Is Your Vehicle Running Rough? The ECM Might Be the Culprit.
If you’re dealing with a persistent Check Engine Light, poor fuel economy, stalling, or erratic engine behavior in your GM vehicle, a failing Engine Control Module (ECM) is a likely cause. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement ECM, part number 12642927, is the definitive solution to restore your vehicle’s performance and reliability.
Common Symptoms of a Failing ECM
A faulty engine computer can manifest in various ways. If you’re noticing any of the following issues, it’s time to consider a replacement:
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling, stumbling, or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Difficulty starting the engine, or a no-start condition.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Loss of power and poor acceleration.

Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your car. It will arrive ready to install.
What is a VIN and where can I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can typically find it on a plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is any special security relearn procedure required after installation?
In most cases, this module is plug-and-play. However, some GM vehicles may require a simple security relearn procedure to sync the new ECM with the anti-theft system. This can usually be done without any special tools by cycling the ignition key and is detailed in instructions we can provide.
Will this fix my specific problem, like a P0606 error code?
Error codes like P0606 (ECM/PCM Processor Fault) are strong indicators of an internal module failure. While this ECM is the correct component to fix such issues, it’s always best to have a qualified mechanic confirm the diagnosis, as other issues like wiring problems can sometimes cause similar codes.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot program and ship the module without it, as the programming is essential for the part to function in your vehicle. Your order will be placed on hold until the VIN is received.
