Do I need to have this ECM programmed by a dealer?
No. We program the module to your specific VIN before we ship it. It will be ready to install in your 2007 Sierra 1500 as soon as you receive it, with no additional programming required.
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the ECM correctly for your specific truck.
Will this fix my check engine light?
If the check engine light is caused by an internal ECM fault (common codes include P0601, P0606), this part is the correct solution. However, you should always have your vehicle properly diagnosed to confirm the ECM is the source of the problem before ordering.
Is this a difficult installation?
For someone with mechanical experience, the physical installation is straightforward. On most 2007 GM trucks, the ECM is located under the battery in the LH front of the engine bay. Always disconnect the battery before starting work. If you are not comfortable with automotive repair, we recommend professional installation.
How does the warranty work?
This unit is backed by our one-year replacement warranty. If you experience any issues with the module within one year of purchase, please contact our support team for assistance and replacement instructions.
