Is Your 2004 Savana 2500 Running Rough, Stalling, or Throwing Codes?
As a mechanic with over two decades of experience, I’ve seen countless work vans like the Savana 2500 come into the shop with frustrating, intermittent problems. Symptoms like a persistent check engine light, poor fuel mileage, erratic shifting, or a no-start condition can often be traced back to one component: a failing Engine Control Module (ECM), also known as a Powertrain Control Module (PCM). The constant heat and vibration in the engine bay eventually take their toll on these vital electronics.
This isn’t just a part; it’s the brain of your vehicle’s engine, controlling everything from fuel injection to ignition timing. When it fails, your reliable workhorse becomes a major headache. This replacement module is the direct, hassle-free solution to get your van back on the road and earning its keep.
Real-World Diagnosis: “A customer’s 2004 Savana 2500 came in last week with these exact symptomsโit would run fine for a day, then refuse to start the next morning. We checked all the usual suspects: battery, grounds, fuel pump. The scanner showed a slew of communication error codes. After swapping in a known-good PCM, the van fired right up and ran perfectly. The original module’s internal circuits had failed from years of heat cycles, a very common issue on these work vans.”

Plug-and-Play Installation Guide for your 2004 Savana 2500 Engine Control Module
Installing your new ECM is a straightforward process you can do with basic hand tools. On the 2004 Savana 2500 Van, the module is located in the left-hand (driver’s side) rear of the engine compartment.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to ensure the system is fully discharged.
- Locate the Module: Find the ECM in the rear driver’s side of the engine bay. It’s a silver metal box with several large electrical connectors.
- Disconnect Wiring: Carefully release the locking tabs on each electrical connector and pull them straight out from the module. Never force them. Inspect the connectors for any corrosion or bent pins.
- Remove the Old Module: Unbolt the mounting hardware holding the old ECM in place and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed module in the same location and secure it with the original hardware.
- Reconnect and Secure: Firmly plug the electrical connectors into the new module until they click and lock into place. Reconnect the negative battery terminal.
- Final Step: Your vehicle may need to complete a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for the specific procedure for your van.
