An Expert’s Note on Programming
As a technician with over 20 years of experience, I’ve seen countless issues arise from improperly matched control modules. A generic, un-programmed ECM from a salvage yard might seem like a cheap fix, but it often leads to a cascade of new problems, from security system lockouts to incorrect engine parameters. Our process eliminates that risk entirely. By programming the 2008-2009 Impala Engine Control Module to your specific VIN before it ships, we ensure the computer knows every detail about your car—its engine, transmission, and factory options. This is the key to a successful, lasting repair.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can typically add it as a note during checkout or send it to us in a message referencing your order number.
Is this module truly ‘plug and play’?
Yes, this module is pre-programmed for your vehicle. After installation, you may need to perform a simple security relearn procedure (often called a CASE learn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for your specific model.
Will this fix my specific check engine light code?
This ECM is the correct solution for internal module failure codes, such as P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault). While it can resolve many other issues, it’s always best to have a proper diagnosis to confirm the ECM is the root cause of your problem.
Where is the ECM located on my 2008-2009 Impala?
On the 2008-2009 Chevrolet Impala, the Engine Control Module is typically located in the lower part of the air cleaner box assembly in the engine bay. Always disconnect the battery before attempting to remove or install the module.
Does this fit models other than the Impala?
Absolutely. This 2008-2009 Impala Engine Control Module, part number 12603530, is also a direct fit for a very wide range of other GM vehicles, including models from Buick, Cadillac, Pontiac, Saturn, and GMC.
