Is your GM vehicle suffering from a persistent check engine light, erratic shifting, stalling, or a frustrating no-start condition? These aren’t just annoyances; they’re symptoms of a failing Engine Control Module (ECM), the central computer of your vehicle. This isn’t just another replacement part; it’s the definitive, pre-programmed solution to restore your vehicle’s performance, reliability, and your peace of mind on the road.

Frequently Asked Questions
Do I need to do any additional programming myself?
No. This module arrives fully programmed to the VIN you provide. In some cases, a simple “CASE Relearn” or security relearn procedure may be required after installation, which can be performed with many professional-grade scan tools.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your part until we have this information to program the module correctly.
Is this part difficult to install?
For many DIYers with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to replace it with the new one. Location varies by model, so we recommend consulting a repair manual for your specific vehicle.
