Is Your GMC Envoy Experiencing Engine Problems?
n
If your 2003, 2004, or 2005 GMC Envoy, Chevy Trailblazer, or other compatible GM SUV is suffering from perplexing issues like stalling, erratic shifting, a persistent Check Engine Light, or a complete no-start condition, the culprit is often a failing Powertrain Control Module (PCM). The PCM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.

From the Diagnostic Bay
n
We once had a 2004 Trailblazer in the shop that had been to three other mechanics. The owner had replaced the spark plugs, ignition coils, and even the fuel pump, but it still had a random, intermittent misfire and would occasionally refuse to start. After hours of chasing wires, we finally hooked up a scope to the PCM outputs and saw the injector driver for cylinder 3 was dropping out intermittently. A new, properly programmed PCM fixed the issue instantly. The owner had spent over a thousand dollars on parts he didn’t need, when the core problem was the engine’s brain itself. This highlights the importance of correctly identifying a faulty module.

Don’t let a faulty computer keep your reliable SUV off the road. This replacement Powertrain Control Module is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures that all factory settings, engine parameters, and security information are a perfect match for your Envoy, Trailblazer, Rainier, Bravada, Ascender, or 9-7X. By providing us with your VIN at checkout, you receive a module that is ready for installation, loaded with the latest GM-certified software updates to optimize performance and efficiency.
nn
This module is a direct replacement for multiple OEM part numbers, including 12573576, 12574976, 12577955, 12584593, 16255757, and 19210065. It is meticulously inspected and tested to ensure it meets or exceeds original equipment standards for function and durability. The process is simple: you order, provide your VIN, and we ship a module that is programmed and ready to get your vehicle running right again.

Installation and Security Relearn
n
Installation is straightforward for any competent DIY mechanic or professional technician. After installing the module, you will need to perform a simple security relearn procedure, often called a “CASE Relearn” or “Passlock Relearn.” This procedure syncs the new PCM with your vehicle’s anti-theft system and can typically be done without special tools, often involving a sequence of key turns. Instructions for this procedure are widely available and ensure your vehicle starts and runs correctly with its new brain.

Frequently Asked Questions
What is the process after I purchase this PCM?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this VIN to load the exact, correct GM software and calibrations onto the module before we ship it to you.
Is this part truly plug-and-play?
It is pre-programmed to your VIN, which handles 99% of the setup. However, like any PCM replacement on these GM vehicles, you will need to perform a security relearn procedure to sync the module with your vehicle’s anti-theft system. This is a simple procedure that usually takes about 30 minutes.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty PCM. While the symptoms listed are common indicators of PCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the PCM is the root cause of your problem before ordering.
Which vehicles does this PCM fit?
This PCM fits a wide range of 2003-2006 GM SUVs with the 4.2L inline-6 engine, including the GMC Envoy, Chevy Trailblazer, Oldsmobile Bravada, Buick Rainier, Isuzu Ascender, and Saab 9-7X. Please verify your original part number against our compatible list to ensure a perfect match.
Do I need to send my old PCM back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
