Remanufactured ECM for Saturn SC2, SL2, SW2Cardone 77-3774F is a remanufactured engine control module for select 1996-1997 Saturn SC2, SL2, and SW2 applications. It is built to restore factory-style engine management performance with vehicle-specific programming requirements that must be completed for proper operation.Key Features Remanufactured Original Equipment-style engine control module for a precise fit Fits 1996 Saturn SC2, SL2, and SW2 with OE number 21023774 Fits 1997 Saturn SC2, SL2, and SW2 with vehicle-specific flash programming required Critical internal components are re-soldered or replaced during remanufacturing 100% computer tested for functionality and reliability On-car validation is used to verify durability and performance Earth-conscious remanufacturing process reduces raw material and energy use versus new part production Product DetailsThe Cardone Engine Control Module line focuses on restoring electronic and powertrain control performance through remanufacturing and testing. For this application, Cardone 77-3774F is engineered to meet or exceed OE performance expectations, with attention to known failure points identified through reverse engineering. This approach helps correct original design weaknesses and supports dependable operation in Saturn SC2, Saturn SL2, and Saturn SW2 models from 1996 and 1997.This part cross-references Saturn 21023774 for the same application.Common Problems This ECM Can Address Engine no-start conditions caused by a failed control module Drivability issues related to incorrect fuel or ignition control Intermittent stalling or rough running from internal ECM faults Check engine light concerns tied to module failure Communication or calibration problems after ECM replacement Installation Notes Fits 1996 Saturn SC2, SL2, and SW2 with OE # 21023774. 1996 applications require vehicle-specific flash programming on or off the vehicle. 1997 Saturn SC2, SL2, and SW2 applications require vehicle-specific flash programming for both on- and off-vehicle installation. Accurate VIN and mileage information are required for programming. On-car programming must be completed after installation to prevent drivability and starting issues. Before replacing the original ECM, inspect grounds, power feeds, wiring harness condition, and related solenoids or relays. Quality AssuranceEach Cardone remanufactured ECM is computer tested, and critical components are reworked at Cardone’s Philadelphia manufacturing plant. The remanufacturing process includes reverse engineering of failed units to identify and address common design weaknesses, helping deliver consistent electronic control performance for Saturn applications.
