i got in my truck and my wrench light came on. I thought it was odd, so the next time i started my truck up it went away, and i ahve been driving all day and it has not come on again. any ideas what the problem might be?

Back in August my wrench light would come on then I would lose the drive by wire. The truck would idle but when hitting the accelerating nothing would happen. Shutoff/restart would correct it. This started occurring 2-3 times a week and I kept restarting. Then in January it happened; when I restarted the truck the emissions light came on and neither light would go out. I took it to the dealership and they replaced the throttle body and reflashed the PCM. Then a few months later my PCM failed completely and Ford replaced that as well.

I would take it back to the shop (dealership)? and have them check it out.

When they work on the truck at the dealer some of the procedures will throw a code and cause that light to come on. They will usually clear any remaining codes prior to releasing the vehicle back to you. It sounds like you had an ignition code that cleared itself.
