Restore Peak Performance to Your GM Vehicle
Is your 2009 Saturn Outlook, GMC Acadia, or Cadillac CTS running rough, stalling unexpectedly, or displaying a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance, fuel economy, and emissions. A faulty ECM can lead to a cascade of frustrating issues, leaving you with an unreliable and inefficient vehicle. This direct-fit ECM, part number 19300016, is the definitive solution to restore your vehicle’s factory performance and reliability.
The Brain of Your Engine, Delivered Ready for Installation
The ECM is arguably one of the most critical components in your vehicle. It processes data from dozens of sensors to precisely control fuel injection, ignition timing, and transmission shifting. When it fails, the entire system is compromised. Our service takes the guesswork and high cost out of the repair. We provide a fully functional ECM that is professionally programmed with the latest GM software updates specifically for your vehicle using the VIN you provide. This means no expensive trips to the dealership for programming—it arrives at your door ready for a straightforward installation.
From the Diagnostic Bay
We had a 2009 GMC Acadia come into the shop with a complaint of intermittent stalling and a P0606 (ECM Processor Fault) code. The owner had already replaced the throttle body and a couple of sensors with no success. After confirming power and ground to the module were solid, we knew the internal processor was the culprit. Instead of a costly dealer replacement, we sourced a pre-programmed module like this one. After installation and performing a quick security relearn procedure (which took about 15 minutes), the Acadia started right up and ran perfectly. The customer saved hundreds of dollars and avoided a lengthy wait at the dealership. It’s a prime example of how a pre-programmed module is the smartest fix for these common failures.
Why Choose Our Pre-Programmed 2009 Outlook Engine Control Module?
This isn’t just a replacement part; it’s a complete solution. By programming the module to your vehicle’s specific VIN, we ensure that all factory settings, anti-theft systems, and component communications are correctly configured. This module is a direct replacement for multiple part numbers, including 12623325, 12628387, 12605672, and 12630594, ensuring wide compatibility across the GM family of vehicles from 2008-2009.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on with codes related to the ECM (e.g., P0601, P0606).
- ✔ Engine stalling or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel economy.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Poor engine performance, hesitation, or rough idling.
- ✔ Automatic transmission shifting erratically.
- ✔ Communication issues with diagnostic scan tools.
If you’re experiencing any of these issues, a failing ECM is a highly likely cause. Replacing it with our pre-programmed 2009 Outlook Engine Control Module is the most efficient way to get your vehicle back on the road and running as it should.
Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to be installed. In some cases, a simple key relearn or security relearn procedure may be necessary, which can typically be done without special tools.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to ensure correct programming.
Is this compatible with my 2008 Cadillac STS?
Yes, this ECM is compatible with the 2008 and 2009 Cadillac STS with the 3.6L engine, as well as several other GM models like the Acadia, Traverse, Enclave, and CTS. Please check the detailed fitment list to confirm for your specific vehicle.
What tools are required for installation?
Installation typically requires basic hand tools like a socket set and ratchet to disconnect the battery and remove the module’s mounting bolts and electrical connectors. The module is usually located behind the fan shroud or in the engine compartment.
What if my original part number is not 19300016?
This module is a direct replacement for several part numbers, including 12623325, 12628387, 12605672, and 12630594. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN.
