Remanufactured Engine Control Module for Ford, Lincoln, and MercuryThe Cardone 78-4325 engine control module is a remanufactured ECM built for specific 1986 Ford, Lincoln, and Mercury applications. It is engineered to restore factory-style engine management performance for vehicles such as the 1986 Ford LTD, Lincoln Town Car, and Mercury Grand Marquis without California Emission System equipment.Key Features Remanufactured Original Equipment-style engine control module for exact vehicle fit Reverse-engineered to identify and correct original design weaknesses Critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant 100% computer tested for reliability and function On-car vehicle validation is performed to verify durability and performance Earth-friendly remanufacturing process reduces energy and raw material use versus building a new part Product DetailsCardone’s Engine Control Module line focuses on restoring electronic and powertrain control performance with remanufactured OE-style parts. Part number 78-4325 is built for direct replacement in the listed 1986 Ford, Lincoln, and Mercury applications, including the Ford LTD, Lincoln Town Car, and Mercury Grand Marquis. This part cross-references Ford applications such as E6SF12A650ARA and E6SZ12A650ARA for the same application.For Chrysler PCM units with a “V” suffix, VIN programming is required. For Ford applications, not every vehicle needs a PATS reset; verify the correct procedure for the specific vehicle. If a GM PCM is replaced, Passlock or Passkey VATS reset procedures may be required. Before replacing any ECM or PCM, confirm the original failure source, including grounds, power supply, wiring harness condition, and shorted solenoids or relays.Common Problems This ECM Can Address No-start condition related to a failed engine control module Intermittent drivability issues caused by internal ECM faults Communication or control problems tied to damaged electronic components Performance issues from original module design weaknesses Failure after electrical stress, poor grounds, or harness-related damage Installation Notes and TipsVerify the Ford engineering ID number on the original ECM or PCM before ordering to confirm the correct Cardone 78-4325 replacement. This module is pre-programmed at the factory for the listed 1986 applications, but the installer should still inspect vehicle grounds, power feeds, and related wiring before installation. If the vehicle uses anti-theft or programming procedures, follow the OE service manual for the exact reset or relearn steps.Quality AssuranceEach Cardone remanufactured engine control module is computer tested, and applications may also receive bench testing or on-car validation depending on the vehicle. The remanufacturing process includes re-soldering or replacement of critical components to improve electrical integrity and long-term reliability.
