Restore Peak Performance to Your GM Vehicle
Are you experiencing frustrating issues like a persistent Check Engine Light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your vehicle’s engine performance. This genuine GM ECM, part number 12676230, is the definitive solution to get your truck, SUV, or performance car back on the road with confidence. We take the guesswork and hassle out of the repair by programming the module to your specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership for programming—it’s ready for installation right out of the box.
Common Symptoms of a Failing ECM & Your Direct Solution
A faulty ECM can cause a wide range of confusing and intermittent problems. If your vehicle is exhibiting any of the following, this module is the solution you need:
- Persistent Check Engine Light: Often with codes like P0601, P0606, or other internal processor faults.
- Engine Performance Issues: Stalling, hesitation, poor acceleration, and reduced fuel economy.
- Erratic Shifting or Transmission Problems: The ECM communicates with the transmission controller, and a fault can cause shifting issues.
- Intermittent or Total No-Start Condition: The engine may crank but refuse to start due to a lack of fuel or spark commands from the ECM.
- Communication Errors with Other Modules: A failing ECM can disrupt the entire vehicle network.
By installing our programmed 2015-2016 Escalade ECM, you are restoring the central command unit of your engine with the latest GM software, ensuring all parameters are set precisely for your vehicle’s configuration.

An Expert’s Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed module. The result is almost always the same: a vehicle that won’t start or runs worse than before. Modern vehicles operate on a complex communication network (CAN bus). The ECM is the conductor of this orchestra. When you provide your VIN, we’re not just loading software; we’re telling the new ECM how to communicate with the transmission, the anti-lock brakes, the instrument cluster, and even the radio. This pre-programming service is the crucial step that transforms a simple part into a true, seamless solution, saving you from days of diagnostic headaches.
Don’t let a faulty computer keep your vehicle sidelined. This programmed 2015-2016 Escalade ECM is the most reliable and efficient way to solve complex electronic issues and restore the performance and dependability you expect from your GM vehicle.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. We handle all the programming for you before shipment. The module arrives ready to be installed. Depending on your vehicle’s security system, you may need to perform a simple key relearn or security relearn procedure, which can typically be done without special tools.
How do I provide you with 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 and validate your VIN, as it is essential for the programming process.
Is this ECM compatible with other part numbers?
Yes, this unit is a direct replacement for several part numbers, including: 12692067, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, and 12669318. Ordering this part ensures you receive a compatible module with the correct software.
My vehicle isn’t an Escalade. Will this still fit?
Absolutely. While we use the programmed 2015-2016 Escalade ECM as a primary example, this part fits a wide range of GM vehicles including the Silverado, Sierra, Tahoe, Suburban, Corvette, Camaro, CTS, and more. Please review the detailed fitment list on this page to confirm compatibility with your specific model and year.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself for a full year from the date of purchase.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your existing ECM (common codes include P0601-P0606), then this part is the correct fix. However, a check engine light can be caused by hundreds of other issues. It is always best to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
