Restore Peak Performance to Your 2008 Express Van
Is your 2008 Chevy Express 2500 van running rough, stalling unexpectedly, or displaying a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine, transmission, and emissions systems. A faulty ECM can lead to a cascade of frustrating and difficult-to-diagnose issues, leaving your reliable workhorse parked on the sidelines. This replacement Engine Control Module, part number 12622141, is the definitive solution to get your van back on the road and working as hard as you do.
Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this module arrives at your door ready for installation. We handle the critical programming for you. Simply provide us with your vehicle’s VIN (Vehicle Identification Number) during checkout, and our technicians will flash the module with the latest, most stable GM-approved software specific to your van’s configuration. This ensures seamless communication between the new ECM and all other onboard systems, restoring the original performance and efficiency you depend on.
We recently had a customer with a 2008 Express 2500 that had been to three different shops. The van had an intermittent no-start condition and would occasionally stall at idle. They had already replaced the crank sensor, cam sensor, and fuel pump based on various generic trouble codes. The problem persisted. When it finally got to our bay, we noticed communication dropouts with the ECM on our high-level scan tool. The root cause wasn’t a faulty sensor; it was the main computer failing under certain conditions. We installed a VIN-programmed module just like this one, performed the security relearn, and the van fired up perfectly every time. It’s a powerful reminder that addressing the core problem saves a lot of time and money spent chasing symptoms.
Is Your Van Showing Signs of ECM Failure?
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your engine’s computer is the culprit. This programmed 2008 Express 2500 ECM is designed to resolve these exact issues:
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Unexplained drop in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start or intermittent starting problems
- ✔ Misfire codes (e.g., P0300) even after replacing plugs and coils
- ✔ Loss of communication with diagnostic scan tools
- ✔ Failure to pass emissions testing

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact GM-specified software for your van’s engine, transmission, and options. This ensures the module works perfectly out of the box and communicates correctly with all other systems, preventing compatibility issues.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. The most important step after installation is the security relearn procedure.
Will I need to do anything after installation?
Yes. After installing the new ECM, you will need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This procedure syncs the new module with your vehicle’s anti-theft system and can usually be done without special tools. Instructions are widely available online or in service manuals.
How can I be sure my old ECM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis is best. This often involves a professional technician using a scan tool to check for communication errors with the ECM (like a U0100 code) and ruling out other potential causes like wiring or sensor faults.
What part numbers does this module replace?
This module is a direct replacement for GM part numbers 12622141, 12612384, and 12617568. If your original module has one of these numbers, this part is a compatible replacement.
