Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable software updates directly from GM. This ensures perfect communication between the module and your van’s specific systems, restoring the smooth operation and reliability you depend on.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’08 Savana 2500 with a 6.0L engine. The complaint was intermittent stalling at stoplights and a random P0606 (ECM/PCM Processor Fault) code that would come and go. We checked all the basics—battery, grounds, and wiring harnesses—and everything looked solid. The intermittent nature of the problem pointed directly to an internal failure in the ECM. Instead of a costly new unit from the dealer, he opted for one of our pre-programmed modules. The swap took less than 30 minutes in the bay. After the install and a quick security relearn, the van ran perfectly. He’s been back for oil changes since, with zero repeat issues. This part saved him significant downtime and over $700 compared to the dealership quote.
Is Your Van Exhibiting These Common ECM Failure Signs?
A failing ECM can manifest in various ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Check Engine Light is illuminated with communication-related codes (e.g., U0100, P0601, P0606).
- ✔ The engine cranks but refuses to start.
- ✔ Severe drop in fuel efficiency for no apparent reason.
- ✔ Rough or unstable engine idle.
- ✔ The vehicle stalls unexpectedly while driving or when coming to a stop.
- ✔ Automatic transmission shifts harshly or at the wrong times.
- ✔ Noticeable loss of power and poor acceleration.
A Straightforward Guide to Installation
Installing your new 2008 Savana 2500 Engine Control Module is a manageable job for a DIYer or any professional mechanic. With our pre-programming service, you eliminate the most complex step.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and secure it away from the post to prevent accidental reconnection.
- Locate the ECM: On the 2008 Savana Van, the ECM is typically found in the engine compartment on the driver’s side, near the rear of the engine bay.
- Disconnect the Module: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. There may be several connectors, so take your time to avoid damaging the pins or wiring.
- Remove the Old ECM: Unbolt the module from its mounting bracket. Keep the mounting hardware as you will need it for the new unit.
- Install the New ECM: Mount your new, pre-programmed module onto the bracket and secure it with the original hardware.
- Reconnect Everything: Firmly plug the electrical connectors back into the new ECM until they click into place. Reconnect the negative battery terminal.
- Perform Security Relearn: In many cases, you will need to perform a simple key-cycle security relearn procedure to sync the new ECM with your vehicle’s anti-theft system. This procedure can typically be found online or in your owner’s manual and requires no special tools.

Frequently Asked Questions
Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the process where we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM-approved software onto the ECM. This ensures the module works perfectly with your specific engine, transmission, and options, just like the original factory unit.
Is any additional programming required after I install it?
No dealership programming is needed. The only step you may need to perform is a simple security relearn procedure, which involves a series of key turns. This syncs the module to your keys and can be done in your driveway without any special tools.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function.
How can I be sure this is the right part for my van?
The best way is to match the part number from your existing module. Look for 12612384, 12622141, or 12617568 on the sticker of your current ECM. You can also use the compatibility list provided as a guide.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (common codes include P0601, P0606, U0100), then this replacement 2008 Savana 2500 Engine Control Module is the correct fix. However, it’s always best to have the codes professionally diagnosed to rule out other issues like sensors or wiring.
