Get Your Work Van Back on the Road, Fast.
Is your 2016 GMC Savana 3500 suffering from frustrating and costly electronic issues? A faulty Engine Control Module (ECM) can bring your entire operation to a halt, causing everything from a simple check engine light to a complete no-start condition. This isn’t just an inconvenience; it’s lost time and lost income. Get the definitive solution with this professionally programmed engine computer, designed to restore your van’s reliability and performance without the exorbitant costs and delays of a dealership visit.
Common Symptoms & Your Solution
If your workhorse is experiencing any of the following, a failing ECM is the likely culprit:
- Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0606, U-codes).
- No-Start or Hard-Start Condition where the engine cranks but won’t fire up.
- Rough Idle, Stalling, or Misfires that new spark plugs and coils can’t fix.
- Poor Fuel Economy and a noticeable loss of power.
- Erratic Transmission Shifting or communication errors with the TCM.
This unit is the direct answer to these problems. We take a genuine GM module and flash it with the latest, most stable software calibration from General Motors, specifically matched to your van’s unique Vehicle Identification Number (VIN). This process ensures seamless communication between all vehicle systems, restoring the precise engine management your Savana needs to operate at its peak. When you install our Programmed 2016 Savana 3500 ECM 12670335, you are installing a reliable, fully updated brain for your vehicle’s powertrain.

An Expert’s Note on Software
In modern work vehicles, the software inside the ECM is just as critical as the hardware itself. An ECM with outdated software can cause phantom issues that even new sensors can’t fix. It can lead to inefficient fuel mapping or poor communication with other modules. We ensure your module has the latest GM calibrations available for your VIN, addressing known drivability issues and improving performance from the moment you plug it in. It’s the crucial difference between a van that just ‘runs’ and one that ‘runs right’.
Don’t let a faulty computer dictate your work schedule. This Programmed 2016 Savana 3500 ECM 12670335 is the smart, efficient solution to get your van out of the garage and back to earning its keep. Provide your VIN at checkout, and we’ll handle the rest.
Frequently Asked Questions
What is the process after I place my order?
After you purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program or ship the module without it. Once we have your VIN, our technicians will flash the computer with the correct GM-certified software for your specific vehicle configuration. The unit is then securely packaged and shipped to you.
Is any additional programming required after installation?
In most cases, this ECM is ready to go upon installation. However, some GM vehicles require a simple “Security Relearn” procedure (also known as a Passlock or anti-theft relearn) to sync the new ECM with your keys. This procedure can typically be done yourself in about 30 minutes without any special tools and instructions are readily available online.
How do I find my vehicle’s VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
My old ECM has a different part number. Will this still work?
Yes, this ECM is a direct replacement for a range of part numbers. Please check the compatibility list on this page, which includes numbers like 12668866, 12668994, 12643636, and more. As long as your original part number is on our list, this unit will function correctly once programmed to your VIN.
What does the one-year replacement warranty cover?
Our warranty covers any failure of the ECM unit itself for one full year from the date of purchase. If the module fails due to internal defects, we will provide a replacement unit. The warranty does not cover issues caused by external vehicle faults, improper installation, or physical damage.
