2007 Suburban 2500 ECM Engine Control Module 19210738 | Programmed

Restore Peak Performance to Your GM Truck or SUV

Is your 2007 Suburban 2500 running rough, stalling unexpectedly, or showing a persistent Check Engine Light? As a technician with over two decades of experience under the hood, I’ve seen these symptoms countless times. More often than not, the culprit is a failing Engine Control Module (ECM)—the central computer that manages everything from fuel mixture and ignition timing to transmission shifts. When the brain of your engine starts to falter, it can cause a cascade of frustrating and potentially damaging problems.

This isn’t just a replacement part; it’s a complete solution. We’re offering a high-quality ECM (Part No. 19210738) that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates flawlessly with all other systems in your vehicle. By flashing it with the latest GM-certified software before it even leaves our facility, we eliminate the need for an expensive trip to the dealership for programming. You get a part that’s ready for installation right out of the box, saving you significant time and money.

Is Your GM Vehicle Showing These Red Flags?

A failing ECM can manifest in various ways. If you’re experiencing any of the following, it’s a strong indicator that your engine’s computer may need replacement. A faulty 2007 Suburban 2500 ECM can be the root cause of many headaches.

• ✔ Check Engine Light is on or flashing
• ✔ Engine cranks but refuses to start
• ✔ Rough or unstable idle
• ✔ Noticeable decrease in fuel economy
• ✔ Hesitation or stumbling during acceleration
• ✔ Failed emissions test
• ✔ Automatic transmission shifting erratically or harshly
• ✔ Common Diagnostic Trouble Codes (DTCs) stored, such as P0601, P0602, P0606, or U0100.

A Straightforward Guide to Installation

Replacing the ECM on many compatible GM trucks and SUVs is a job most DIY enthusiasts can handle in their own driveway. While the exact location can vary slightly by model, the process is generally the same. This guide focuses on the common truck/SUV location.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental power surges.
2. Locate the ECM: On most 2007 GM trucks and SUVs like the Suburban, Silverado, and Tahoe, the ECM is located on the driver’s side, mounted to a bracket underneath the battery tray. You will likely need to remove the battery to gain access.
3. Disconnect Harnesses: Carefully disengage the locking tabs on the electrical connectors and pull them straight out from the module. There are typically two or three large connectors. Avoid pulling on the wires themselves.
4. Remove the Old Module: Unbolt the ECM from its mounting bracket. Keep the hardware, as you will need it to install the new part.
5. Install the New ECM: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware. Reconnect the electrical harnesses, ensuring they click securely into place.
6. Final Steps: Reinstall the battery and connect the negative terminal. Your vehicle is now ready to start. The new ECM will perform a self-learning process over the first 50-100 miles of driving as it fine-tunes parameters.
