Restore Peak Performance to Your GM Vehicle
Is your vehicle suffering from a persistent Check Engine Light, erratic engine behavior, poor fuel economy, or a frustrating no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that governs your engine’s performance. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving you with an unreliable and inefficient vehicle. This genuine used GM Engine Control Module, service number 12669908, is the definitive solution to restore your vehicle’s factory performance and reliability.
Is Your Engine Control Module Failing?
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following issues, your engine computer may be the culprit. Look for these common symptoms:
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication or sensor circuits.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly manage spark and fuel, leading to rough running, stalling, or hesitation.
- ✔ No-Start Condition: A completely failed module can prevent the engine from starting at all, as it won’t be able to manage the essential starting sequences.
- ✔ Poor Fuel Economy: Incorrect fuel mixture and timing calculations can cause your vehicle to consume more fuel than necessary.
- ✔ Transmission Shifting Problems: The ECM works in tandem with the Transmission Control Module (TCM). A faulty ECM can cause harsh shifting, delayed engagement, or incorrect gear selection on some models.
- ✔ Intermittent Electrical Issues: Seemingly random problems with other electronic systems can sometimes be traced back to a failing central computer.

After installing your new ECM, a crucial final step is the “Vehicle Theft Deterrent System Relearn.” This procedure syncs the replacement module with your vehicle’s anti-theft system and ignition keys. Without it, the vehicle will not start. This is a standard security measure on all modern GM vehicles. The relearn procedure typically requires a professional scan tool with GM programming capabilities, such as the dealership’s TIS2Web system or equivalent professional-grade equipment. It is the buyer’s responsibility to ensure this, and other potential relearns (like crankshaft position variation), are completed by a qualified technician.
