Frequently Asked Questions
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a security relearn procedure (also known as a CASE relearn or anti-theft relearn). This process syncs the new PCM with your vehicle’s anti-theft system and can typically be done without special tools. Instructions are widely available online for your specific model.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your module until we receive this information. Please double-check it for accuracy.
Is this a brand new part?
This is a quality, inspected, and tested component that has been expertly programmed to function to original equipment standards. It provides a reliable and cost-effective alternative to a new dealership part.
Will this fix my specific check engine light codes?
This PCM is a direct solution for internal module failure codes like P0601, P0602, and P0606. If your codes are related to sensors or other components, you must fix those issues as well. A faulty PCM is often the root cause, but proper diagnosis is always recommended.
What if my original part number isn’t on the list?
The service numbers listed (e.g., 89017750, 12582605, 12602802) are the most common, but this module is compatible with a wide range of vehicles. As long as your vehicle is on the fitment list, we can program this PCM to work perfectly for you using your VIN.
Where is the PCM located on my vehicle?
On most of these GM trucks and SUVs (Silverado, Tahoe, Escalade, etc.), the PCM is located in the engine bay, on the driver’s side, under or next to the battery tray.
