Is Your GM Truck or SUV Experiencing Mysterious Electrical Problems?
If your Silverado, Suburban, Tahoe, or other GM vehicle is suffering from issues like erratic engine behavior, poor fuel economy, harsh transmission shifts, or even a frustrating no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer, the PCM governs everything from fuel injection and ignition timing to transmission operation. When it begins to fail, it can create a cascade of confusing and costly problems that are difficult to diagnose.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) with communication-related fault codes (e.g., U-codes).
- ✔ Engine stalling, stumbling, or running rough for no apparent reason.
- ✔ Abrupt, harsh, or delayed transmission shifting.
- ✔ A complete no-start condition where the engine cranks but will not fire up.
- ✔ Noticeable decrease in fuel efficiency and overall engine performance.
- ✔ Malfunctions with other electronic systems, as the PCM communicates with multiple modules.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
No. We program the module to your vehicle’s specific VIN before it ships. It arrives at your door ready to be installed, saving you time and money.
Where do I provide my vehicle’s VIN?
After you complete your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your PCM without this information.
What is a security relearn, and is it difficult?
A security relearn syncs the new PCM with your vehicle’s anti-theft system. It’s a simple procedure that usually involves turning the ignition key to the ‘ON’ position for about 10-15 minutes, then off, and repeating two more times. Instructions are readily available online for your specific model.
How can I be sure this fits my truck?
This PCM fits a vast number of 2003-2007 GM trucks and SUVs. The best way to confirm is to match the service number on your original module to one of the numbers listed (89017734, 12582605, etc.). Providing us with your VIN guarantees we send you a perfectly matched and programmed part.
What tools are required for installation?
You’ll typically only need basic hand tools, such as a socket and ratchet set, to remove the battery and access the PCM mounting bracket. No specialized electronic tools are needed for the physical installation.
