Frequently Asked Questions
Do I need to have this module programmed?
No. This PCM comes fully programmed to your vehicle’s VIN before we ship it. It is ready to be installed right out of the box, saving you the time and expense of a dealership visit.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is any other setup required after installation?
In some GM vehicles of this era, a security relearn procedure (often called Passlock or VATS) may be required to sync the new PCM with your vehicle’s anti-theft system. This is a simple procedure that typically takes 10-30 minutes and does not require any special tools. We can provide instructions for this process.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) is most accurate for this part as it controls both the engine and transmission. ECM (Engine Control Module) typically controls only the engine. ECU (Electronic Control Unit) is a more generic term for any electronic module in a vehicle.
Will this fix my transmission shifting problems?
If your transmission issues are caused by faulty signals or processing from a failing PCM, then yes, this part will resolve them. The PCM controls shift points and line pressure based on sensor inputs, so a healthy module is critical for proper transmission function.
What part numbers does this module replace?
This module is a direct replacement for part number 12576160 and is also fully compatible with service numbers 12200411, 12201281, and 52369718.
