Is your 2007 GMC Yukon XL 1500 running rough, stalling, or refusing to start? Are you battling a persistent Check Engine Light with confusing diagnostic codes? The Engine Control Module (ECM) is the brain of your vehicle’s engine, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. This direct-replacement ECM, part number 12589297, is the definitive solution to restore your truck’s performance, reliability, and efficiency.
Unlike a standard replacement part from a local store, this module arrives at your door specifically programmed for your vehicle. We use your Yukon’s unique Vehicle Identification Number (VIN) to load the latest, most stable GM factory software. This critical step ensures seamless communication with all other vehicle systems, eliminates the need for an expensive trip to the dealership for programming, and can even resolve underlying issues that were present in the original factory software.
From the Diagnostic Bay
I once had a 2007 Sierra with the 5.3L come in that was driving the owner crazy. The truck would randomly misfire, the transmission would shift hard, and he had already replaced three different sensors based on generic codes. A deep dive with the scan tool showed intermittent communication loss with the ECM. We swapped in a VIN-programmed module, performed the security relearn, and the truck ran perfectly. The original ECM had internal faults that were corrupting data, making the sensors appear faulty. It’s a classic case where treating the root cause—the failing computer—is the only real fix.
Is Your Yukon XL Showing Signs of a Failing ECM?
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
- ✔ Communication errors when trying to use an OBD-II scan tool.
- ✔ Multiple, unrelated diagnostic trouble codes (DTCs) being stored.

Frequently Asked Questions
What do I need to do after I install this ECM?
After installation, you will need to perform a security relearn procedure, often called the Passlock or Passkey relearn. This procedure syncs the new ECM with your vehicle’s anti-theft system and can typically be done without special tools in about 30 minutes. Instructions are readily available online or in service manuals. In some cases, a Crankshaft Position Sensor (CASE) relearn may be needed, which requires a capable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information, as the programming is specific to your truck.
Is this ECM truly plug-and-play?
It is as close as it gets. The module arrives with the correct software for your VIN, which is the most complex part of the job. The only additional step required by you is the security relearn procedure, which is a necessary step for any ECM replacement on these vehicles.
Will this fix my specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, then this part is the solution. Common symptoms include multiple unrelated error codes, no-start conditions, and erratic engine behavior that isn’t caused by other sensors or mechanical parts.
Where is the ECM located on my 2007 Yukon XL?
On most 2007 GM trucks and SUVs like the Yukon XL, Tahoe, and Silverado, the ECM is located in the engine bay on the driver’s side, mounted in a bracket under the battery tray.
