An Expert’s Note on Installation: After installing your new PCM, you will need to perform a security relearn procedure (often called a ‘key relearn’). This is a simple process that syncs the new computer with your vehicle’s anti-theft system and typically takes about 30 minutes with just your ignition key. Instructions are readily available online, and this final step is what allows you to bypass the dealership completely, saving you significant time and money. This is a critical step for a successful 2004 Suburban 1500 PCM replacement.
Frequently Asked Questions
Is this computer difficult to install?
No. On a 2004 Suburban, the PCM is located in the engine bay, on the driver’s side under the battery. Installation involves disconnecting the battery, removing the old unit, installing the new one, and reconnecting the battery. The final step is the security relearn, which does not require special tools.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot program and ship your computer without it.
Is this really plug and play?
Yes, in the sense that no dealer programming or special computer flashing is required. It arrives ready to be installed. However, you must perform the vehicle’s security relearn procedure to sync the PCM with your keys and anti-theft system.
Will this fit other vehicles besides the Suburban?
Absolutely. This PCM, service number 12586242, fits a wide range of 2004 GM trucks and SUVs, including the Sierra, Silverado, Tahoe, Yukon, Escalade, Hummer H2, and more. Please check the detailed fitment list on this page to confirm compatibility.
What if I have aftermarket modifications on my truck?
This PCM is programmed with the original factory calibration for a stock vehicle. It is not designed to accommodate significant aftermarket modifications like different injectors, camshafts, or forced induction systems.
