Restore Peak Performance to Your GM Truck or Car

Is your 2012-2016 Sierra 3500 Pickup running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These are classic signs that the engine’s central computer—the Engine Control Module (ECM)—is failing. This critical component manages everything from fuel injection and ignition timing to emissions controls. When it falters, your vehicle’s reliability and performance suffer. This isn’t just an inconvenience; it can be a significant issue, especially for a workhorse like the Sierra 3500. This replacement ECM, part number 12692200, is the definitive solution to get your vehicle running like new again.

We take the guesswork and high costs out of the repair process. Unlike a generic module that requires a trip to the dealer for expensive programming, this unit arrives at your door fully programmed for your specific vehicle. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures perfect communication between the ECM and all other systems in your vehicle, restoring factory performance and efficiency right out of the box.

From the Diagnostic Bay: A Sierra That Wouldn’t Shift Right

A customer brought in a 2014 Sierra 2500 with the 6.0L V8, complaining of harsh shifting and a check engine light. The codes were all over the place—a U0100 for lost communication with the ECM, and a few intermittent transmission codes. The transmission shop had already cleared the transmission, but the problem persisted. After checking the network wiring, I focused on the ECM. On the surface, it seemed fine, but under load, the data stream would drop out for milliseconds. That was enough to confuse the Transmission Control Module (TCM). We installed a pre-programmed ECM, performed the security relearn, and the truck drove perfectly. It wasn’t a transmission problem at all; it was a failing ECM causing communication breakdowns. This is a scenario I’ve seen dozens of times on these GM HD trucks.

Is Your Vehicle Showing These Symptoms?

  • ✔ Persistent Check Engine Light (CEL) that won’t clear.
  • ✔ Engine stalling, stumbling, or hesitating during acceleration.
  • ✔ Noticeable decrease in fuel economy.
  • ✔ No-start condition where the engine cranks but won’t fire up.
  • ✔ Communication error codes, such as U0100, on a diagnostic scan.
  • ✔ Specific ECM failure codes like P0601, P0606, or P062F.
  • ✔ Failure to pass state emissions testing.

A Straightforward Guide to Your 2012-2016 Sierra 3500 ECM Installation

Replacing the ECM on your Sierra 3500 is a manageable job for a confident DIYer. Since this module comes pre-programmed, you’ll avoid the most complicated step. Follow these general steps for a successful installation.

  1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent any accidental power surges.
  2. Locate the ECM: On the 2012-2016 Sierra/Silverado HD trucks, the ECM is typically located in the engine bay on the driver’s side, near the firewall or inner fender.
  3. Disconnect Connectors: Carefully release the locking tabs on the large wiring harness connectors and pull them straight out from the module. Do not force them. Inspect the pins for any corrosion or damage.
  4. Remove the Old Module: Unbolt the old ECM from its mounting bracket. There are usually a few bolts holding it in place.
  5. Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it. Reconnect the wiring harnesses, making sure they click securely into place.
  6. Reconnect Battery: Reattach the negative battery terminal.
  7. Perform Security Relearn: You will need to perform a security relearn procedure (often called a Passlock or anti-theft relearn) so the vehicle recognizes the new ECM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. Your vehicle’s service manual will have the exact procedure.
  8. Start and Verify: Start the engine and check for a smooth idle and ensure the Check Engine Light is off. Take the vehicle for a short test drive.

Frequently Asked Questions

How does the VIN programming work?

After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and load the correct, most current software for your specific vehicle configuration onto the ECM before it ships.

Do I need any special tools for installation?

For the physical swap, you will only need basic hand tools like a socket set. For the required security relearn procedure, you do not need a scan tool; it can be done with the vehicle’s ignition key by following a simple timed sequence.

Is this a used part?

This is a high-quality, tested, and verified recycled OEM part. Each module is inspected and guaranteed to function correctly. By using a genuine OEM part, you ensure perfect fitment and electronic compatibility.

Will this fix my ‘No Communication’ code (U0100)?

In many cases, a faulty ECM is the root cause of a U0100 code. While you should always verify the wiring and connectors first, replacing a bad ECM is a very common fix for this issue.

What is your warranty policy?

We stand behind our parts with a comprehensive warranty. Please see the warranty tab on this page for full details and peace of mind with your purchase.

How quickly will I get my part?

Once we receive your VIN, programming is typically completed within one business day. The module is then shipped out to you via your selected shipping method. We strive to get your vehicle back on the road as quickly as possible.
