Frequently Asked Questions
Do I need to do any additional programming after installation?
No. This ECM arrives pre-programmed to your vehicle’s VIN. In most cases, it is a direct installation. However, some vehicles may require a security relearn procedure (often called a key relearn or anti-theft relearn), which can typically be done without special tools. Instructions are readily available online for most models.
How do I provide my VIN number?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship the module without this information. Please double-check the VIN for accuracy before sending.
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 bay and is secured with a few bolts and electrical connectors. Always disconnect the battery before beginning the installation. If you are not comfortable performing the repair, we recommend consulting a qualified mechanic.
Will this fix my specific problem?
This module is a direct solution for a failed ECM. While it resolves the common symptoms listed, it’s crucial to have your vehicle properly diagnosed to confirm the ECM is the source of the issue. This part will not fix problems caused by other faulty sensors or wiring.
