Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions to reply with your 17-digit Vehicle Identification Number (VIN). We must have your VIN to program the module correctly before we can ship it.
Is this part truly ‘plug and play’?
Yes, for most vehicles on the fitment list. Because we pre-program it to your VIN, you can typically install it and start the vehicle. However, some GM vehicles may require a simple ‘Security Relearn’ procedure, which involves turning the key on and off a few times. Instructions are readily available online and it does not require any special tools.
What if my original part number is not on your list?
The service numbers listed are the most common ones this module replaces. If your number is different but your vehicle’s make, model, and year are listed, please contact us with your VIN. We can verify compatibility for you to ensure you get the correct part.
Do I need to send my old PCM (core) back?
No core charge or core return is required for this part. You can keep or responsibly dispose of your old module.
What does ‘flashed’ or ‘programmed’ mean?
This means we load the module with the specific software your vehicle needs to operate. This software, based on your VIN, controls everything from fuel injection and spark timing to transmission shifting. Without correct programming, the part will not work in your vehicle.
