Restore Your Vehicle’s Performance and Reliability
Are you battling frustrating and unpredictable engine problems with your Saab 9-7X, Trailblazer, or Envoy? A faulty Powertrain Control Module (PCM) can be the hidden cause of issues like stalling, no-start conditions, poor fuel economy, and persistent check engine lights. This engine computer is the definitive, hassle-free solution to get your truck back on the road, running exactly as it should. We eliminate the guesswork and the expensive trip to the dealership by pre-programming this unit specifically for your vehicle using your VIN.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing PCM is the likely culprit. This unit is designed to resolve these exact problems:
- No-Start or Hard Starting: The engine cranks but refuses to start, or takes an excessively long time to fire up.
- Unexplained Stalling: Your vehicle stalls intermittently, often at idle or during low-speed driving.
- Check Engine Light with Communication Codes: You may see diagnostic trouble codes (DTCs) like P0601, P0606, or U-series codes, indicating internal computer failure.
- Erratic Transmission Shifting: The PCM controls transmission logic, and a failure can lead to harsh or incorrect gear changes.
- Reduced Power and Poor Fuel Economy: A malfunctioning computer can’t properly manage engine parameters, leading to a noticeable drop in performance and efficiency.

Expert Insight: The “CASE Relearn” Procedure
After installing your new Programmed Saab 9-7X PCM 12574976, your vehicle may require a Crankshaft Position System Variation Learning procedure, often called a “CASE relearn.” This is a simple calibration that syncs the new PCM with your engine’s crankshaft position sensor. While many vehicles will run fine without it, performing this procedure with a capable scan tool will prevent a P1336 trouble code and ensure the most accurate misfire detection. It’s a quick final step that guarantees your repair is 100% complete and your engine runs at peak smoothness and efficiency.
Frequently Asked Questions
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the computer correctly for your specific vehicle configuration.
Is any additional programming required after installation?
No. This PCM arrives fully programmed and ready for installation. In some cases, a CASE relearn (Crankshaft Position Variation Learn) may be needed to clear a specific code, which can be done with a compatible scan tool. However, the core programming is complete.
Will this fix my vehicle’s security system (Passlock/VATS)?
Our programming addresses the engine and transmission functions. On these GM vehicles, the security information is often stored in the Body Control Module (BCM). After installation, you may need to perform a simple security relearn procedure, which typically involves cycling the key in the ignition. This procedure takes about 30 minutes and requires no special tools.
