Wrench Indicator

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster receives the wrench indicator status from the powertrain control module (PCM) for the electronic throttle control (ETC) concerns and the transmission control module (TCM) for transaxle concerns over the communication network. When a system concern is detected, the PCM or the TCM sets a DTC and sends the instrument cluster a command signal to illuminate the wrench indicator.
