Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This PCM comes fully programmed to the VIN you provide. The only additional step required after installation is a simple security relearn procedure that you can do yourself with just the ignition key. We provide clear instructions for this process.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive an email with instructions on where to send your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
What is the security relearn procedure?
It’s a simple process that syncs the new PCM with your vehicle’s anti-theft system. It typically involves cycling the ignition key on and off in a specific sequence for about 30 minutes. No special tools are required, and detailed instructions are included with your order.
Will this PCM fix my specific problem?
This module is a direct solution for a failed PCM. While it resolves the vast majority of electronic and drivability issues listed above, it’s always best to have a proper diagnosis performed to rule out other potential causes like faulty wiring or sensors. Our technicians are available to help if you have diagnostic questions.
