Restore Peak Performance to Your Cadillac
Is your Cadillac Seville suffering from frustrating and unpredictable issues like a persistent check engine light, harsh shifting, stalling, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the electronic brain of your vehicle. Don’t let a faulty computer compromise the smooth, powerful ride you expect. This fully programmed PCM is the definitive, reliable solution to restore your vehicle’s performance and your driving confidence.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often leading to incorrect diagnoses and expensive, unnecessary repairs. If you’re experiencing any of the following, your PCM is the likely culprit:
- Erratic or harsh automatic transmission shifting
- Unexplained engine stalling or stumbling
- Complete no-start condition where the engine cranks but won’t fire
- Poor fuel economy and loss of power
- Illuminated Check Engine Light with communication error codes (e.g., P0601, P0606)
This replacement unit is the direct answer to these problems. We take the guesswork out of the repair by pre-programming this module specifically to your car’s Vehicle Identification Number (VIN). This ensures that once installed, it communicates perfectly with your engine, transmission, and security systems, making it a true plug-and-play solution.

Frequently Asked Questions
Do I need to do any additional programming myself?
No. This module is a complete plug-and-play solution. We program it using your vehicle’s VIN before it ships, so it’s ready for installation as soon as you receive it. In some rare cases, a Crankshaft Variation Relearn procedure may be needed, which can be done with a capable scan tool.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to submit it. We cannot ship your order until we receive and validate your VIN.
How do I know if this is the exact part for my car?
The best way to confirm compatibility is to match the service number (SERV.NO) on your original computer’s sticker to one of the numbers listed: 12573503, 12562481, 12571591, or 12573650. This listing for the 2000-2003 Cadillac Seville PCM 12573650 covers all these service numbers.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s shift points and line pressure. If your transmission issues are electronic in nature and caused by a failing computer, this part is the correct solution.
What is your warranty policy on this part?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself for a full year from the date of purchase.
