Frequently Asked Questions
Do I need to do any extra programming after installation?
No. This module is sent to you fully programmed to your vehicle’s VIN. In some cases, a security relearn procedure (often called a CASE relearn) may be necessary, which can typically be completed with a capable scan tool or by following a specific drive cycle. However, the core engine and transmission programming is complete upon arrival.
How do I provide you with my VIN?
Simply enter your 17-digit Vehicle Identification Number (VIN) in the notes section during checkout. If you forget, we will contact you via email to retrieve it before we can program and ship your module. We cannot ship without a VIN.
How can I be sure this fits my vehicle?
The best way to ensure compatibility is to match the part number from your old module to one of the numbers listed (16263494, 16265035, 8162634940). Please also review the detailed fitment list on this page. Providing your VIN allows us to perform a final verification.
What tools are needed for the installation?
Installation typically requires only basic hand tools, such as a socket set and ratchet, to remove the mounting bolts and disconnect the wiring harnesses. Always disconnect the vehicle’s battery before starting the replacement process for safety.
Will this fix my specific problem?
While this Programmed 16263494 PCM is the correct solution for a failed module, it’s crucial that your vehicle has been properly diagnosed. This part will not fix issues caused by faulty sensors, wiring, or other mechanical components. It specifically corrects problems originating from within the computer itself.
