I posted this to Green Hybrid and thought it might be useful here too.

Maybe someone will find this useful if it hasn't already been posted. Found this while trying to find a scanner/code reader for the Escape "Wrench" light. Other than Autoenginuity, FORSCAN and IDS, can't find a simple tool that will read Ford specific or enhanced fault/trouble codes. As with others, my wrench light tends to be intermittent. Somehow at one point, I was able to determine I had a bad battery cooling fan. Replaced it and the wrench light went away. Maybe I'm getting the B1239 Battery blend door actuator fault, but don't have a way to pull the DTC's related to the wrench light.

Can't yet post URL links, so you can hopefully get the link I posted on Green Hybrid.
