Restore Your Truck’s Brain and Get Back on the Road
Is your 2014-2016 Silverado 1500 running rough, throwing confusing check engine codes, or refusing to start? The Engine Control Module (ECM) is the central computer of your vehicle, managing everything from fuel injection and ignition timing to transmission shifts. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This direct-fit Engine Control Module, part number 12672537, is the definitive solution to get your truck operating at peak efficiency again.
Unlike a generic module from a parts store or a salvage yard, this ECM arrives at your door specifically programmed for your truck. We use the Vehicle Identification Number (VIN) you provide to flash the module with the latest, most stable GM-approved software. This critical step ensures seamless communication with all other modules in your vehicle, eliminating compatibility issues and saving you a costly trip to the dealership for programming.
From the Diagnostic Bay
We had a 2015 Sierra 1500 in the shop that was a real head-scratcher. The owner complained of random stalling at stoplights and a transmission that seemed to have a mind of its own, occasionally getting stuck in gear. We checked all the usual suspects—sensors, wiring, fluid levels—and found nothing. Diagnostic scans showed intermittent communication loss with the ECM. Instead of spending hours trying to isolate a potential internal fault, we opted for a known-good, pre-programmed ECM. After a straightforward installation and a quick security relearn procedure, the truck ran perfectly. All the ghost-like issues vanished. It’s a testament to how a failing ECM can mimic a dozen other problems, and how the right part can be a simple, effective fix.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various codes
- ✔ Engine misfires, stumbles, or stalls unexpectedly
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start or intermittent starting issues
- ✔ Inability for diagnostic scan tools to communicate with the module
- ✔ Performance issues like poor acceleration or hesitation

Frequently Asked Questions
Do I absolutely have to provide my VIN?
Yes. Providing your VIN is mandatory. We cannot ship the module without it. The VIN is required to load the correct, vehicle-specific GM software and calibrations, ensuring the ECM works perfectly with your truck’s engine, transmission, and options.
Is this part ready to install out of the box?
The module is pre-programmed and ready for physical installation. However, after installation, you will likely need to perform a security relearn procedure. This syncs the new ECM with your vehicle’s anti-theft system and keys. Instructions for this procedure are widely available and typically do not require special tools.
My original part number isn’t 12672537, but it’s on the compatible list. Will this work?
Yes. Manufacturers often consolidate multiple part numbers into a single, updated service part. If your original part number is on our cross-reference list, this module is the correct, updated replacement for your vehicle.
Will this ECM fix my vehicle’s problem?
This module will resolve any issue directly caused by a faulty ECM. It is crucial to have your vehicle properly diagnosed by a qualified mechanic to confirm the ECM is the source of the problem before ordering.
What is the location of the ECM on a 2014-2016 Silverado?
On most 2014-2016 Silverado and Sierra 1500 models, the Electronic Control Module (ECM) is located in the engine compartment on the driver’s side, near the front.
