Restore Peak Performance to Your GM 3.6L Vehicle
Is your 2008-2009 Cadillac CTS, Acadia, or Enclave suffering from perplexing engine issues? A faulty Engine Control Module (ECM) is often the culprit behind poor fuel economy, erratic performance, and a persistent check engine light. The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, the entire system can be compromised. This replacement Engine Control Module, part number 19300016, is the definitive solution to get your vehicle running like new again.
From the Diagnostic Bay
We had a 2009 GMC Acadia come in with a complaint of intermittent stalling and a check engine light that multiple shops couldn’t solve. They had replaced sensors and spark plugs, but the problem persisted. After hooking up our diagnostic tools, we noticed erratic data from the ECM. Instead of a costly and time-consuming trip to the dealership, the owner opted for one of our pre-programmed modules. We provided the vehicle’s VIN, installed the new unit in under 30 minutes, and the Acadia ran perfectly. The VIN-specific programming ensured all the vehicle’s unique systems communicated correctly, solving a problem that had plagued the owner for months.
Symptoms of a Failing 2008-2009 CTS Engine Control Module
A failing ECM can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer may be at fault:
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling or misfiring unexpectedly
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Rough or inconsistent idling
- ✔ Poor acceleration and overall loss of power
- ✔ Automatic transmission shifting issues
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the ECM with the exact software and calibrations for your specific make, model, engine, and options. This ensures perfect compatibility and function, making the installation truly plug-and-play.
Is this module difficult to install?
No, the physical installation is straightforward. On the CTS and STS, it’s located in the right-hand engine compartment. On the Acadia, Traverse, Outlook, and Enclave, it’s behind the fan shroud. Since it comes pre-programmed, no further computer work is needed after installation. However, we always recommend disconnecting the battery before starting work.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, this part will resolve the issue. We recommend having your vehicle scanned for diagnostic trouble codes (DTCs) to confirm the ECM is the problem before ordering.

No. Our programming service means this module arrives ready for installation. You will not need to take your vehicle to a dealership or mechanic for additional flashing or programming, saving you time and money.
