Restore Your Impala’s Performance and Reliability
Is your 2006 Chevrolet Impala suffering from erratic engine behavior, a persistent Check Engine Light, or even a no-start condition? You’re not just dealing with an annoyance; you’re facing a faulty Engine Control Module (ECM), the brain of your vehicle.

Common Symptoms & Your Solution
A failing ECM can cause a cascade of frustrating and confusing problems. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Unexplained stalling or rough idling
- Poor acceleration and engine performance
- Decreased fuel economy
- Harsh or erratic automatic transmission shifting
- Illuminated Check Engine Light with codes like P0601, P0603, or P0606
- Complete no-start condition where the engine cranks but won’t fire

An Expert’s Note on Programming
As a technician with over two decades of experience, I can’t stress this enough: VIN-specific programming is not optional, it’s essential. Many people are tempted to grab a used computer from a salvage yard, but this often leads to more problems. A module from another vehicle will have the wrong calibration and, more importantly, will trigger the anti-theft system, preventing your car from starting. Our pre-programming service handles all of that for you. We ensure the module is a perfect digital handshake for your car, saving you time, money, and the headache of a car that won’t run.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This ECM arrives at your door fully programmed to the VIN you provide. The service is included in the price. All you need to do is install it. In some cases, a simple security or CASE relearn procedure may be required, which can be done without special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as it is required for the programming process.
Is this a simple plug-and-play installation?
Yes, for the most part. The physical installation involves disconnecting the battery, removing the old module, and plugging this new one in. Once installed, a security relearn procedure may be necessary, which typically involves a sequence of turning the key on and off. We can provide instructions for this simple process.
What if my original part number is different from 12603530?
This module is a direct replacement for a wide range of GM service numbers, including 12590032, 12602044, 12605843, and more as listed in the description. As long as your vehicle and engine are on the compatibility list, this unit will function correctly once programmed to your VIN.
Where is the ECM located on my 2006 Impala?
On the 2006 Chevrolet Impala, the Engine Control Module (ECM) is typically located inside the air cleaner assembly box in the engine compartment. It’s a straightforward location for access and replacement.
