Detailed Product Description

The Cardone 78-5166 ECM is a critical component for Ford Taurus and Mercury Sable vehicles, responsible for managing engine control and powertrain functions. This module interfaces with the vehicle’s passive anti-theft system (P.A.T.S.) where applicable, and requires proper VIN programming to ensure correct operation.
