Remanufactured ECM for Ford Bronco II and RangerThe Cardone 78-4324 Engine Control Module is a remanufactured electronic and powertrain control module built to restore factory-level engine management. It is pre-programmed at the factory for the listed Ford applications and is backed by computer testing for reliable operation.Compatible with 1986 Ford Bronco II and 1986 Ford Ranger with Federal Emission System, this ECM is a direct-fit replacement for vehicles using ID # E6PF-AA. The Cardone engine control module line focuses on remanufactured OE-style electronics that are validated for fit, function, and durability.Key Features Remanufactured Original Equipment-style ECM for precise vehicle fit Factory pre-programmed for the listed Ford applications Critical components are re-soldered or replaced during remanufacturing 100% computer tested for function and reliability On-car validation is used to confirm durability and performance Earth-friendly remanufacturing process reduces raw material and energy use versus building a new part Detailed Product InformationCardone part number 78-4324 is engineered for Ford engine management systems where the original module has failed or become unstable. The remanufacturing process includes reverse engineering to identify common failure points, then correcting those weaknesses with repaired or replaced critical circuitry. This helps deliver consistent electrical performance in applications such as the 1986 Ford Bronco II and 1986 Ford Ranger.This part cross-references Ford OE numbers such as E6PF12A650AA and E6PZ12A650AA for the same application.Common Problems This ECM Can Address No-start condition caused by a failed engine control module Intermittent stalling or rough running from unstable module output Check engine concerns related to ECM internal failure Driveability issues after the original module has been damaged by electrical faults Problems traced to incorrect fuel or ignition control signals Installation Notes and TipsBefore replacing the original ECM, verify the root cause of the failure. Common causes include poor grounds, power supply issues, damaged wiring harnesses, and shorted solenoids or relays. For Ford applications, confirm the engineering ID on the original module matches the correct Cardone number before installation. Some Ford vehicles require a PATS reset, but not all do; check the correct PATS chart for the application.For 1986 Ford Bronco II and 1986 Ford Ranger, this module is pre-programmed at the factory. Chrysler PCM units with a V suffix require VIN programming, and GM vehicles may require Passlock or Passkey/VATS reset procedures when applicable.Quality AssuranceEach Cardone remanufactured ECM is computer tested, and applications may also receive bench testing or on-car validation depending on the design. The remanufacturing process is performed at Cardone’s Philadelphia manufacturing plant, where critical components are repaired or replaced to help restore dependable operation.
