Wrench Indicator

WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster receives the electronic throttle control (ETC) status from the PCM over the communication network. When a system concern is detected, the PCM sends the instrument cluster a command signal to illuminate the wrench indicator.
