Expert Insight: The Importance of Correct Programming
As a technician, I’ve seen countless vehicle owners try to save a few bucks by installing a used computer from a salvage yard. More often than not, it leads to more problems. Anti-theft systems engage, transmissions won’t shift correctly, and the engine runs poorly because the module is programmed for a different vehicle’s options and emissions. Our process eliminates that guesswork. By programming the 2003 Savana 2500 PCM 12576106 to your specific VIN, we ensure all the complex software parameters match your vehicle perfectly, just like a new part from the factory.
Frequently Asked Questions
Do I need to do any programming after I receive this PCM?
No. This PCM is shipped to you pre-programmed to the VIN you provide. However, on many GM vehicles, you will need to perform a security relearn procedure (often called Passlock or Passkey) and a Crankshaft Position Sensor (CASE) relearn. These procedures can typically be done with a capable bi-directional scan tool and are required for the vehicle to start and run correctly.
Where do I provide my vehicle’s VIN?
Please provide your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout or send it to us in a message after you place your order. We cannot program and ship your module without it.
Is this a brand new part?
This is a high-quality replacement component that has been meticulously inspected and prepared to meet or exceed original equipment performance. It is programmed with the latest official GM software for your vehicle.
