Remanufactured ECM for GM Trucks and SUVsThe Cardone 77-0279F Engine Control Module is a remanufactured ECM built for 1998-1999 GM and Isuzu applications that require OE-level electronic control and vehicle-specific programming. It is a direct-fit replacement for select Cadillac, Chevrolet, GMC, Isuzu, and Oldsmobile models, including Chevrolet Astro, Tahoe, C/K trucks, and GMC Yukon.Cardone remanufactured engine control modules are reverse-engineered to identify common failure points, then rebuilt with critical components re-soldered or replaced at the Philadelphia manufacturing plant. Each unit is computer tested to verify function before release.Key Features Remanufactured Original Equipment-style ECM for precise vehicle fit Computer tested for functionality and reliability Critical electrical components are re-soldered or replaced during remanufacturing On-car vehicle validation is used to confirm durability and performance Earth-conscious remanufacturing process reduces raw material and energy use versus new part production Detailed DescriptionThis Cardone Engine Control Module, part number 77-0279F, is engineered for direct replacement in select 1998-1999 Cadillac Escalade, Chevrolet Astro, Chevrolet C1500, Chevrolet K1500, GMC Safari, GMC Yukon, and related applications. It is built to restore engine management functions after ECM failure and to support proper drivability once the vehicle is programmed correctly.For Chrysler PCM applications with a “V” suffix, VIN programming is required. For this ECM family, verify the original engineering ID and follow the required flash or on-car programming procedure after installation. Some GM applications also require the knock module to be transferred from the original PCM to the replacement unit.This part cross-references OE numbers 9355699 and 16250279 for the same application.What This ECM Helps Resolve No-start condition caused by a failed engine control module Intermittent drivability problems tied to internal ECM faults Check engine concerns related to electronic control failure Programming-related issues after replacing the original PCM/ECM Vehicle performance problems caused by damaged solder joints or failed internal components Installation Notes and Tips Confirm the OE number and engineering ID before ordering the replacement module. Determine the root cause of the original failure first; common causes include poor grounds, bad wiring harnesses, and shorted solenoids or relays. Perform the required flash programming or on-car programming after installation to avoid drivability and starting issues. Accurate VIN and mileage information are required for vehicle-specific programming on listed applications. Follow an OE-approved service manual for programming, anti-theft reset, and relearn procedures where required. Quality AssuranceCardone remanufactured electronic and powertrain control modules are built to meet or exceed OE performance targets. Each unit is tested with automated computer equipment or bench-tested, depending on application, to confirm operation before it leaves the manufacturing process.
