End the Frustration of a Failing Engine Computer
Is your vehicle suffering from baffling electrical issues, a persistent check engine light, or unpredictable performance? A faulty Powertrain Control Module (PCM) can be the hidden culprit, causing everything from poor fuel economy and rough idling to a no-start condition that leaves you stranded. It’s a frustrating experience that erodes your confidence in your car. This is your direct-fit, fully programmed solution to restore your vehicle’s health and your peace of mind.
Guided Installation to Restore Peak Performance
We’ve made this repair as straightforward as possible. This module arrives pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN), eliminating the need for an expensive trip to the dealership. Just follow these simple steps to get back on the road.
- Safety First: Begin by disconnecting the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate and Remove: Find the old PCM. Its location varies by model (e.g., LH front engine compartment on a G6, under the battery on a Silverado). Carefully unplug the wiring harnesses and unbolt the module from its bracket.
- Install the New Module: Mount your new, pre-programmed PCM securely in place. Reconnect the wiring harnesses, ensuring each plug clicks firmly into its socket.
- Power Up: Reconnect the negative battery terminal. The vehicle is now ready for the final steps.
- Final Sync: In some cases, a security or CASE (Crankshaft Angle Sensor Error) relearn procedure may be required. This can often be done with a simple key cycle procedure or a common scan tool, syncing the new computer with your vehicle’s systems.

A Mechanic’s Note: The Dealership Alternative
“I had a customer with a 2009 Malibu whose car would randomly stall at traffic lights. They were quoted over a thousand dollars by the dealership for a new computer and programming. They were stressed and felt trapped. I ordered one of these pre-programmed units for them. The installation took less than 30 minutes in their driveway. The moment the engine fired up and idled smoothly, the look of pure relief on their face was priceless. They saved a significant amount of money and, more importantly, regained a car they could trust.”

Frequently Asked Questions
Do I need to get this computer programmed?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN after you place your order, and it will arrive ready to install with the latest GM software updates for your specific car.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. You can typically find it on a small plate on the driver’s side of the dashboard (viewable through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will I need to perform a security relearn procedure?
In many GM vehicles, a security relearn (also known as a Passlock or anti-theft relearn) is necessary to sync the new PCM with your vehicle’s keys and security system. This is typically a simple procedure involving a few cycles of the ignition key and does not require special tools.
How do I find my original part number?
The service number is printed on a sticker on your original computer. However, as long as your vehicle model and year are on our compatibility list, this module will work, as it replaces a wide range of original service numbers.
What if my exact service number isn’t listed?
The service numbers provided (e.g., 12597125, 12612397) are common examples. This PCM is the correct hardware for all vehicles in the fitment list. We program it to function identically to your original, regardless of the specific service number.
