Is Your Work Van Sidelined? Get it Running Right.
There’s nothing more frustrating than a vehicle you depend on suddenly failing. If your Savana 2500 is experiencing bizarre electrical issues, a persistent Check Engine Light, no-start conditions, or erratic engine performance, a faulty Engine Control Module (ECM) is often the culprit. In my 20+ years of diagnostics, I’ve seen how a bad ECM can bring a business to a halt. This isn’t just an inconvenience; it’s lost time and money. This module is the direct, reliable solution to get your workhorse back on the road without the dealership hassle and expense.

Expert Pro Tip: Check This Before You Replace
Before condemning your ECM, take 5 minutes to inspect the main engine-to-chassis ground strap. I’ve seen countless trucks and vans in my shop where a corroded or loose ground strap caused erratic voltage, mimicking a bad computer. It’s usually a thick, braided cable near the engine block. Ensure it’s clean, tight, and free of corrosion at both ends. This simple check can save you from replacing a perfectly good part.
Easy Installation for the DIYer or Professional
Replacing the 2017-2019 Savana 2500 ECM is a straightforward job that can be done with basic hand tools. You’ll typically find the module in the engine compartment on the driver’s side.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10 minutes for the system capacitors to discharge.
- Locate the ECM: Find the existing module. It will have several large wiring harness connectors attached to it.
- Disconnect and Remove: Carefully unplug the wiring harnesses. Most have a locking tab or lever that needs to be released. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Securely reconnect the wiring harnesses, ensuring they click and lock into position.
- Final Steps: Reconnect the negative battery terminal. Your vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Start the engine and verify the Check Engine Light is off.
