Expert Technician’s Insight
As a technician with over two decades of experience, I’ve seen countless DIYers get stuck with a junkyard PCM that won’t work because it isn’t programmed. For these 1996 GM vehicles, the PCM is the central nervous system. It controls everything from the fuel injectors to the transmission shift points. By programming this module specifically to your VIN, we ensure all the factory settings and component calibrations are correct from the moment you install it. It’s the difference between a quick, successful repair and a week of headaches.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians will then use this information to flash the module with the correct, updated software from GM for your specific car before we ship it.
Is this really a plug-and-play installation?
Yes. Because the unit arrives pre-programmed to your VIN, the installation is straightforward. You simply need to disconnect the vehicle’s battery, remove the old module, install the new one, and reconnect the battery. No further programming is required.
Will this fix my specific check engine light codes?
This 16231853 PCM is the direct solution for internal module failure codes (like P0601 through P0606) and communication errors. While it can resolve issues that cause other codes, it’s essential to ensure your vehicle’s sensors and wiring are in good condition. Proper diagnosis is key to any successful repair.
What part numbers does this module replace?
This unit is a direct replacement and is compatible with the following GM service numbers: 88963800, 16211539, and 16231853.
Do I need to perform a security relearn procedure?
For most 1996 GM models this unit fits, a security relearn is not typically required as the security information is not stored in the PCM. It is a simple plug-and-play installation. However, we always recommend consulting a service manual for your specific vehicle if you are unsure.
