Restore Peak Performance to Your 2007 Chevrolet Avalanche
Is your 2007 Avalanche 1500 suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your truck’s engine performance, fuel delivery, and emissions. A faulty ECM can make your reliable truck feel unpredictable and unsafe. This direct-fit Engine Control Module, part number 19210738, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We once had a 2007 Silverado (which uses the same ECM) come into the shop with a laundry list of problems. The owner had already replaced the MAF sensor, O2 sensors, and even the throttle body based on various codes, but the truck still ran poorly and would randomly go into limp mode. After confirming power and ground to the ECM were good, we connected our scope and found the driver circuit for an injector was failing intermittently inside the module itself. A new, properly programmed ECM was the only fix. This highlights how a single failing module can mimic multiple other component failures, costing you time and money on parts you don’t need.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine misfires, stumbles, or stalls unexpectedly.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Poor acceleration and overall sluggish performance.
- ✔ Transmission shifting issues or harsh shifts.
- ✔ Communication errors with diagnostic scan tools.
The Plug-and-Play Solution: A Programmed 2007 Avalanche 1500 ECM
Replacing an ECM isn’t just about swapping the hardware. The module must be correctly programmed with your vehicle’s specific Vehicle Identification Number (VIN) and the latest factory software to function. Our service eliminates the most difficult part of the job. We take care of the programming for you before we ship. Simply provide us with your VIN during checkout, and you’ll receive a module that is ready for installation, loaded with the newest updates from GM. This process ensures perfect compatibility and optimal performance, saving you from expensive programming fees and the hassle of a trip to the dealership.
This module is a direct replacement for several part numbers, including 12589297, 12597121, 12603892, and 19210738. It is also compatible with a wide range of other 2007 GM trucks and SUVs, such as the Escalade, Sierra, Silverado, Suburban, Tahoe, and Yukon, ensuring a precise fit and function for your specific application.
Installation is straightforward. On most compatible trucks and SUVs, the ECM is located on the driver’s side, under the battery tray. After disconnecting the battery, you can unbolt the old module, disconnect the wiring harnesses, and install the new one in its place. Once installed, you may need to perform a simple security relearn procedure, which can typically be done without any special tools. This will sync the new ECM with your vehicle’s anti-theft system.
Frequently Asked Questions
Do I need to get this module programmed?
No. This is the primary benefit of our service. We program the module with your vehicle’s VIN and the latest GM software before it ships. It arrives ready to be installed.
Where is the ECM located on my 2007 Avalanche?
On the 2007 Avalanche 1500, the Engine Control Module is typically located in the engine bay on the driver’s side, mounted underneath the battery tray.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for programming.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this replacement part will resolve the issue. It’s crucial to ensure the problem has been correctly diagnosed before ordering.
Is any other procedure required after installation?
In many cases, you may need to perform a security relearn procedure (also known as a VATS relearn) to sync the new ECM with your vehicle’s anti-theft system. This procedure can usually be done at home and does not require special tools.
