Restore Your Vehicle’s Brain and End Frustrating Engine Problems
Real-World Repair Story
I remember a 2002 Pontiac Grand Am with the 3.4L V6 that came into my shop. The owner had replaced the plugs, wires, and even the fuel pump chasing an intermittent stalling issue. It would run fine for days, then die at a stoplight without warning. No consistent codes, just frustration. After hooking up my scope, I noticed the 5-volt reference signal to the sensors would occasionally drop out for a split second—a classic sign of an internal PCM failure. We installed one of these pre-programmed modules, performed the security relearn, and the car ran perfectly. The customer saved hundreds by avoiding more guesswork and got a solid fix. That’s the kind of confidence this part provides.
Why do you need my VIN?
Your VIN is essential for us to program the PCM with the correct software for your specific vehicle. This includes engine and transmission calibrations, as well as any factory updates from GM, ensuring optimal performance and a seamless installation.
Is this a plug-and-play part?
Yes, for the most part. Because we pre-program it to your VIN, it eliminates the need for a scan tool for programming. However, you will need to perform a simple key-based security relearn procedure after installation, which takes about 30 minutes and requires no special tools.
Will this fix my ‘No Communication’ issue with my scan tool?
In many cases, yes. A common failure mode for the 2001-2003 Aztek PCM is an internal short that takes down the communication network. If the PCM is the source of the fault, replacing it will restore communication with your diagnostic tools.
Do I need to send my old module back?
No, there is no core charge or need to return your old, faulty module. This simplifies the process for you.
What if I have a different part number on my original module?
This module is a direct replacement for part numbers 12209614, 12202600, and 09360210. As long as your original part number is one of these, and your vehicle is on the compatibility list, this module will work perfectly once programmed.
