Is Your Tahoe Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than when your reliable family SUV, the 2015-2016 Chevrolet Tahoe, starts acting up. A flickering check engine light, unexplained stalling, or poor fuel economy can turn any drive into a stressful experience. These are often signs that the brain of your vehicle—the Engine Control Module (ECM)—is failing. This isn’t just an inconvenience; it’s a matter of reliability and safety. This direct-fit, professionally programmed ECM is the definitive solution to restore your Tahoe’s performance and give you back the peace of mind you deserve.
Common Symptoms of a Failing ECM & Your Solution
A faulty ECM can cause a cascade of confusing issues. If you’re experiencing any of the following, a replacement is likely the answer:
- Persistent Check Engine Light: Especially with codes like P0601, P0606, or other internal processor errors.
- Engine Performance Problems: Rough idling, hesitation during acceleration, stalling, or a complete no-start condition.
- Reduced Fuel Economy: The ECM controls the fuel mixture, and a failing unit can cause your truck to consume more gas than usual.
- Erratic Transmission Shifting: The ECM communicates with the transmission controller, and faults can lead to harsh or incorrect shifts.

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. This ECM is a complete plug-and-play solution. We flash it with your vehicle’s VIN and the latest GM software before it ships, so it’s ready for installation as soon as you receive it.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module to match your vehicle’s exact specifications before shipping.
Will this fix my specific check engine light codes?
This ECM is the correct fix for module-specific codes, such as P0601 (Internal Control Module Memory Check Sum Error) and P0606 (ECM/PCM Processor Fault). While it can resolve many other performance issues, we always recommend having a qualified mechanic diagnose your vehicle to confirm the ECM is the root cause of the problem.
What if my truck has an anti-theft system?
In some cases, a simple security relearn procedure may be required after installation. This procedure can typically be done by yourself in about 15 minutes without any special tools and we can provide instructions if needed. It syncs the new ECM with your vehicle’s existing anti-theft system.
Is this compatible with other GM trucks and SUVs?
Yes, this ECM is compatible with a wide range of GM vehicles, including the Silverado 1500, Sierra 1500, Yukon, Escalade, and Suburban from similar model years. Please check the detailed fitment list on this page to confirm compatibility with your specific model.
