Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential. It allows us to access the exact GM software calibration file for your van’s specific engine, transmission, and options. Programming this programmed 2016 Express 3500 ECM with your VIN ensures it communicates perfectly with your vehicle’s other modules, just like the original.
Is any additional programming needed after installation?
In most cases, no further programming is required. This module is sent ready for installation. However, some vehicles may require a simple security relearn procedure (often called a key relearn or anti-theft relearn) which can typically be done without special tools. Instructions are widely available online for this process.
Is this a difficult part to install?
The physical installation is generally straightforward for someone with basic mechanical skills. The ECM is typically located in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. The key is to handle the connectors with care. Always disconnect the battery before starting work.
Will this fix my check engine light?
If the check engine light and performance issues are caused by a faulty ECM, this part is the correct solution. After installing the new module, it is a good practice to clear any old codes from the system with a standard code reader to ensure a fresh start. This programmed 2016 Express 3500 ECM is designed to resolve internal computer faults.
How does the one-year warranty work?
This unit is backed by our one-year replacement warranty. If the module fails within one year from the date of purchase, we will provide a replacement unit. The warranty covers the part itself and is designed to give you confidence in your repair.
