Frequently Asked Questions
Do I need to do any programming myself?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This makes the installation process as simple as possible. In most cases, you will only need to perform a simple security relearn procedure, which does not require special tools.
How do I provide my VIN?
After you complete your purchase, please send us a message with your 17-digit VIN. You can also add it to the ‘notes to seller’ section during checkout. We cannot ship your part until we receive this information.
Will I need to perform a security or CASE relearn?
Yes, for most GM vehicles of this era, you will need to perform a security relearn procedure (also known as VATS or Passlock) after installation. This process syncs the new PCM to your vehicle’s anti-theft system and can typically be done in your driveway in about 30 minutes. A Crankshaft Variation (CASE) relearn may also be recommended to clear certain trouble codes and ensure optimal engine operation, which requires a compatible bi-directional scan tool.
Is this a brand new part?
This is a high-quality, fully tested replacement module that is guaranteed to meet or exceed original equipment specifications for performance and long-term reliability. Every unit is inspected and prepared to ensure it’s ready for service.
How can I be sure this fits my vehicle?
Please review the detailed fitment list provided in this listing. The most important step is to match the part number 16263494 PCM or one of the other compatible numbers listed. If you are still unsure, please contact us with your VIN and we will be happy to verify compatibility for you.
