Restore Your Vehicle’s Brainpower and Performance
Is your 2007-2008 SAAB 9-7X, Chevy Trailblazer, GMC Envoy, or other compatible GM truck exhibiting strange and frustrating behavior? Issues like erratic shifting, poor fuel economy, a no-start condition, or an illuminated Check Engine Light can often be traced back to a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing everything from engine timing and fuel injection to transmission shifting and emissions control. When it fails, the entire vehicle’s performance suffers. This listing is for a direct replacement PCM, part number 19210067, that arrives at your door fully programmed and ready for installation.
From the Diagnostic Bay
We had a 2007 GMC Envoy with the 4.2L engine come into the shop a few weeks ago. The customer was at his wit’s end. The truck would randomly stall at stoplights, the transmission would get stuck in gear, and a host of seemingly unrelated trouble codes were popping up. He had already replaced the throttle body and a few sensors with no luck. We hooked up our scanner and saw communication errors with the PCM. After confirming the module’s power and ground connections were solid, we knew the internal circuitry of the PCM was compromised. Instead of a costly and time-consuming trip to the dealer, we ordered a pre-programmed unit like this one. Once it arrived, the physical swap took less than 30 minutes. After performing the security relearn, the truck started right up and ran perfectly. All the ghost codes were gone, and the customer was thrilled to have his reliable vehicle back. A failing PCM can mimic many other problems, but a correctly programmed replacement is often the definitive solution.
Symptoms of a Failing Powertrain Control Module
- ✔ Check Engine Light is on with various communication or sensor-related codes (e.g., U-codes, P0606).
- ✔ The engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Engine stalling, stuttering, or misfiring unexpectedly.
- ✔ Failure to pass an emissions inspection.
- ✔ Other modules in the vehicle (like the BCM or TCM) report a loss of communication with the PCM.
Why Choose Our Programmed 2007-2008 SAAB 9-7X PCM?
Getting your truck or SUV back on the road shouldn’t be a complicated ordeal. Our process is designed to be simple, effective, and reliable. This isn’t just a generic, off-the-shelf part. We take your vehicle’s specific Vehicle Identification Number (VIN) and flash this PCM with the latest, most stable software updates directly from GM. This ensures that the module is perfectly matched to your vehicle’s original configuration, including its engine, transmission, and emissions equipment. This critical programming step eliminates compatibility issues and ensures optimal performance from the moment of installation.
This module is a direct fit for a wide range of GM vehicles built on the GMT360 platform. While this listing focuses on the SAAB 9-7X, it is also the correct part for models like the Isuzu Ascender, Chevy Colorado, GMC Canyon, Hummer H3, and Buick Rainier. Always verify that your original module’s part number is 19210067 for guaranteed compatibility.
Installation and Security Relearn
Physically replacing the PCM is straightforward. It is typically located in the engine bay and is secured with a few bolts and electrical connectors. However, after installation, you will need to perform a security relearn procedure. This allows the new PCM to communicate with your vehicle’s anti-theft system and ignition keys. This procedure is simple and does not require a specialized scan tool. It typically involves a sequence of turning the key in the ignition. We include instructions to guide you through this final step, making the installation process manageable for a competent DIY mechanic.
Frequently Asked Questions
Do I need to send my old PCM in?
No, there is no core charge or need to send your original module to us. This is a direct purchase of a replacement part.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship the module without it. The VIN ensures we load the exact correct software for your truck’s specific options.
Is this module difficult to install?
The physical installation is relatively simple for someone with basic mechanical skills, usually taking less than an hour. The most critical part is performing the security relearn procedure after the new PCM is installed, for which we provide clear instructions.
Will this fix my vehicle’s problem?
This PCM will resolve issues directly caused by a faulty engine computer. While the symptoms listed are common indicators of PCM failure, it is essential to have your vehicle properly diagnosed. We recommend checking power, grounds, and the communication network to the PCM before ordering to confirm it is the point of failure.
What if my part number is slightly different?
This module, 19210067, also supersedes part number 12602010. If you have a different part number, please contact us before ordering to ensure we can provide a compatible unit for your vehicle.
