Is your Saab 9-7X, Trailblazer, or Envoy plagued by frustrating engine problems? If you’re dealing with stalling, erratic shifting, a persistent check engine light, or a no-start condition, the root cause is often a failing Powertrain Control Module (PCM). This vital component is the brain of your vehicle, and when it falters, it can cause a cascade of issues that leave you stranded and stressed. This replacement PCM is your direct, reliable solution, arriving pre-programmed to your vehicle’s specific VIN to restore performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this module is the definitive fix:
- Engine stalling or cutting out intermittently
- Harsh or unpredictable automatic transmission shifting
- A significant drop in fuel economy
- Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0606)
- Engine misfires or rough idling
- Failure to pass an emissions test
- Complete no-start condition where the engine cranks but won’t fire

An Expert’s Note: From over 20 years of hands-on diagnostics, I’ve seen countless vehicles with persistent issues caused by mismatched control modules.

Our VIN-specific programming for this Programmed 2005-2006 Saab 9-7X PCM ensures every parameter is correct from the moment you plug it in, preventing a world of electronic headaches and getting the job done right the first time.
By installing this professionally programmed module, you are not just replacing a broken part—you are restoring the central nervous system of your vehicle. Regain the smooth performance and dependability you rely on with a Programmed 2005-2006 Saab 9-7X PCM that is built to last.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM comes fully programmed to the VIN you provide during checkout. It is designed to be a plug-and-play installation. In some cases, a simple security relearn procedure may be required, which can be done without any special tools and takes about 30 minutes.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is this a difficult part to install?
For someone with basic mechanical skills, this is a straightforward installation. The PCM is typically located in the engine bay on the driver’s side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and then installing the new one in the reverse order. It generally takes less than an hour.
What happens after I place my order?
After you complete your purchase, you will need to send us your vehicle’s VIN. Once we receive your VIN, our technicians will program the module with the latest GM software specific to your vehicle. The unit will then be securely packaged and shipped to you.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the PCM (indicated by codes like P0601, P0606, etc.), then this replacement module will solve the problem. However, if the light is on for another reason, such as a faulty sensor, that component will still need to be addressed separately.
Does this fit vehicles other than the Saab 9-7X?
Yes. This PCM is compatible with a wide range of GM SUVs from 2003-2006 that use the 4.2L inline 6-cylinder engine, including the Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Oldsmobile Bravada, and Isuzu Ascender. Please check the detailed fitment list on this page to confirm compatibility.
