Is Your SAAB 9-7X Running Rough? The ECM Might Be the Culprit.
If you’re experiencing perplexing issues like unexplained stalling, poor fuel economy, a persistent check engine light, or a complete no-start condition in your 2007-2008 SAAB 9-7X, the root cause is often a failing Engine Control Module (ECM). As the central computer for your vehicle’s engine, the ECM controls everything from fuel mixture and ignition timing to transmission shifting. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose. Don’t let a faulty computer keep your powerful and unique SUV off the road.
This is a direct replacement Engine Control Module, part number 12630457, for your 2007-2008 SAAB 9-7X. The single greatest advantage of purchasing from us is our professional programming service. We flash the module with the latest GM-certified software updates specifically for your vehicle using the VIN you provide. This critical step ensures that the computer communicates perfectly with all other systems in your SAAB, eliminating the need for an expensive trip to the dealership for programming. It arrives at your door ready for a straightforward installation.
From the Diagnostic Bay
We had a 2008 SAAB 9-7X with the 5.3L V8 come in on a tow truck. The owner was at his wit’s end. The vehicle would start and run fine for about 15 minutes, then suddenly stall and refuse to restart for an hour. He had already replaced the fuel pump and crankshaft position sensor with no luck. After connecting our diagnostic scanner, we noticed erratic data from multiple sensors and communication dropouts with the ECM. We suspected internal failure. Instead of a costly new unit from the dealer, we sourced a quality replacement and programmed it to the vehicle’s VIN. After a simple security relearn procedure, the SAAB fired right up and ran perfectly. The owner was thrilled to have his vehicle back without the massive dealership bill.

Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
My original ECM has a different part number on it. Will this still work?
Yes, this part number 12630457 is an authorized service replacement for several earlier part numbers, including 12590032, 12602044, 12603530, and others listed in the description. It contains updated hardware and software for improved reliability.
Will this fix my specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, then this part will resolve them. It is crucial to ensure a proper diagnosis has been performed, as this module will not fix problems caused by other failing sensors or mechanical components.
