Cardone 77-7748 Engine Control ModuleCardone 77-7748 is a remanufactured engine control module built for OE-style fit and electronic reliability. It is designed for classic GM and Pontiac applications that require PROM/CALPACK transfer and, in some cases, additional relearns after installation.Key Features Remanufactured ECM for factory-style replacement fit Critical components are re-soldered or replaced during remanufacturing 100% computer tested for function and reliability On-car validation is used to verify durability and performance Earth-friendly remanufacturing process reduces raw material and energy use versus new part production Compatible with applications that use OE number 1227748 Product DetailsThis Cardone Engine Control Module line focuses on restoring proper engine management after an original module failure. The remanufacturing process is based on reverse engineering the failed unit so known design weaknesses can be corrected before the replacement is released. For vehicles such as the Buick Century, Chevrolet Cavalier, and Pontiac Grand Am, the 77-7748 is a direct electronic replacement for the original ECM architecture used in these applications.This part cross-references OE number 1227748 for the same application.

Perform any relearns specified for the vehicle, including theft, crankshaft, or idle procedures if needed. Before replacing the ECM, inspect grounds, power feeds, wiring harness condition, and related relays or solenoids. For Chrysler PCM applications with a V suffix, VIN programming is required; Ford and GM relearn or anti-theft procedures depend on the vehicle and system. Verify the Ford engineering ID or OE module number when cross-checking applications. Quality AssuranceCardone remanufactured electronic and powertrain control modules are built to meet or exceed OE performance targets. Each unit is computer tested, and critical circuitry is repaired or replaced during remanufacturing at Cardone’s Philadelphia facility to support dependable operation in service.
