Restore Peak Performance to Your 2006 Isuzu I-350
Is your truck suffering from erratic behavior, poor fuel economy, or a dreaded no-start condition? The Powertrain Control Module (PCM), often called the Electronic Control Module (ECM), is the central computer responsible for managing your engine’s performance, emissions, and transmission functions. When it fails, it can cause a wide range of frustrating and complex issues. This replacement PCM is the definitive solution to get your 2006 Isuzu I-350 running reliably again.
This isn’t just a generic part off a shelf. We provide a fully programmed module tailored specifically to your vehicle. Upon purchase, you will provide us with your vehicle’s VIN. Our technicians will then flash the unit with the latest, most stable software updates directly from GM. This ensures that your new PCM communicates flawlessly with all other modules in your truck, restoring factory performance and efficiency. It arrives at your door ready for a straightforward, plug-and-play installation, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2006 GMC Canyon (which uses this same PCM) come into the shop with a persistent check engine light and a rough idle. The owner had already replaced the spark plugs, ignition coils, and even the mass airflow sensor based on forum advice, but the problem remained. After connecting our diagnostic scanner, we saw multiple communication error codes pointing towards the PCM. Before condemning the module, we performed a ‘wiggle test’ on the main wiring harness connector at the PCM. The engine immediately stalled. A closer inspection revealed two pins inside the connector had backed out slightly, causing a poor connection. After re-seating the pins and securing the connector, all symptoms disappeared. This is a crucial reminder: always verify the wiring and connections to the PCM are secure and clean before replacing the unit itself. A simple physical check can save you hundreds of dollars.
Common Symptoms of a Failing Powertrain Control Module
- ✔ Check Engine Light is illuminated with various trouble codes (DTCs).
- ✔ Engine stalling, misfiring, or running rough.
- ✔ Unexplained drop in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent issues that are difficult to diagnose.

Frequently Asked Questions
What is VIN programming?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the module. This includes information about your engine, transmission, tire size, and other options. We use your Vehicle Identification Number (VIN) to access the correct GM software, ensuring the module works perfectly with your truck right out of the box.
Is this module difficult to install?
Installation is straightforward for someone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it from its mounting location (usually on the firewall or inner fender), and then installing the new one in reverse order. No special tools are usually required.
Will I need to perform any other procedures after installation?
In many cases, no further action is needed. However, some vehicles may require a security relearn or a Crankshaft Position Sensor (CASE) relearn procedure. The security relearn can often be done without special tools, while a CASE relearn may require a capable bi-directional scan tool. These procedures are sometimes necessary to clear certain trouble codes and ensure optimal performance.
How do I provide my VIN after purchase?
After you complete your purchase, we will send you an email with instructions on how to reply with your 17-digit VIN. You can also add it as a note during the checkout process. We cannot ship your order until we receive and validate your VIN.
What if my original part number is not on your list?
If your part number is not listed, please contact us with your vehicle’s VIN and the part number from your original module. We can verify compatibility and ensure you receive the correct component for your vehicle.
