Frequently Asked Questions
Is this ECM truly ready to install when it arrives?
Yes. As long as you provide your vehicle’s VIN during checkout, we will program the module before shipping. In most vehicles, this allows for a direct installation without any further procedures. However, some models may require a simple security or crankshaft position sensor relearn procedure, which can be performed with a capable scan tool.
How do I provide my VIN number?
You can add your 17-digit Vehicle Identification Number (VIN) in the notes section during the checkout process. If you forget, we will contact you via email after your purchase to request it. We cannot ship your part until we have the VIN to program it correctly.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, this part will resolve the issue. It’s crucial to ensure your vehicle’s issues have been properly diagnosed before ordering. This Programmed 12652814 ECM is designed to fix problems originating from the computer itself, not from other faulty sensors or wiring on the vehicle.
What does the programming include?
The programming service includes flashing the module with the correct, most up-to-date OEM software calibration file from General Motors that matches your vehicle’s specific VIN. This ensures all factory settings for your engine, transmission, and options are correctly loaded.
What if I have another issue after installation?
First, ensure all connections are secure. If problems persist, it may indicate another issue with the vehicle (e.g., wiring, sensors). Our one-year replacement warranty covers the module itself, and our team is available to help guide you through basic troubleshooting steps.
