Frequently Asked Questions
Do I need to send in my old ECM?
No, this is a replacement part sold outright. You do not need to send us your original module.
Is any additional programming required after installation?
No, we pre-program the module to your VIN before shipping. However, depending on your vehicle’s security system, you may need to perform a simple security relearn procedure (often called a key relearn), which typically does not require special tools. Instructions are readily available for this process.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). You can add it to the ‘notes’ section at checkout or reply to your order confirmation email. We cannot ship your order until we receive the VIN.
How can I be sure the ECM is my problem?
While this part resolves many common issues, a professional diagnosis is always the best way to confirm a faulty ECM. Telltale signs include specific diagnostic trouble codes (DTCs) related to internal module failure (like P0601-P0606) or communication loss codes (U-series codes) that point to the ECM as the source.
What part numbers does this 2017 Caprice ECM 12666070 replace?
This module is a direct, interchangeable replacement for several GM part numbers, including 12667002, 12666070, and 12667189, ensuring a perfect fit and function.
