An ACDelco Professional, premium aftermarket Remanufactured Engine Control Module is the ideal high quality replacement for your GM vehicle. It regulates various parts of your vehicles engine by taking the inputs from sensors and additional modules and referencing that information back to other sensors, modules, and other areas of the vehicle. Remanufacturing the engine control module is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are 100% end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing also benefits the environment by returning components back into service rather than processing as scrap or simply disposing of them. This engine control module is manufactured to fit your specific GM vehicle and will provide the same performance, durability, and service life you expect from ACDelco.
Don't Misdiagnose Your ECM! Misdiagnosing an ECM is expensive and time consuming. Before assuming the ECM is at fault, follow these diagnostic steps:
| CHECK ECM INPUTS |
A weak or dead battery is the leading cause of improper ECM function. If the ECM is not receiving enough power (9-12 volts):
- Use a Battery Tester to test Battery voltage output (12.6 volts, with the engine off)
- Check wiring / function of Sensors, Ignition Switch and Fuses
SOLUTION: Replace Faulty Input
|
| VISUALLY INSPECT ECM |
Voltage overload and moisture / corrosion are leading causes of ECM failure. Visually inspect the ECM for:
- Burnt / Melted plastic - often caused by voltage overload from a shorted Solenoid
- Moisture / Corrosion - often due to a faulty Seal, Wiring Harness or extended exposure to the elements
SOLUTION: Replace ECM and fix source of failure |
Locate Your OE Number
Some vehicles may have several ECM replacement options, while others may just have one. Do not assume that any option listed for your vehicle will fit! The most accurate way to order the correct replacement ECM is to verify the OE number provided in the part listing or at the bottom of this page matches the OE number printed on the original unit. If the original ECM no longer has the label, the dealership can look up the OE number using your VIN.
