An Expert’s Note on VIN Programming
In modern GM vehicles, the ECM is more than just an engine controller; it’s a security hub integrated into the vehicle’s entire network. Simply swapping a used module from another vehicle will almost always result in a no-start condition due to anti-theft system mismatches. Our VIN programming service isn’t just a convenience—it’s a necessity. We ensure the module communicates perfectly with your vehicle’s other systems (like the BCM and instrument cluster) right out of the box, saving you from diagnostic headaches and additional costs.
Frequently Asked Questions
Do I need to do any extra programming after I receive it?
No. This module is fully programmed to your vehicle’s VIN before we ship it. In most cases, it is a direct plug-and-play installation. Some vehicles may require a simple security relearn procedure, which can typically be done without special tools and takes only a few minutes.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or send it to us via email. We cannot ship your part until we receive the VIN, as this is required for the programming service.
My original part number isn’t 12670335, but it’s on your list. Will this work?
Yes. This ECM is a compatible supersession for all the part numbers listed in the description, such as 12668866 and 12643636. As long as your original part number is on our compatibility list, this unit is the correct replacement.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original ECM (common codes P0601-P0606), then this part is the correct fix. However, it’s crucial to ensure your vehicle has been properly diagnosed, as other faulty sensors or wiring issues can also trigger a check engine light.
Is this a difficult part to install?
The physical installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The location varies by vehicle. Because our Programmed 12670335 ECM is pre-flashed, the most complex part of the job is already done for you.
