Restore Peak Performance to Your Vehicle’s Engine
Is your Chevrolet Caprice, or another compatible GM vehicle, suffering from erratic behavior? Issues like a persistent Check Engine Light, unexplained stalling, poor fuel economy, or harsh shifting can often be traced back to a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it falters, the entire vehicle’s performance and reliability are compromised. This replacement Engine Control Module, part number 12617568, is the definitive solution to restore your vehicle’s factory operation and driving confidence.
From the Diagnostic Bay
We had a 2011 Caprice PPV in the shop that was driving the owner crazy. It had intermittent no-start conditions and would occasionally stall at idle, but never threw a consistent code. We checked the fuel pump, ignition system, and wiring harnesses, but everything seemed fine. On a hunch, we monitored the live data from the ECM and noticed the 5-volt reference signal would drop out randomly. After swapping in a known-good, programmed ECM, the problem vanished instantly. It’s a classic case of how a failing module can create ghost-like symptoms that are impossible to pin down without addressing the core component.
Common Symptoms of a Failing ECM
- ✔ Persistent or flashing Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel efficiency
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ No-start or difficult starting conditions
- ✔ Communication errors with diagnostic scan tools
- ✔ Failure to pass emissions testing

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your VIN during checkout, and the module will arrive ready for installation, saving you time and money.
What is a VIN and where can I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. You can typically find it 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.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly in your vehicle. Your order will be held until we receive the necessary information to complete the service.
Is any other procedure required after installation?
In many GM vehicles, a security relearn (also known as a key relearn or anti-theft relearn) procedure is necessary after installing a new ECM. This can typically be done without any special tools and involves a sequence of key turns. Instructions are readily available online or we can assist you in finding them.
Is this compatible with other vehicles besides the 2011 Caprice?
Yes, this ECM fits a very wide range of GM vehicles from approximately 2008-2011, including many Silverado, Sierra, Suburban, Tahoe, and Express models. Please check the detailed fitment list on this page to confirm it is the correct part for your specific year, make, and model.
