Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for programming the module correctly.
Is this ECM difficult to install?
For someone with moderate mechanical skill, the installation is straightforward. The ECM is typically located in the engine compartment and is secured with a few bolts and electrical connectors. However, we always recommend consulting a service manual for your specific vehicle. The key benefit is that the complex programming is already done for you.
Will this part require any additional procedures after installation?
In some GM vehicles, a security relearn procedure (often called a CASE relearn or anti-theft relearn) may be required after installation. This is a simple process that can typically be done without special tools and involves a sequence of key turns. Instructions are widely available online for specific models.
How can I be sure this will fix my car’s problem?
While this ECM is the solution for a wide range of symptoms, proper diagnosis is key. We recommend you or your mechanic confirm the ECM is the point of failure. Common indicators include specific diagnostic trouble codes (DTCs) related to the processor or communication errors that persist after checking wiring and sensors.
What does ‘plug and play’ mean for this part?
It means the module arrives with the correct software and calibration for your specific vehicle, loaded via your VIN. You can install it, connect the battery, and in most cases, start the car. It eliminates the need for a trip to the dealer for expensive, post-installation programming.
How does the one-year replacement warranty work?
Our warranty is simple. If the module fails within one year of the purchase date, we will provide a replacement unit. This gives you confidence and protection for your investment.
