Is Your Chevrolet Trax Experiencing Frustrating Engine Problems?
If you’re dealing with a persistent Check Engine Light, rough idling, stalling, or a no-start condition in your 2013-2016 Trax, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions controls. When it fails, it can cause a cascade of issues that make your vehicle unreliable and unsafe to drive. In my 20+ years as a technician, I’ve seen how a faulty ECM can mimic a dozen other problems, leading to expensive and unnecessary repairs.
“A customer’s 2015 Trax came in last week with a persistent P0606 code (ECM Processor Fault) and intermittent stalling during acceleration. After confirming all power and ground circuits to the module were solid, we knew the ECM itself had failed internally. Swapping in a pre-programmed unit like this one had them back on the road in under an hour, completely avoiding a costly tow and lengthy wait at the dealership.”

Simple Plug-and-Play Installation
You can get your Trax back in top shape with basic hand tools. Follow these simple steps for a successful installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down.
- Locate the ECM: On the 2013-2016 Trax, the ECM is typically located in the engine compartment, often near the battery or firewall.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small screwdriver to release the locking tabs if necessary. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed ECM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Reconnect Battery: Reattach the negative battery terminal. Your vehicle is now ready to start. The computer will perform a self-learning process over the first 50-100 miles of driving.
Expert Pro Tip: Check for the Root Cause
Before installing your new ECM, take a moment to inspect the ignition coils and their wiring harnesses. A failing or shorted ignition coil is a very common reason for the original ECM’s driver circuit to fail. Simply replacing the module without addressing the underlying issue can cause the new ECM to fail prematurely. It’s a quick check that can save you from a repeat repair.
