Cardone 77-9463F Engine Control Module

Remanufactured ECM for GM Trucks and SUVs

The Cardone 77-9463F Engine Control Module is a remanufactured ECM built for select 2005-2006 Chevrolet, GMC, and Hummer applications. It is engineered to restore factory-style engine management performance for vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Hummer H2 when the original module has failed.

Cardone remanufactured electronic and powertrain control modules are reverse engineered to identify common failure points, then corrected during the remanufacturing process. Each unit is computer tested for functionality, and critical components are re-soldered or replaced at Cardone’s Philadelphia manufacturing plant.

Key Features

• Remanufactured Original Equipment-style ECM for a direct vehicle fit
• Computer tested or bench tested, depending on application
• Critical components are re-soldered or replaced to improve electrical integrity
• On-car vehicle validation is used to verify durability and performance
• Earth-friendly remanufacturing process reduces raw material and energy use versus new part production

Product Details

This Cardone Engine Control Module, part number 77-9463F, is built for vehicles that require OE number 12589463 and flash programming after installation. Fitment includes the 2005-2006 Chevrolet Avalanche 1500, Silverado 1500, Suburban 1500, Tahoe, GMC Sierra 1500, Yukon, Yukon XL 1500, and Hummer H2, plus 2005 Chevrolet Silverado 1500 HD, Silverado 2500 HD, Silverado 3500, Suburban 2500, GMC Sierra 1500 HD, Sierra 2500 HD, Sierra 3500, and Yukon XL 2500. This part cross-references Chevrolet 12589463 for the same application.

Common Problems This ECM Can Address

• Engine no-start condition after ECM failure
• Intermittent drivability concerns tied to module faults
• Communication or control issues caused by damaged internal circuitry
• Check engine light concerns related to ECM malfunction
• Starting and performance problems after a failed original control module

Installation Notes and Tips

• Vehicle-specific flash programming is required on or off the vehicle.
• Accurate VIN and mileage information are required for programming.
• On-car programming must be completed after installation to avoid drivability and starting issues.
• Before replacing the original ECM/PCM, inspect grounds, power feeds, wiring harness condition, and shorted solenoids or relays.
• For Chrysler PCM units with a “V” suffix, VIN programming is required; some Ford and GM applications may also require security system resets depending on the vehicle.

Quality Assurance

Cardone remanufactured control modules are reverse engineered to address original design weaknesses and are tested to confirm reliable operation. The remanufacturing process includes re-soldering or replacing critical components and validating the unit with computer-based testing or bench testing, depending on application.
