Expert Insight: The Importance of Correct Programming
For sophisticated platforms like the Cadillac Northstar V8 and the LS-based engines found in the SSR, the PCM’s software is not one-size-fits-all. A generic or improperly flashed module can lead to a cascade of new problems, from incorrect transmission behavior to unresolved engine codes. Our process ensures the Programmed 12573503 PCM you receive has the exact calibration intended by GM for your specific model, year, and options. This precision is the key to a successful repair and the secret to restoring that ‘like-new’ driving feel.
Take the guesswork out of your repair. This module is the most reliable way to solve complex electronic issues and get your vehicle back on the road with the performance and confidence you deserve. Simply provide your VIN upon purchase, and we’ll handle the complex programming for you.
Frequently Asked Questions
Do I need to do any programming after I receive this?
No. This module is fully programmed to your vehicle’s VIN before it ships. In most cases, you will only need to perform a simple security relearn procedure, which involves a series of key cycles and requires no special tools.
Where do I provide my vehicle’s VIN?
You can add your VIN to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it. We cannot ship the part until we have programmed it.
Will this fit my car? It has a different service number.
This Programmed 12573503 PCM is the correct, updated replacement for several older service numbers, including 12562481, 12571591, and 12573650. As long as your vehicle is listed in the compatibility chart, this is the correct part for you.
What is the security relearn procedure?
It is a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this sequence three times. Instructions are readily available online for your specific model.
Will this fix my transmission shifting problems?
In many GM vehicles, the PCM controls both the engine and the transmission. If your shifting issues are caused by faulty electronics within the module, this part is very likely to be the solution. However, proper diagnosis is always recommended to rule out mechanical issues.
