Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) is essential for us to load the correct, vehicle-specific software and calibrations from GM. This step ensures the ECM communicates perfectly with your Suburban’s engine, transmission, and security systems, making the installation process as simple as possible.
Is this part difficult to install?
The physical installation is straightforward for a DIYer with basic tools, as it’s a direct-fit part. Because we pre-program the module, you avoid complex dealer-level programming. However, some GM vehicles may require a simple security ‘relearn’ procedure after installation, which can often be done without special tools. We recommend consulting a service manual for your specific vehicle.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., codes like P0606), then this replacement module is the correct fix. It is crucial to properly diagnose the issue first to ensure the fault isn’t with a sensor or wiring, as the ECM can only function with correct information from the vehicle’s systems.
How do I know for sure that my ECM is the problem?
Common signs of a failing ECM include a no-start condition where the engine still cranks, multiple unrelated error codes, and communication issues with diagnostic scan tools. If you’ve ruled out sensor, wiring, and power supply issues, the ECM is the most likely culprit. A professional diagnosis is always recommended.
What is the warranty on this module?
This unit is backed by our one-year replacement warranty. This provides coverage against defects and gives you assurance in the quality and reliability of your purchase.
Is this the right part for my other GM truck or car?
Yes, this 2015-2016 Suburban 1500 ECM 12663391 is also compatible with a wide range of other GM vehicles, including the Silverado 1500, Sierra 1500, Tahoe, Yukon, Escalade, Corvette, and more.
