Restore Peak Performance to Your GM Truck or SUV
Is your 2015-2016 GMC Yukon, Sierra, or other compatible GM vehicle suffering from perplexing issues like a persistent check engine light, rough idling, poor fuel economy, or even a no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, the entire vehicle’s performance and reliability are compromised. This isn’t just an inconvenience; it’s a critical component failure that needs immediate attention.
This replacement Engine Control Module, part number 12673195, is the definitive solution to get your vehicle running like new again. We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store, this unit is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). This ensures that all factory settings, security information, and the latest GM software updates are loaded before it ever ships. The result is a streamlined installation process and the restoration of your vehicle’s original performance and efficiency.
We had a 2015 Sierra 1500 come into the shop with a list of bizarre, intermittent symptoms. The owner complained of random stalling at stoplights, occasional hard shifting, and a check engine light that would come and go. We scanned it and found a slew of communication error codes (U-codes) pointing to network issues. After hours of chasing wires and checking grounds, we finally isolated the problem by monitoring network data during a test drive. The ECM was intermittently dropping offline, causing chaos across the vehicle’s computer network. We installed a VIN-programmed module, performed the security relearn, and the truck ran perfectly. It’s a textbook example of how a failing ECM can manifest as more than just simple engine misfires.
Is Your Vehicle Showing Signs of ECM Failure?
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass state emissions inspections
- ✔ Unexplained loss of power and acceleration
The Importance of a VIN-Programmed 2015-2016 Yukon ECM
In modern vehicles, the ECM is not a one-size-fits-all part. It’s integrated with the vehicle’s anti-theft system (immobilizer), transmission controls, and various other modules. Simply swapping a used module from another vehicle will result in a no-start condition and multiple warning lights. Our process eliminates this problem. By providing your VIN at checkout, you receive a 2015-2016 Yukon ECM that is prepared to communicate with your specific vehicle’s components. This service includes loading the latest, most stable software provided by GM, which can often resolve underlying drivability issues that were present even before the original module failed.
This module is a direct replacement for a wide range of GM vehicles and is compatible with the following part numbers: 12692067, 12676230, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, and 12669318. Please verify your part number or provide your VIN to ensure perfect compatibility.
Installation is straightforward for an experienced technician or a skilled DIYer. While the module is programmed for your vehicle, some models may require a simple security relearn procedure or crankshaft position sensor variation relearn after installation. These procedures can typically be done without a high-end scan tool and instructions are widely available.
Frequently Asked Questions
Do I need to have this ECM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready for installation with the latest GM software.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific vehicle. We use it to access the exact factory software, security protocols, and operational parameters for your truck or SUV, ensuring the ECM works perfectly upon installation.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this part will resolve the issue. It’s crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
Is any additional setup required after I install it?
In many cases, it’s a plug-and-play installation. However, some GM vehicles may require a security relearn procedure (often called a key relearn) or a crankshaft position sensor relearn. These are standard procedures that can be performed after the part is installed.
How do I know if this part fits my vehicle?
This module fits a wide range of GM vehicles including the 2015-2016 Yukon, Sierra, Silverado, Tahoe, and Escalade. The best way to confirm is to match the part number on your old module to 12673195 or one of the other compatible numbers listed. Providing your VIN is the most certain way to guarantee a match.
