Restore Peak Performance to Your GM SUV
Are you battling a persistent check engine light, rough idling, or frustrating stalling in your Saab 9-7X, Trailblazer, or Envoy? A failing Powertrain Control Module (PCM) is often the culprit, leaving you with an unreliable vehicle and a major headache. This isn’t just an inconvenience; it’s a matter of dependability. We offer the definitive solution: a professionally programmed PCM, flashed with the latest GM software updates and tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This is the key to getting your truck back on the road and running exactly as it should.
Common Symptoms of a Failing GM PCM & Your Solution
If your vehicle is experiencing any of the following issues, a faulty engine computer is a likely cause. This pre-programmed unit is designed to be the direct solution for these problems:
- Persistent Check Engine Light: Especially with diagnostic trouble codes (DTCs) like P0601, P0602, P0606, or other internal processor faults.
- Engine Stalling or Misfiring: Unexpected stalling at stops or hesitation during acceleration.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the PCM.
- Poor Fuel Economy: A failing module can’t properly manage the air-fuel mixture, leading to wasted gas.
- Erratic Transmission Shifting: The PCM communicates with the transmission controller; a fault can cause harsh or incorrect shifts.
Replacing your old module with our professionally programmed 2005-2006 Saab 9-7X PCM is the most effective way to permanently resolve these issues and restore your vehicle’s original performance and reliability.

An Expert’s Note on GM Security Systems
“One of the biggest frustrations for DIY mechanics working on these GM SUVs is the Vehicle Anti-Theft System (VATS). A generic, non-programmed computer will often trigger the security system, preventing the vehicle from starting. Because we program this 2005-2006 Saab 9-7X PCM to your exact VIN before shipping, it correctly syncs with your vehicle’s Body Control Module (BCM) and ignition key. This simple but critical step saves you hours of troubleshooting and the potential need for a costly ‘security relearn’ procedure at a dealership.”- Veteran Automotive Diagnostician
Frequently Asked Questions
What information do you need from me?
After you place your order, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program the module correctly.
Is any additional programming required after installation?
No. This PCM is a true plug-and-play solution. Because it has been pre-flashed to your VIN, it is ready to work as soon as it is installed. In most cases, you will not need to perform any additional procedures.
Where can I find my VIN?
Your VIN can be found on a metal tag 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.
Will this fit my Chevy Trailblazer or GMC Envoy?
Yes. While the primary model is the Saab 9-7X, this PCM is compatible with a wide range of GM SUVs from 2003-2006, including the Trailblazer, Envoy, Rainier, Bravada, and Ascender equipped with the 4.2L engine. Please check the detailed fitment list to confirm your specific model and year.
How difficult is the installation?
Installation is straightforward for someone with basic mechanical skills. The PCM is typically located in the engine bay on the driver’s side. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. The new unit installs in the reverse order. We always recommend consulting a repair manual for your specific vehicle.
