Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), often called the Engine Control Module (ECM), is your vehicle’s main computer. It controls all aspects of engine performance, fuel delivery, ignition timing, and automatic transmission shifting to ensure your car runs efficiently and smoothly.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the module to work in your car.
Is this a difficult part to install?
For most of the compatible vehicles, the PCM is located in the engine compartment and is held in by a few bolts. The installation typically involves disconnecting the battery, unplugging the electrical connectors from the old unit, swapping it with the new one, and reconnecting everything. It’s a straightforward job for a DIY mechanic with basic tools.
Will this fix my specific problem?
This module is a direct solution for issues caused by an internally failing computer, such as communication error codes, random stalling, and no-start conditions. While it fixes the most common electronic powertrain problems, we always recommend a proper diagnosis to confirm the PCM is the source of your issue.
My original part number is 12583826. Will this work?
Yes, this module is a fully compatible and updated replacement for original part numbers 12583827 and 12583826. Once programmed to your VIN, it will function identically to the original.
