Restore Your Vehicle’s Brain and Reclaim Your Drive
Is your vehicle suffering from confusing and frustrating issues like a persistent check engine light, rough idling, poor fuel economy, or even a no-start condition? These aren’t just annoyances; they’re signs that the very core of your vehicle’s command center—the Powertrain Control Module (PCM)—may be failing. This isn’t just a part; it’s the brain behind your engine’s performance and reliability. We offer a straightforward, dependable solution: a professionally programmed PCM, flashed with the latest GM software updates specifically for your vehicle’s VIN. Get back the confidence and peace of mind that comes from a vehicle you can trust.
Warning Signs and How to Overcome Them
A failing PCM can manifest in numerous ways, often leaving you stranded or second-guessing every trip. Here’s how our replacement module addresses these critical problems:
- ✔ Eliminates Troublesome DTCs: Directly resolves common diagnostic trouble codes such as P0601, P0602, P0603, P0604, P0605, and P0606, which point to internal computer failures.
- ✔ Restores Smooth Performance: Cures issues like engine stumbling, hesitation, and erratic transmission shifting by restoring precise control over fuel delivery and spark timing.
- ✔ Fixes No-Start Conditions: A faulty PCM can prevent the engine from starting altogether. This module restores the critical signals needed for ignition and fuel system operation.
- ✔ Improves Fuel Efficiency: By ensuring the engine runs exactly as the manufacturer intended, you’ll regain lost MPGs and save money at the pump.
- ✔ Plug-and-Play Installation: Because we program the unit to your VIN before shipping, you can avoid expensive trips to the dealership for flashing. A simple security relearn procedure is all that’s typically needed.
Guided Installation to Restore Peace of Mind
You don’t need to be a master mechanic to complete this repair. With a few basic tools and these simple steps, you can have your vehicle running properly again.
- Safety First: Always begin by disconnecting the negative terminal of your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most vehicles, the PCM is found in the engine compartment. For the Savana/Express vans, it’s typically on the driver’s side, rear of the engine compartment. For others, it may be under the battery tray or near the air filter box.
- Careful Removal: Gently 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 in the same location and securely reconnect the wiring harnesses. Ensure they click into place.
- Reconnect and Relearn: Reconnect the battery terminal. The final step is to perform the vehicle’s security relearn procedure (often called a Passlock or Passkey relearn), which syncs the new computer with your vehicle’s anti-theft system. This procedure is simple and instructions are readily available online for your specific model.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the part is shipped. We use your vehicle’s VIN to load the latest, most stable software from GM, making this a true plug-and-play solution. The only thing you may need to do is a simple security relearn procedure.
What is a security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It usually involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. Specific instructions for your model are easy to find online and do not require special tools.
Where do I find my 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.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the old PCM (like codes P0601-P0606), then yes, this part is the correct solution. However, if the light is on for another reason (e.g., a bad oxygen sensor), that issue will still need to be addressed separately.
What information do you need from me after I order?
After you complete your purchase, please send us your vehicle’s 17-digit VIN. This is crucial for us to program the module correctly for your specific vehicle configuration before we can ship it.
