Restore Your Truck’s Brain and Bring Back Peak Performance
Is your Yukon XL running rough, throwing confusing check engine codes, or refusing to start reliably? The Engine Control Module (ECM) is the central computer of your vehicle, and when it fails, it can cause a cascade of frustrating and unpredictable problems. Don’t let a faulty module keep you off the road. This genuine OEM Engine Control Module, part number 12617568, is the definitive solution to restore the smooth, powerful, and dependable performance you expect from your truck. We take the guesswork out of the repair by professionally programming this unit to your specific Vehicle Identification Number (VIN) using the latest GM software updates. This ensures seamless communication between all your vehicle’s systems, just like it did from the factory.
Warning Signs and How to Overcome Them
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 needs attention. Replacing it with our pre-programmed unit is the most direct path to a lasting solution.
- ✔ Persistent Check Engine Light: Especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0606, or U-series codes.
- ✔ Engine Performance Issues: Unexplained stalling, rough idling, hesitation during acceleration, or a noticeable drop in fuel economy.
- ✔ Starting Problems: The engine cranks but won’t start, or it starts intermittently.
- ✔ Transmission Woes: Harsh or erratic shifting, as the ECM plays a crucial role in transmission control.
- ✔ No Communication: Your mechanic’s scan tool cannot communicate with the module.
Guided Installation to Restore Peace of Mind
You don’t need to be a master mechanic to complete this job. With our pre-programmed module, the most complex part is already done. Follow these simple steps to get your Yukon back in top shape.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning any electrical work.
- Locate the Module: On your Yukon XL, the ECM is typically found under the hood, on the driver’s side, underneath the battery tray.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the old module from its mounting bracket.
- Install the New ECM: Mount your new, pre-programmed module in the same location. Securely reconnect the electrical harnesses, ensuring they click into place.
- Power Up: Reconnect the negative battery terminal. In many cases, a security relearn procedure may be required, which typically involves cycling the key. Instructions are readily available online or in your owner’s manual.

Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the process of loading your vehicle’s unique software and settings onto the ECM. This includes information about your engine, transmission, tire size, and factory options. It’s essential for ensuring all components communicate and function correctly, preventing performance issues and warning lights.
Is this module truly plug-and-play?
Because we program it with your VIN, it is as close to plug-and-play as possible. However, many GM vehicles of this era require a simple security relearn procedure (often called a ‘key cycle relearn’) to sync the new ECM with the anti-theft system. This can typically be done in your driveway without any special tools.
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 program or ship your module until we receive this information, so please provide it promptly to avoid delays.
What if my old part number isn’t an exact match?
This module replaces several part numbers, including 12612384 and 12622141. As long as your vehicle’s year, make, model, and engine are on the compatibility list, this module will function correctly once programmed to your VIN.
Will this fix my specific problem?
This part is a direct solution for a failed ECM. If your vehicle has been properly diagnosed with a faulty engine computer, this pre-programmed unit will resolve the associated symptoms, such as specific error codes, no-start conditions, and erratic engine behavior.
