Is Your 2011 Chevrolet Cruze Running Rough?
If your 2011 Chevy Cruze is experiencing frustrating issues like stalling, poor acceleration, a persistent check engine light, or even a no-start condition, 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 control. When it starts to fail, the symptoms can be unpredictable and difficult to diagnose, leaving you stranded and facing a costly repair bill from the dealership.
This replacement ECM is the definitive solution to get your vehicle running reliably again. It’s not just a part; it’s a complete, pre-programmed component designed for a seamless installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance, eliminating the need for expensive dealership programming.
From the Diagnostic Bay
We had a 2011 Cruze 1.4L come into the shop with a ghost of a problem. The owner complained of random stalling at stoplights and an intermittent check engine light that would come and go. We checked for vacuum leaks, tested sensors, and cleaned the throttle body, but the problem persisted. The codes were all over the place—misfires, communication errors, and a generic processor fault code (P0606). After hours of chasing our tails, we focused on the ECM. On the surface, it looked fine. But we knew from experience that internal circuit board failures can cause these exact unpredictable symptoms. We installed a VIN-programmed ECM, performed the security relearn, and the car ran perfectly. The owner was thrilled to have their reliable daily driver back without the stress of wondering when it would stall next. This is why a quality, correctly programmed module is non-negotiable.

Frequently Asked Questions
Is this ECM ready to install right out of the box?
Yes, this unit comes fully programmed to your vehicle’s VIN with the latest GM software updates. After installation, you may need to perform a simple security/anti-theft relearn procedure, which can typically be done in your driveway and does not require a trip to the dealer.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have your VIN.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (indicated by codes like P0601, P0606, etc.), then this replacement part will solve the problem. However, if the light is on due to other issues like a bad sensor or a mechanical problem, those issues will need to be addressed separately.
Where is the ECM located on my 2011 Chevy Cruze?
On the 2011 Chevrolet Cruze, as well as the compatible Sierra and Silverado models, the Electronic Control Module is typically located in the engine compartment on the driver’s side (LH front).
What part numbers does this module replace?
This ECM is a direct replacement for part numbers 12616532, 12642100, and 12656958. Please verify one of these numbers is on your original module to ensure compatibility.
