Normal Operation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The wrench warning indicator status information is transmitted to the instrument cluster over the communication network. The powertrain control module (PCM) sends a signal to the instrument cluster to illuminate the wrench warning indicator when an electronic throttle control system concern has been detected.
