Fits 2002-2004 Ford F-250 Super Duty, N/A. Fits 2002-2004 Ford F-350 Super Duty, N/A. Verify the Ford engineering ID on the original module before ordering. Confirm the correct VIN and OE number, then complete the required flash programming after installation. Check grounds, power feeds, wiring harness condition, and related solenoids or relays before replacing the ECM. Some Ford applications require a PATS reset; verify the vehicle-specific procedure for your application. Quality AssuranceCardone remanufactures this ECM using reverse engineering to identify original failure points and correct design weaknesses. Critical circuits are reworked at the Philadelphia manufacturing plant, and each unit is computer tested to verify operation before shipment. The remanufactured process also reduces energy and raw material use compared with producing a new part.
