An Expert’s Insight on Programming
As a technician, I can tell you that an unprogrammed ECM is just a metal box. It’s the software, tailored specifically to your vehicle’s VIN, that brings it to life. This programming tells the module everything it needs to know—from the engine and transmission type to the axle ratio and even the tire size. Our pre-flashing service isn’t just a convenience; it’s the most crucial step in ensuring a successful and lasting repair. We use the same tools and software as the dealership to ensure the Programmed 22819494 Engine Control Module integrates seamlessly with your vehicle’s entire electronic network.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. This module will arrive flashed with the latest GM software matched specifically to the VIN you provide.
How do I provide my VIN?
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.
Will this part be “plug and play”?
For most vehicles, yes. After installation, you may need to perform a simple security relearn procedure (often called a Passlock or Passkey relearn) or a crankshaft position sensor relearn. These procedures can typically be done without special tools and instructions are widely available.
How can I be sure my ECM is the problem?
Common signs of a faulty ECM include a check engine light with internal processor fault codes (P0601-P0606), intermittent stalling, no-start conditions, or multiple unrelated error codes. While these are strong indicators, we always recommend a full diagnosis by a qualified mechanic to confirm the ECM is the point of failure.
How do I confirm this fits my vehicle?
Please review the detailed fitment list on this page. The most reliable method is to match the part number from your original ECM to one of the numbers listed in our description, such as 22819494, 12668866, or 12643636.
