Expert Mechanic’s Tip: Before installing your new PCM, take a moment to inspect and clean your vehicle’s main battery cables and chassis grounds, especially the ground strap from the engine block to the frame. A poor ground connection can cause voltage drops and communication errors that can mimic PCM failure and damage a new module. A few minutes of preventative maintenance can ensure a successful, long-lasting repair.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
Yes. While the module comes programmed to your VIN, you will need to perform a security relearn procedure (often called VATS relearn) so the module recognizes your keys. This is a simple procedure that typically takes 10-30 minutes and does not require special tools. Additionally, a Crankshaft Position Sensor (CASE) relearn may be needed with a capable scan tool to clear a P1336 code, though the vehicle will run and drive without it.
How do I provide my VIN number?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module until we receive this information.
Is this part compatible with other part numbers?
Yes, this module is a direct replacement for several service numbers, including 12200411, 12201281, and 52369718. As long as your vehicle is on the compatibility list, this PCM will function correctly once programmed to your VIN.
Will this fix my specific problem?
This PCM will correct any issue originating from a faulty computer. If you have DTCs like P0601 (Internal Memory Fault) or no communication with the module, it is almost certainly the solution. However, it’s always best practice to properly diagnose your vehicle to ensure the PCM is the root cause of the problem and not a wiring or sensor issue.
What is the warranty on this part?
This part comes with a standard warranty that covers any defects in the module itself. Please refer to the warranty section of the listing for specific terms and duration. Proper diagnosis and installation are key to a lasting repair.
