Is Your 2016 Savana 2500 Sidelined?
A workhorse like the Savana 2500 can’t afford downtime. If you’re dealing with frustrating issues like a no-start condition, erratic engine behavior, poor fuel economy, or a dashboard lit up with warning lights, a failing Engine Control Module (ECM) is often the culprit. This isn’t just an inconvenience; it’s costing you time and money. The ECM is the brain of your van’s engine, and when it fails, it can bring your entire operation to a halt.

Forget expensive dealership visits and the hassle of finding a shop that can program a new module. This ECM, part number 12670335, is the straightforward solution you need. We take care of the most critical step for you: programming. Simply provide us with your vehicle’s VIN during checkout, and our experts will flash the module with the latest, most stable GM factory software specific to your 2016 Savana 2500. It arrives at your door ready for a simple, plug-and-play installation.
Expert Pro Tip: Check This Before You Replace
In my 20+ years in the shop, I’ve seen countless ECMs get replaced unnecessarily. Before you swap the module, do a quick visual inspection of the main engine-to-chassis ground strap. On these GM vans and trucks, it’s often a braided strap near the passenger side of the engine block. Corrosion or a loose connection here can cause voltage drops and mimic nearly every symptom of a bad ECM. A five-minute check with a wire brush can sometimes save you hundreds of dollars.
