In these 2004 GM vehicles, the PCM is the central hub for communication between dozens of other modules. Without the correct VIN, the anti-theft system (Passlock/VATS) won’t recognize your keys, the instrument cluster may not work, and the transmission can go into a ‘limp mode.’ We handle this critical step for you, ensuring that when you install our **2004 Yukon XL 1500 PCM 12586242**, it integrates seamlessly with your vehicle, just like the original part. ### Frequently Asked Questions **Do I need to do any programming after I receive this PCM?** No. This PCM comes fully programmed to your vehicle’s specific VIN number with the latest software updates from GM. It is ready for installation upon arrival. **How do I provide my VIN number?** After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship the part until we have programmed it with your VIN. **Will this fix my check engine light?** If the check engine light is caused by an internal fault within the original PCM (such as code P0601), this part will solve the problem. It is always recommended to have your vehicle properly diagnosed to ensure the PCM is the source of the issue before ordering. **Is a security relearn procedure required?** Yes, on most 2004 GM vehicles, you will need to perform a simple security relearn procedure after installation. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the PCM to sync with your vehicle’s anti-theft system. We include instructions for this easy process. **How can I confirm this part is correct for my vehicle?** The best way to confirm compatibility is to match the service number from your original computer to one of the numbers listed in our description (e.g., **12586242**, YFXM). This ensures you are ordering the correct hardware for your specific **2004 Yukon XL 1500 PCM 12586242** application. Please enter it in the payment notes and save to ensure we receive it.
