Restore Your Vehicle’s Brainpower and Performance
Is your 2017 GMC Yukon or other compatible GM vehicle suffering from perplexing issues like stalling, erratic shifting, a persistent check engine light, or a no-start condition? The Engine Control Module (ECM) is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shifts. When it fails, the symptoms can be frustrating and difficult to diagnose. This direct-fit Engine Control Module, part number 12692068, is the definitive solution to restore your vehicle’s factory performance and reliability.
Unlike sourcing a used module from a salvage yard, which would require expensive dealership programming, this ECM arrives at your door pre-programmed to your specific vehicle. We use your Vehicle Identification Number (VIN) to load the latest, most stable GM-certified software, ensuring seamless integration and optimal function. This critical step saves you time, money, and the headache of dealing with incompatible software.
A Technician’s Notebook: The Intermittent Stall Case
I once had a 2017 Sierra 1500 in my bay with an issue that drove the owner crazy: it would randomly stall at traffic lights, but not every time. There were no consistent trouble codes, just a history of U0100 (Lost Communication with ECM). After checking all the power and ground circuits to the ECM and verifying the communication network was physically intact, we suspected the module itself. We swapped in a pre-programmed ECM like this one, and the problem vanished instantly. The original module had an internal hairline fracture on the circuit board that would separate when it got hot, causing the intermittent communication loss. It’s a classic failure mode that a simple code scan doesn’t always pinpoint.
Diagnosing a Faulty 2017 Yukon Engine Control Module
A failing ECM can mimic many other problems, so a proper diagnosis is key. If you or your mechanic have ruled out sensor or wiring issues, the ECM is the likely culprit. This module is the correct component to resolve these issues and get your truck or SUV running smoothly again.
Common Signs of ECM Failure
- ✔ Check Engine Light is illuminated with codes like P0601, P0606, or P062B.
- ✔ Vehicle refuses to start or has difficulty starting.
- ✔ Unexplained drop in fuel economy.
- ✔ Engine stalling, misfiring, or running rough.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Loss of communication with other vehicle modules (U-codes).
A Straightforward Guide to Installation
Replacing the ECM is a manageable job for a DIYer with basic tools or a quick task for any professional technician. The most critical part of the process is the post-installation procedures.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On most trucks and SUVs like the Yukon and Tahoe, the ECM is found in the engine compartment on the driver’s side, near the firewall or fuse box.
- Disconnect Connectors: Carefully release the locking tabs and unplug the wiring harness connectors from the old module. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM and securely plug in the wiring harness connectors.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Relearn Procedures: This is a vital step. If the vehicle does not start, a Vehicle Theft Deterrent System Relearn must be performed using a GM-compliant scan tool with access to Tis2web or Techline Connect. Other procedures like a Crankshaft Position Variation Relearn may also be necessary. This is the responsibility of the installer.

Frequently Asked Questions
How do I provide my VIN for programming?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. The VIN is typically found on your driver’s side dashboard or door jamb sticker.
What is a Vehicle Theft Deterrent Relearn?
This is a security procedure that syncs the new ECM to your vehicle’s ignition key and Body Control Module. It requires a professional scan tool with GM software access (like Techline Connect). Most automotive repair shops can perform this procedure. It is required for the vehicle to start and run after installation.
Will I need to do any other relearns?
Possibly. Depending on your vehicle, you or your mechanic may need to perform additional setup procedures, such as a Crankshaft Position Variation Relearn (Case Relearn) or injector flow rate programming. This is standard practice when replacing an ECM.
Is this a brand new part?
This is a high-quality, inspected, and tested recycled OEM part. It is programmed with the latest GM software for your VIN, ensuring it functions to original factory specifications.
What if I order the wrong part?
Please verify the part number and check the fitment list carefully. Providing your VIN for programming is the best way to ensure compatibility. If you are unsure, contact us before ordering, and our expert team can help you confirm the correct part for your vehicle.
