Engine Control Module for GM and Chrysler ApplicationsThe Cardone 77-7746 Engine Control Module is a remanufactured ECM built to restore factory-level engine management performance. It is engineered for specific 1987-1988 Chevrolet and Pontiac applications, including the Chevrolet Monte Carlo, Caprice, El Camino, and Pontiac Grand Prix.Cardone remanufactured electronic and powertrain control modules are rebuilt to meet or exceed original equipment performance, with critical components re-soldered or replaced and each unit computer tested for reliability.Key Features Remanufactured Original Equipment-style engine control module for a precise vehicle fit Computer tested for functionality and reliability before release Critical electrical components are re-soldered or replaced during remanufacturing On-car vehicle validation is used to evaluate durability and performance Earth-friendly remanufacturing process reduces raw material and energy use versus new part production Detailed DescriptionCardone 77-7746 is an Engine Control Module (ECM) for select 1987 Chevrolet Caprice, 1987 Chevrolet El Camino, 1987-1988 Chevrolet Monte Carlo, and 1987 Pontiac Grand Prix applications. This module is built for drivers and technicians replacing a failed ECM in GM vehicles that require accurate electronic engine control and proper calibration transfer. This part cross-references Chevrolet 1227746 and Pontiac 1227746 for the same application.The Cardone Engine Control Module line focuses on remanufactured electronic and powertrain control units that are reverse engineered to identify common failure points. That process helps Cardone correct original design weaknesses, rework critical circuitry, and verify operation through automated testing or bench testing depending on the application. For a Chevrolet Monte Carlo ECM replacement or a Pontiac Grand Prix engine control module replacement, the 77-7746 provides a direct-fit service solution.What This ECM Helps Address No-start or hard-start conditions related to a failed engine control module Intermittent drivability problems caused by internal ECM electrical faults Check engine concerns tied to control module failure Loss of proper fuel, spark, or engine management commands Replacement needs after diagnosing poor grounds, wiring issues, or shorted relays/solenoids Installation Notes and Tips Transfer PROM(s)/CALPACK from the original module when required by the application. Perform any relearns required after installation. Before replacing the ECM, verify grounds, power feeds, wiring harness condition, and related relays or solenoids. For Chrysler PCM units with a “V” suffix, VIN programming is required; confirm your application before ordering. For Ford and GM anti-theft or PATS/Passlock concerns, follow the OE service procedure for the vehicle. Quality AssuranceCardone remanufactured control modules are built from original equipment cores, with critical components reworked and each unit tested for electrical performance. The remanufacturing process is designed to restore dependable operation while reducing material and energy use compared with manufacturing a new module.
