An Expert’s Note on GM Luxury Platforms
The vehicles this module fits—like the Cadillac Deville, Seville, and Eldorado with the Northstar V8—are sophisticated machines. Their engine and transmission systems are intricately linked and controlled by the PCM. A generic or improperly programmed module can cause a cascade of issues that are difficult to diagnose. Using a professionally prepared Programmed 12573503 PCM that is flashed specifically to your car’s VIN is the single most important step in ensuring all related systems, from the variable valve timing to the electronic throttle control, function in perfect harmony as the engineers intended.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship your part until we receive the VIN, as the programming is specific to your car.
Is any additional programming required after installation?
While the core engine and transmission programming is complete, some vehicles may require a security relearn procedure (often called VATS or Passlock) and a Crankshaft Variation Relearn (CASE relearn). These are simple procedures that can often be done without a scan tool or by a local mechanic.
How do I know if this will fix my car’s problem?
This part will resolve issues directly caused by a failing PCM. It is crucial to have your vehicle properly diagnosed by a qualified technician to confirm the PCM is the point of failure before ordering. This module will not fix problems related to other faulty sensors or mechanical components.
Where do I find my part’s Service Number (SERV.NO)?
The service number is printed on the white sticker on your original PCM. This unit is compatible with SERV.NO 12573503, 12562481, 12571591, and 12573650. Our Programmed 12573503 PCM is the correct replacement for all of them.
Is this compatible with my 2006 Chevy SSR?
Yes, this electronic control module is the correct fit for the 2006 Chevrolet SSR, as long as the original part carries one of the compatible service numbers listed.
