Restore Your Pontiac’s Brainpower and Performance
Is your 2006-2009 Pontiac G6 suffering from frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition? The Engine Control Module (ECM) is the central computer of your vehicle, and when it fails, it can cause a wide range of perplexing problems. This replacement ECM is the definitive, hassle-free solution to get your G6 running like new again. We take the guesswork and expensive dealership trips out of the equation by professionally programming this module to your car’s specific Vehicle Identification Number (VIN) before we ship it to you. This ensures a seamless installation and restores your vehicle’s factory performance and reliability.

An Expert’s Note on Programming
As a technician with over 20 years on the shop floor, I’ve seen the frustration of installing a computer from a junkyard. The car won’t start, the security system is locked, and it ends with an expensive tow to the dealer. Our pre-programming service is designed to prevent that exact scenario. By flashing the module with your VIN, we are essentially loading your car’s unique DNA into it—the specific calibrations for its engine, transmission, and factory options. This is the critical step that makes this a successful, do-it-yourself-friendly repair, not another headache. This is the single most important factor for a successful ECM replacement.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program or ship your 2006-2009 Pontiac G6 ECM without it. The VIN is typically found on your driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will I need to do anything after I install it?
Yes. After installation, you will need to perform a security relearn procedure, also known as a Passlock or anti-theft relearn. This procedure syncs the new ECM to your vehicle’s security system. It is a simple process that does not require any special tools and typically involves a sequence of turning the key. We include clear instructions to guide you through it.
Is this a brand new part?
This is a high-quality, genuine OEM component that has been meticulously inspected and verified to ensure it meets or exceeds original factory specifications for performance and reliability. It is not a new part, but it is a dependable and cost-effective solution.
How can I be sure my old ECM is the problem?
While the symptoms listed above are strong indicators, it is always best to have a professional diagnosis performed. Key signs of a bad ECM include specific diagnostic trouble codes like P0601 (Internal Control Module Memory Check Sum Error) or a complete lack of communication with a scan tool.
Does this part fit vehicles other than the Pontiac G6?
Yes, absolutely. This ECM, with service number 12602044, is compatible with a very wide range of General Motors vehicles from the mid-2000s, including models from Buick, Cadillac, Chevrolet, GMC, Saturn, and more. The key is to match the service number from your original unit to ensure compatibility.
