Is Your Work Van Off the Road? Get it Running Right.
If you rely on your 2016 Chevy Express 2500 for your livelihood, you know that downtime isn’t just an inconvenienceโit’s lost income. When the Engine Control Module (ECM) starts to fail, it can bring your entire operation to a halt. You might be experiencing a frustrating laundry list of problems: the van won’t start, it stalls at intersections, the check engine light is permanently on, and your fuel economy has plummeted. These aren’t just minor annoyances; they’re signs that the brain of your engine is in trouble.
Just last week, a 2016 Express 2500 work van was towed into my shop. The owner, a local contractor, was dealing with intermittent stalling and a dashboard lit up with communication error codes. He was losing money every day the van sat idle. The culprit was a faulty ECM. We replaced it with a precisely programmed unit just like this one, and he was back on the job that same afternoon, no dealership appointment necessary.

Expert Pro Tip: Check for Harness Damage
Before installing your new ECM, take five minutes to inspect the main wiring harness where it runs near the battery tray and along the driver-side fender. On work vans, constant vibration can cause the harness to rub against sharp metal brackets, chafing the insulation and causing intermittent shorts. This is a leading cause of ECM failure that is often overlooked. A quick inspection and some protective wire loom can prevent you from needing to do this job again.
Plug-and-Play Installation: Get Back on the Road Fast
Installing your new 2016 Express 2500 ECM is a straightforward process that you can do with basic hand tools. Because we’ve already done the programming, there are no special computers or dealer tools required.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the ECM: On the Express 2500 van, the ECM is typically found in the engine compartment on the driver’s side, near the firewall or master cylinder.
- Disconnect Connectors: Carefully release the locking tabs and unplug the wiring harness connectors from the old module.
- 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: Plug the wiring harness connectors firmly into the new module until they click, and then reconnect your battery terminal.
- Perform Relearn (If Needed): In some cases, a security or crank-relearn procedure may be required, which can often be done without special tools. Instructions are widely available or we can help guide you.
