An Expert’s Note on Programming
As a technician, I’ve seen countless vehicle owners buy a used computer from a salvage yard, hoping for a cheap fix. The problem is that a PCM is not a one-size-fits-all part. It’s coded specifically to the VIN of the vehicle it came from, including its options, transmission, and security system. Installing a non-programmed module will, at best, not work and, at worst, can create even more electronic headaches. Our process of programming this 2004 SSR PCM 12586242 to your specific VIN before it ships eliminates that entire gamble, giving you a part that works correctly right out of the box.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is any additional programming needed after installation?
In most cases, no. This module is sent ready for installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or Passlock relearn), which can typically be done without special tools. Instructions are widely available online for this simple process.
My original part number is different, but it’s on your list. Will this work?
Yes. Manufacturers often use multiple part numbers or service numbers for the same component. As long as your vehicle’s make, model, year, and original part number are included in our compatibility list, this module will be the correct, programmed replacement for your vehicle.
Where is this module located on my vehicle?
For most of the compatible vehicles like the Trailblazer, Envoy, and SSR, the module is located in the engine bay, next to the air filter box. For trucks like the Silverado and Sierra, it is typically found under the battery on the driver’s side front corner. Always disconnect the battery before attempting to replace the module.
What if I have questions during installation?
Our team is here to help. While we cannot diagnose your vehicle remotely, we can offer guidance related to the installation of the part you’ve purchased from us. Your purchase of a 2004 SSR PCM 12586242 is supported by our knowledgeable staff.
