Remanufactured Engine Control ModuleCardone 78-4288 is a remanufactured engine control module built for direct replacement in select Ford trucks and SUVs. It is engineered to restore proper engine management, with factory-style fitment for applications such as the 1985 Ford Bronco and 1985-1986 Ford F-150.Key Features Remanufactured original equipment-style ECM for a precise vehicle fit Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant 100% computer tested for electrical function and reliability On-car vehicle validation is used to verify durability and performance Earth-friendly remanufacturing process reduces energy and raw material use versus building a new part Product DetailsThe Cardone Engine Control Module line focuses on restoring OE-level performance through reverse engineering and component-level correction of known failure points. For this application, Part Number 78-4288 is listed for 1985 Ford Bronco, 1985 Ford F-250, 1985 Ford F-350, and 1985-1986 Ford F-150 with Federal Emission System and ID #(s) E5DF-HA. This part cross-references Ford E5DF12A650HA and E5DZ12A650HA for the same application. If you are replacing an ECM on a Ford F-150, Bronco, F-250, or F-350, verify the engineering ID on the original unit before ordering.Common Problems This Part Can Resolve No-start or hard-start condition caused by a failed ECM Driveability issues tied to incorrect fuel or spark control Intermittent stalling from internal module faults Check engine concerns related to control module failure Problems traced to damaged solder joints or failed internal electronics Installation Notes and TipsBefore replacing the original ECM, inspect grounds, power feeds, wiring harness condition, and any shorted solenoids or relays that could have caused the failure. For Ford applications, confirm the engineering ID on the module matches the correct Cardone number. This unit is pre-programmed at the factory for the listed applications. If the vehicle still does not start after installation, verify the original module diagnosis and check for PATS-related concerns where applicable.Quality AssuranceCardone remanufactures this Engine Control Module to meet or exceed OE performance expectations. Each unit is computer tested, and the remanufacturing process includes re-soldering or replacement of critical components to improve electrical integrity and long-term reliability.
