Is your 2008-2010 Saturn VUE suffering from perplexing issues like stalling, poor fuel economy, or a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving you with an unreliable and inefficient vehicle. This replacement ECM, part number 12602044, is the definitive solution to restore your vehicle’s original performance and reliability.
From the Diagnostic Bay
We had a 2009 Saturn VUE come into the shop with an intermittent no-start condition that had stumped two other mechanics. The battery, alternator, and starter all checked out perfectly. After hours of tracing wires, we noticed that the fuel pump wasn’t always priming on key-on. A scan tool showed no communication with the ECM during these no-start events. We swapped in a known-good, programmed ECM, and the VUE fired up instantly every single time. It wasn’t a mechanical failure, but a digital one—the original ECM’s internal processor was failing intermittently, a common issue as these modules age.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive with the latest GM software, ready for installation.
What is a VIN-specific flash?
Flashing the module with your Vehicle Identification Number (VIN) ensures that the computer’s software is perfectly matched to your car’s specific options, engine, transmission, and emissions equipment, just as it was from the factory.
Is any special procedure needed after installation?
In many cases, you may need to perform a simple security relearn procedure, also known as a Passlock or anti-theft relearn. This can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online or in your vehicle’s service manual.
Where is the ECM located on a 2008-2010 Saturn VUE?
The ECM on the Saturn VUE is typically located in the engine compartment. For the 2.4L engine, it’s often on the right-hand (passenger side) firewall, and for the 3.6L, it can be found in a similar location. Always disconnect the battery before attempting removal or installation.
Will this part fit other GM vehicles?
Yes, this ECM is compatible with a wide variety of GM cars and trucks from this era. Please review the detailed fitment list on this page to confirm it matches your specific make, model, and engine option.
