Is Your 2010-2011 Impala Running Rough? The PCM Might Be the Culprit.
If your Chevrolet Impala is experiencing frustrating issues like a persistent Check Engine Light, erratic engine performance, poor fuel economy, or even a no-start condition, the problem may lie with a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose.
This is a direct-fit replacement Powertrain Control Module, part number 12597125, for your 2010-2011 Chevrolet Impala. To ensure a seamless installation and restore your vehicle’s factory performance, we program the module specifically to your car’s Vehicle Identification Number (VIN) before it ships. This process loads the latest software updates from GM, correcting common factory issues and ensuring perfect communication between the module and all other vehicle systems. No additional dealership programming is required.
From the Diagnostic Bay
We had a 2011 Impala come into the shop with a complaint of intermittent stalling and a P0606 (Internal Control Module Processor Error) code. The owner had already replaced the spark plugs, ignition coils, and even the fuel pump with no success. The symptoms were sporadic, making them hard to trace. After verifying power and grounds to the module were solid, we knew the issue was internal to the computer. Instead of a costly and time-consuming trip to the dealer, we installed one of our pre-programmed modules. After a quick security relearn procedure, the car started right up and the stalling issue was completely resolved. It saved the customer hundreds of dollars and days of downtime.
Diagnosing a Faulty 2010-2011 Impala PCM
A failing engine computer can manifest in numerous ways. If you’re noticing any of the following symptoms, it’s a strong indicator that your PCM needs attention. A proper diagnosis is key, but these are the most common signs that point directly to a computer-related failure.
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Stored diagnostic trouble codes (DTCs) related to module communication or internal processor errors (e.g., P0601, P0606)
- ✔ Unexplained drop in fuel efficiency
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Harsh or erratic automatic transmission shifting
- ✔ The vehicle cranks but refuses to start
- ✔ Communication issues with diagnostic scan tools
Plug-and-Play Solution with VIN Programming
Getting your Impala back on the road shouldn’t be complicated. Our process is designed to be straightforward. After placing your order, simply provide us with your vehicle’s VIN. Our technicians will use this information to flash the module with the precise calibration for your Impala’s specific engine, transmission, and options. This ensures that once installed, the computer functions exactly as the original did from the factory, but with the benefit of the latest software updates. This is the most reliable way to replace a faulty 2010-2011 Impala PCM.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for the part to function in your vehicle.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The new module bolts in its place. However, a security relearn procedure may be required for the vehicle to start, which can usually be done without special tools.
Will I need to take my car to the dealer after installation?
No. Because we program the module to your VIN before shipping, you will not need to visit a dealership for programming. This saves you significant time and money. The only potential step is a security relearn, which you can often perform yourself.
What if my original part number isn’t an exact match?
This module, service number 12597125, supersedes and replaces several other part numbers. Please check the compatible service numbers list provided in the description. As long as your original number is on that list, this module will work perfectly once programmed to your VIN.
What is a security relearn procedure?
This is a simple procedure that syncs the new PCM with your vehicle’s anti-theft system. It usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. Instructions are widely available online for your specific model.
