Restore Your Van’s Heartbeat and Your Peace of Mind
Is your work van or daily driver suddenly unreliable? A flickering check engine light, rough idling, or a frustrating no-start condition can throw your entire day off track. These aren’t just minor annoyances; they’re signs that your vehicle’s brain—the Powertrain Control Module (PCM)—may be failing. It’s the central command for your engine’s performance, fuel economy, and emissions. When it falters, everything falters. This replacement PCM, service number 12597125, is the definitive solution to get you back on the road with confidence and without the exorbitant dealership price tag.
Warning Signs Your PCM Needs Attention
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, it’s time to consider the source. This unit is the solution for:
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601, P0602, P0606.
- ✔ Unexplained drops in fuel efficiency.
- ✔ Engine stalling, sputtering, or misfiring intermittently.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Failure to communicate with diagnostic scan tools.
Guided Installation for a Confident Fix
We believe you shouldn’t need a master mechanic’s toolkit to restore your vehicle’s reliability. This module is designed for a straightforward swap. After we program it with your vehicle’s VIN, it’s ready to go. Follow these simple steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow the system to fully discharge.
- Locate the Old Module: On most Savana and Express vans, the PCM is located in the engine compartment on the driver’s side, often near the battery or air filter box.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the old module from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed PCM securely onto the bracket. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Power Up: Reconnect the negative battery terminal. The vehicle may require a security relearn procedure, which is a simple process of cycling the key. We include instructions for this!
An Expert’s Note: The Dealership Alternative
“I once had a local contractor come in with his ’08 Savana work van. It was stalling randomly, costing him jobs and endless frustration. The dealership quoted him over a thousand dollars for a new PCM plus programming and labor. He was about to give up on the van. We provided him with one of our pre-programmed modules. In under an hour, he had swapped it himself in his own driveway. The van fired right up and ran smoother than it had in years. He saved a ton of money and, more importantly, got his business back on the road without delay. That’s the real-world value of a reliable, plug-and-play solution.”

Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the process of loading your vehicle’s specific software and calibrations onto the replacement PCM. This includes information about your engine, transmission, tire size, and factory options. It ensures the module communicates perfectly with all other systems in your vehicle, just like the original one did.
Do I need to do anything after installation?
In most cases, the module is plug-and-play. However, some GM vehicles require a simple security relearn procedure, also known as a CASE relearn, to sync the new PCM with the anti-theft system. We provide easy-to-follow instructions for this process, which typically involves a few cycles of the ignition key.
Is this a brand new part?
This is a high-quality, fully tested replacement part that has been meticulously inspected and prepared to meet or exceed original equipment specifications. It is loaded with the latest GM-certified software for your vehicle.
Where is the PCM located on my 2009 Savana 1500?
On the 2008-2009 Savana 1500, the Powertrain Control Module is typically found in the engine compartment, mounted on the driver’s side near the battery or inside the air cleaner assembly box.
How do I send you my VIN?
After you complete your purchase, you can send us your 17-digit Vehicle Identification Number (VIN) through the messaging system or add it as a note during checkout. We cannot ship your part until we receive your VIN, as programming is the first step in our fulfillment process.
