Restore Peak Performance to Your GM Vehicle
Is your 2010-2011 Cadillac CTS, Buick Enclave, or Chevy Traverse suffering from perplexing engine issues? An illuminated Check Engine Light, rough idling, stalling, or a sudden drop in fuel efficiency are all classic signs of a failing Engine Control Module (ECM). The ECM is the central computer, the brain of your engine’s operation, managing everything from fuel injection and ignition timing to emissions control. When it falters, the entire vehicle’s performance and reliability are compromised. This isn’t just an inconvenience; it can lead to more significant engine problems if left unaddressed.
We offer a direct, reliable solution: a replacement Engine Control Module, part number 12617230, professionally programmed specifically for your vehicle. Forget the hassle and high cost of dealership programming. We use the latest GM software updates and your vehicle’s unique Vehicle Identification Number (VIN) to ensure this module is a perfect match, ready for installation right out of the box for most models. This process restores the precise factory settings your engine needs to run smoothly and efficiently.
From the Diagnostic Bay
We recently had a 2011 GMC Acadia come in that had its owner at his wit’s end. He had already replaced the mass airflow sensor, all four oxygen sensors, and even the throttle body based on a series of persistent, yet inconsistent, trouble codes. The engine would run fine for a day, then suddenly start stumbling and losing power. After hooking up our advanced scanner and monitoring live data, we noticed the fuel trim and ignition timing values were fluctuating wildly, far beyond normal parameters. The sensors weren’t faulty; they were getting incorrect commands from a failing ECM. We installed a VIN-programmed module, and the Acadia immediately ran like new. It’s a classic case where chasing symptoms instead of the root cause can be costly and frustrating.
Common Symptoms of a Failing 2010-2011 CTS ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Engine stalling or shutting off while driving
- ✔ Rough or erratic idling
- ✔ Noticeable decrease in fuel economy
- ✔ Engine misfires or hesitation during acceleration
- ✔ Difficulty starting the engine or a no-start condition
- ✔ Inconsistent or harsh automatic transmission shifting
- ✔ Failure to pass state emissions testing
A Complete, Programmed Solution
This isn’t just a part; it’s a complete service designed to get you back on the road quickly. The key to a successful ECM replacement is the programming. An unprogrammed module will not allow your vehicle to start or run correctly. By providing us with your VIN during checkout, you authorize us to flash the module with the correct software for your specific make, model, year, and factory options. This ensures all components communicate correctly, from the engine and transmission to the anti-theft system.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle all the programming for you before shipment. By providing your vehicle’s VIN, we will flash the module with the latest GM software specific to your car, saving you a trip to the dealership and their associated programming fees.
Is this installation plug-and-play?
For most listed vehicles (like the CTS, Acadia, Enclave, Traverse), yes. Once you receive the programmed module, you simply disconnect the battery, swap the part, and reconnect the battery. However, for the 2010-2011 Camaro and LaCrosse, we need to transfer immobilizer data from your old unit to make the new one plug-and-play. We will coordinate this with you after your order is placed.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What happens if I forget to provide my VIN?
Your order cannot be processed or shipped without a valid VIN. We will place your order on hold and contact you via email or phone to retrieve the necessary information. Providing the VIN during checkout is the fastest way to get your part.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, it’s always recommended to have a professional diagnosis performed to rule out other potential causes like wiring or sensor faults.
