End Your Engine Troubles and Restore Your GM’s Performance
Is your Chevrolet Impala, Cadillac CTS, or Buick LaCrosse suffering from frustrating and unpredictable engine problems? A persistent Check Engine Light, rough idling, stalling, or a complete no-start condition often points directly to a failing Engine Control Module (ECM). Don’t let a faulty computer keep you off the road. This professionally programmed ECM is the definitive, hassle-free solution to restore your vehicle’s reliability and performance, getting you back behind the wheel with confidence.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing ECM is the most likely culprit. This unit is designed to be the direct solution for these problems:
- Persistent Check Engine Light: Especially with codes like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or other communication errors.
- Engine Stalling or Misfiring: Unexplained stalling at stops or random engine misfires can be caused by incorrect signals from a faulty module.
- Poor Fuel Economy: A malfunctioning ECM can’t properly manage the engine’s fuel-to-air ratio, leading to a noticeable drop in MPG.
- No-Start Condition: The ECM is the brain of the engine; if it fails completely, it can prevent the vehicle from starting at all, even with a good battery and starter.
- Erratic Transmission Shifting: The ECM works with the transmission controller, and a fault can lead to harsh or incorrect gear changes.
This replacement module is the ideal fix for the 2012-2016 Impala ECM 12652814 and is cross-compatible with several other part numbers, ensuring a perfect match for a wide range of GM vehicles.

Expert Diagnostic Tip: Before condemning your ECM, always check the basics! A weak battery, corroded battery terminals, or a bad engine ground strap can cause low voltage issues that mimic ECM failure. Ensure your battery reads above 12.4 volts and all main power and ground connections are clean and tight. This simple check can save you time and confirm that you’re replacing the right part for the right reason.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you. This ECM will arrive flashed to your specific VIN and updated with the latest GM software. In most cases, it is a plug-and-play installation, though some vehicles may require a simple security or CASE relearn procedure that can be performed with a compatible scan tool.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this the correct ECM for my vehicle?
This ECM fits a wide variety of GM models. The best way to confirm compatibility is to match the part number from your original unit to one of the numbers listed (12651994, 12643248, 12652814, AA69). If you are unsure, please contact us with your VIN, and we will be happy to verify the fitment for you.
What is a CASE Relearn and will I need one?
A CASE (Crankshaft Angle Sensor Error) Relearn is a procedure that synchronizes the new ECM with your engine’s crankshaft position sensor. While not required on all models, some vehicles may set a code (P1336) after installation until this quick procedure is completed with a professional scan tool.
What if my original part number isn’t on the list?
GM uses many interchangeable part numbers. If your part number is not listed, please contact us with your VIN and original part number. We can check our extensive database to confirm if this unit is the correct replacement for your vehicle.
