Restore Peak Performance to Your GMC Yukon XL
Is your 2017 Yukon XL 1500 suffering from frustrating and unpredictable issues like stalling, rough idling, or a persistent check engine light that just won’t go away? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. Don’t let a faulty ECM compromise the reliability and safety of your family’s transportation. This direct-replacement ECM is the definitive solution, arriving at your door pre-programmed to your vehicle’s specific VIN with the latest GM software updates.
Common Symptoms & Your Solution
A failing engine computer can cause a cascade of problems that can be difficult to diagnose. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light (CEL): Particularly for internal module failure codes like P0601, P0606, or P062B.
- No-Start or Hard-Start Conditions: The engine cranks but refuses to start, or starts only after multiple attempts.
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.
- Communication Errors: Your scanner may show a U0100 (Lost Communication With ECM/PCM) code.
- Erratic Shifting or Stalling: The vehicle may stall unexpectedly at stops or shift gears harshly.
By installing our 2017 Yukon XL 1500 Programmed ECM, you are directly addressing the root cause of these issues and restoring the precise, factory-intended operation of your engine and transmission.

Expert Insight: The Digital Heartbeat of Your Truck
Your Yukon’s ECM is more than just a box; it’s the nerve center of a complex digital network. It constantly processes thousands of data points from sensors all over the vehicle to manage everything from fuel injection and spark timing to transmission shifts. That’s why simply swapping in a used module from a junkyard often fails—it’s not programmed for your vehicle’s unique options and security protocols. Our process ensures this new module is a perfect digital match, restoring the factory ‘handshake’ between all your vehicle’s components for a lasting, reliable repair.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians use this VIN to load the latest, correct software from GM directly onto the module before it ships. This ensures it’s ready for your specific vehicle configuration.
What is a “theft relearn” and will I need to do it?
The Vehicle Anti-Theft System (VATS) links your key, ignition, and ECM. Sometimes, after installing a new ECM, the system needs to be reset to recognize the new component. This is called a theft relearn. If your vehicle does not start after installation, this procedure will be required. It must be performed by a qualified technician with access to GM’s official programming software like Tis2web or Techline Connect. This is the responsibility of the installer.
Is this a simple plug-and-play installation?
For many vehicles, it is. You disconnect the battery, swap the module, and reconnect the battery. However, as noted, some vehicles will require a security relearn. Additionally, other procedures like a crankshaft variation relearn may be necessary to clear all trouble codes and ensure optimal performance. These are standard procedures for this type of repair.
How can I be sure my ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a professional mechanic is always the best course of action. Common diagnostic trouble codes (DTCs) pointing to ECM failure include P0601, P0606, and various communication codes (U-codes). If your mechanic has condemned the ECM, this 2017 Yukon XL 1500 Programmed ECM is the ideal replacement.
Does this part fit other GM vehicles?
Yes, this ECM is compatible with a wide range of GM trucks and SUVs from a similar time frame, including the Cadillac Escalade, Chevy Tahoe, Suburban, and Silverado 1500, as well as the GMC Sierra 1500. Please check the fitment list and part numbers provided to confirm it matches your specific vehicle.
