Restore Peak Performance to Your Cadillac Escalade ESV
As a technician with over two decades of experience under the hood, I’ve seen firsthand the frustration a failing Engine Control Module (ECM) can cause. Your 2015-2016 Cadillac Escalade ESV is a sophisticated machine, and its ECM is the brain behind the operation. When it falters, you can experience everything from a nerve-wracking no-start condition to poor fuel economy and a persistent Check Engine light. This isn’t just an inconvenience; it’s a compromise on the reliability and performance you expect from a premium vehicle.
This is a direct-fit replacement Engine Control Module, part number 12676230, meticulously prepared for your vehicle. The most significant benefit we offer is our professional programming service. Before this module ships, we flash it with the latest official GM software updates, using the VIN you provide at checkout. This ensures it communicates flawlessly with your Escalade’s specific systems, restoring factory performance and efficiency without a costly trip to the dealership for programming.
A Technician’s Notebook
I recently worked on a 2015 Escalade ESV with a classic intermittent problem. The owner reported that some mornings it would crank but not start, yet other times it fired right up. There were no consistent trouble codes, just a generic U0100 ‘Lost Communication with ECM’ code that would pop up occasionally. After verifying power and ground at the ECM connectors were solid, we suspected an internal failure. Instead of a gamble at the dealer, the owner opted for one of our pre-programmed modules. The installation took less than 30 minutes, and the problem was solved instantly. The VIN-specific programming made it a true plug-and-play fix, saving the customer hundreds in diagnostic and programming fees.
Is Your Escalade Exhibiting These ECM Failure Signs?
A faulty ECM can manifest in various ways. If you’re experiencing any of the following, a failing module could be the culprit. Look out for these common indicators:
- ✔ Vehicle will not start or has intermittent starting issues.
- ✔ The Check Engine Light is illuminated on your dash.
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0606, or P060A.
- ✔ Communication error codes like U0100, indicating the ECM isn’t talking to other modules.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough idling, engine stalling, or misfires.
- ✔ Problems with automatic transmission shifting.
A Straightforward Guide to Installation
Replacing the ECM on your Escalade ESV is a manageable job for a confident DIYer. Our pre-programmed module eliminates the most complex step. Follow this general guide for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow the system to fully discharge.
- Locate the ECM: On the 2015-2016 Escalade ESV, the Engine Control Module is typically found in the LH (driver’s side) front of the engine compartment.
- Disconnect the Old Module: Carefully release the locking tabs on the electrical connectors and pull them straight out. Avoid wiggling them side-to-side. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place. Firmly reconnect the electrical connectors, ensuring they click and lock securely.
- Final Steps: Reconnect the negative battery terminal. The vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Start the engine and verify the Check Engine light is off and the vehicle runs smoothly.

No. This module arrives at your door fully programmed with the latest GM software for your specific vehicle. All we need is your VIN during checkout. This makes the installation process simple and saves you a trip to the dealer.
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function correctly.
This ECM will resolve any issues directly caused by a faulty module, including internal processor faults (like code P0606) and communication errors. However, if your Check Engine Light is on due to other failing parts (e.g., a bad oxygen sensor or catalytic converter), those issues will still need to be addressed separately.
The Engine Control Module is located in the front of the engine compartment on the driver’s side (LH side).
This module is a direct replacement for a range of part numbers, including 12692067, 12656993, 12662034, and others listed in the description. As long as your vehicle is listed in our compatibility chart, this module will work once programmed to your VIN.
