Cardone 78-1042F Engine Control Module

Cardone ECM for Ford Focus

Cardone Engine Control Module 78-1042F is a remanufactured ECM for select 2006-2007 Ford Focus applications. It is built to restore factory-level engine management performance with vehicle-specific programming requirements noted for this platform.

Key Features

• Remanufactured Original Equipment-style fit for the correct Ford Focus application
• Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant
• 100% computer tested for electrical reliability and function
• On-car validation is used to verify durability and performance
• Earth-friendly remanufacturing process reduces raw material and energy use versus new part production

Product Details

Cardone’s Engine Control Module line focuses on correcting common failure points found in original modules. For this 78-1042F ECM, the remanufacturing process is based on reverse engineering the failed unit so design weaknesses can be identified and addressed. That approach helps deliver a dependable replacement for the Ford Focus engine control system, especially where drivability, starting, or communication faults trace back to the module itself. This part cross-references Ford OE numbers such as 6S4A12A650KA and 6S4Z12A650KA for the same application.

What It Is Used For

• Engine no-start conditions related to ECM failure
• Drivability problems caused by incorrect fuel, spark, or timing control
• Diagnostic trouble codes tied to module communication or internal faults
• Intermittent performance issues from damaged solder joints or worn internal components
• Replacement after confirming the original Ford Focus ECM is the source of the problem

Installation Notes

Compatible With 2006-2007 Ford Focus, N/A, all calibrations with Module ID VH1-S4613. Vehicle-specific flash programming is required on or off the vehicle, and accurate VIN and mileage information are required. On-car programming must be completed after installation to avoid drivability and starting issues. The PATS module requires programming after ECM installation. Verify the Ford engineering ID on the original module before ordering, and inspect grounds, power feeds, wiring harness condition, and related solenoids or relays before replacing the ECM.

Quality Assurance

Each Cardone remanufactured electronic control module is computer tested before release, with additional bench testing or automated testing used depending on application. The remanufacturing process includes re-soldering or replacement of critical internal components to improve electrical connection integrity and reduce intermittent failures. Cardone’s ECM program is built to meet or exceed original equipment performance standards.
