Restore Peak Performance to Your GM Vehicle
Is your 2016 Cadillac CT6, Chevrolet Cruze, or Malibu suffering from perplexing electrical issues, a persistent check engine light, or poor engine performance? The Engine Control Module (ECM), the master computer of your vehicle, is often the culprit. When it fails, it can cause a cascade of problems that are frustrating and difficult to diagnose. This genuine GM ECM, part number 12672502, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and additional cost out of the repair by programming the module specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership for programming, no special tools required, and a much simpler installation process for you or your mechanic.
I remember a 2016 Malibu that came in with a no-start condition that had stumped two other shops. The owner had replaced the battery, starter, and even the fuel pump. We scanned it and found a dozen communication codes (U-codes) across various modules. Instead of chasing ghosts, we went straight to the source: the ECM. We checked the power and ground feeds to the module, which were perfect. However, the ECM wasn’t broadcasting on the CAN bus network. A quick swap with a known-good, programmed ECM like this one, and the car fired up on the first try. It’s a powerful reminder that the ECM is the conductor of the orchestra; if it goes silent, so does everything else.
Is Your ECM Failing? Common Symptoms
- ✔ Check Engine Light: An illuminated Check Engine Light (CEL) is the most common sign, often with codes related to sensor circuits (P0xxx), internal module failure, or communication errors (Uxxxx).
- ✔ No-Start or Hard Starting: The engine may crank but refuse to start, or take an unusually long time to fire up, either hot or cold.
- ✔ Poor Engine Performance: You might experience stalling, rough idling, hesitation during acceleration, or a noticeable loss of power and fuel economy.
- ✔ Erratic Transmission Shifting: The ECM communicates directly with the transmission controller. A faulty ECM can lead to harsh shifts, getting stuck in gear, or incorrect shift timing.
- ✔ Intermittent Electrical Issues: Seemingly unrelated problems, like cooling fans not turning on or inaccurate gauge readings, can sometimes be traced back to a failing ECM.
The Advantage of a Pre-Programmed 2016 CT6 ECM
Modern vehicles require a complex ‘handshake’ between modules for security and proper function. Simply installing a blank ECM will not work; the vehicle will not start due to the anti-theft system. Our process eliminates this barrier. By providing your VIN, you receive a 2016 CT6 ECM that is loaded with the latest GM-certified software and calibrated specifically for your vehicle’s original configuration. This ensures all systems, from the engine and transmission to the emissions equipment, function exactly as the manufacturer intended. It’s a true plug-and-play repair that saves you hundreds of dollars in dealership programming fees.

Frequently Asked Questions
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your vehicle. The order will be held until we receive the correct VIN from you.
Is any additional programming required after installation?
In most cases, no. Our programming covers the engine and transmission software. However, some vehicles may require a simple ‘relearn’ procedure for the crankshaft position sensor or security system, which can often be done without special tools. Instructions for common relearn procedures can be found online or in a service manual.
