An Expert’s Note: Many drivability issues in these GM trucks and SUVs are caused by outdated factory software. Simply replacing a faulty PCM with another one running old code might not fix the root cause. We ensure every module is loaded with the most current GM calibration for your specific VIN. This not only fixes the component failure but also provides critical updates that can solve underlying problems with idle stability and transmission logic that the original software may have had.
Frequently Asked Questions
Do I need to get this PCM programmed?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide us with your vehicle’s VIN after purchase, and it will arrive ready to install.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is very manageable. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in the reverse order. In some cases, a security relearn procedure may be required, which can be done without special tools.
Where do I find my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, your insurance card, or on a placard on the driver’s side of the dashboard visible through the windshield.
How do I confirm this fits my vehicle?
This unit replaces service numbers 12586242, 19299226, 89017738, and many others listed in the description. As long as your vehicle is on the fitment list and we program it to your VIN, it will be the correct computer for your truck or SUV.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (common diagnostic codes include P0601-P0606), then this part is the correct solution. However, it’s always best to have the codes professionally diagnosed to ensure the problem isn’t a faulty sensor or wiring issue.
What is the warranty for this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your repair.
