Is Your 2009 Savana 1500 Running Rough?
If you’re dealing with a persistent check engine light, poor fuel mileage, random stalling, or a complete no-start situation in your work van, the problem often points directly to a failing Engine Control Module (ECM). As a mechanic with over 20 years of experience, I’ve seen countless GM vans and trucks sidelined by faulty engine computers. The ECM is the brain of your vehicle, and when it starts to fail, it can cause a cascade of frustrating and hard-to-diagnose issues.
A customer’s 2009 Savana 1500 work van came in last week with intermittent stalling and a slew of communication codes. After checking the wiring harness for chaffing, which is a common issue on these vans, we isolated the problem to a failing ECM. A replacement like this one, programmed to his VIN, had him back on the road making money the next day without an expensive dealership visit.

Expert Pro Tip from a 20-Year Veteran
Before plugging in your new ECM, take a moment to inspect and clean the main harness connectors. Use a quality electronics cleaner and a small nylon brush to remove any green or white corrosion or packed-in dirt. A poor connection is the number one cause of post-installation issues I see in my shop. A clean, solid connection is critical for the module to function correctly.
Easy Installation for Your 2009 Savana 1500 Engine Computer
Replacing the ECM on your Savana is a straightforward job that you can do in your own driveway. For the Savana and Express vans, the module is located in the left-hand (driver’s side) rear of the engine compartment. Always confirm the location on your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10 minutes for the system to discharge.
- Locate the ECM: Find the module in the LH rear engine compartment. It will have several large electrical connectors attached.
- Disconnect Connectors: Carefully release the locking tabs on each wiring harness connector and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place.
- Reconnect Everything: Firmly plug the wiring harness connectors into the new module until they click, and then re-engage the locking tabs. Reconnect the negative battery terminal.
- Final Step: Your vehicle may require a security relearn procedure, which can typically be done by cycling the key and is detailed in many online forums or service manuals.
