Frequently Asked Questions
Do I need to do anything special after I install this PCM?
In most cases, you will need to perform a simple security relearn procedure after installation. This procedure can be done without any special tools and typically involves a sequence of turning the key in the ignition. Instructions are readily available online or we can help guide you.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module before we can ship it.
Is this a new or used part?
This is a high-quality, fully tested replacement module that is guaranteed to meet or exceed original equipment specifications. Each unit is meticulously inspected and prepared to ensure reliability.
Will this definitely fix my Check Engine Light?
If the check engine light is caused by an internal failure of your original PCM (as indicated by codes like P0601, etc.), this part is the correct solution. However, if the light is on for another reason, such as a faulty sensor, that issue will need to be addressed separately.
What if I order the wrong part for my vehicle?
Because we program each module to your specific VIN, it’s crucial to ensure compatibility before ordering. Please check the fitment list carefully. If you are unsure, contact us with your VIN and we will be happy to verify the correct part for you.
How long does the programming and shipping process take?
Programming is typically completed within 1-2 business days after we receive your VIN. Once programming is complete, the module is shipped out promptly via the shipping method you select at checkout.
