Is your 2016 Savana 2500 work van suddenly unreliable? As a mechanic with over two decades of experience, I know that for a business owner, vehicle downtime means lost income. If you’re dealing with a frustrating no-start condition, rough idling, stalling, or a persistent Check Engine Light, the Engine Control Module (ECM) is often the culprit. This isn’t just a part; it’s the brain of your engine, and when it fails, it can cause a host of perplexing issues that sideline your vehicle.
Don’t let a faulty computer keep you from your work. We offer a dependable and straightforward solution: a replacement Engine Control Module, part number 12692200, that arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical service means you can skip the expensive trip to the dealership for programming. We handle it all for you, loading the latest GM software updates to ensure optimal performance and communication with your van’s other systems. It’s the most efficient way to get your Savana back on the road and earning for you again.
Case Study: A Tricky Diagnosis
I remember a fleet manager bringing in a 2016 Express van—the sister vehicle to the Savana—with a ghost of a problem. The van would randomly refuse to start, but only after it had been running for a while and sat for about 30 minutes. There were no consistent trouble codes, just a general communication loss code (U0100) that would pop up and disappear. We checked the wiring, grounds, and power feeds, and everything seemed fine. After two days of diagnostics, we decided to monitor the ECM’s internal temperature. We found that heat soak was causing an internal failure in the module. Swapping in a VIN-programmed ECM like this one solved the problem instantly. That van went from being the crew’s least favorite to their most reliable, all because of one component.
Common Signs of a Failing Engine Computer
If you’re experiencing any of the following, a failing ECM could be the root cause. A proper diagnosis is always recommended, but these are classic symptoms I’ve seen hundreds of time in the shop:
- ✔ Unexplained Check Engine Light illumination.
- ✔ Stored diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ The engine cranks but refuses to start.
- ✔ Rough or erratic engine idle.
- ✔ Sudden stalling or hesitation during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Transmission shifting problems or failure to communicate with the TCM.

A Straightforward Guide to Installation
Replacing the ECM on your Savana or Express van is a manageable job for a confident DIYer or any professional technician. Always consult a vehicle-specific repair manual, but here is a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On the 2016 Savana/Express vans, the ECM is typically located in the LH rear of the engine compartment.
- Disconnect Connectors: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Never force them. Inspect the connectors for any corrosion or damage.
- 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 ECM in the same location and secure it with the original hardware.
- Reconnect Everything: Plug the electrical connectors firmly back into the new module until they click into place. Reconnect the negative battery terminal.
- Final Steps: Depending on your vehicle’s specific security system, a security relearn procedure may be necessary. This can typically be done without special tools by cycling the key. Turn the ignition on (without starting) for 10-15 minutes, then off for 1 minute, and repeat two more times. Your vehicle should then start and run normally.
