Is Your GM Vehicle Experiencing Engine Problems?
If your 2016 Chevrolet Camaro, or another compatible GM vehicle like the Silverado, Sierra, or Corvette, is suffering from a persistent Check Engine Light, poor performance, erratic behavior, or a no-start condition, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it falters, the entire vehicle’s performance and reliability are compromised.
The Direct Solution: A VIN-Programmed 2016 Camaro Engine Module
Don’t let a faulty computer keep you off the road or force you into an expensive and time-consuming visit to the dealership. This genuine GM Engine Control Module, part number 12656993, is the definitive solution. We take the hassle out of the replacement process by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it even ships. This ensures that when it arrives, it’s ready for a straightforward installation, loaded with the latest factory software updates from General Motors. This process restores factory performance, fuel efficiency, and emissions compliance.
From the Diagnostic Bay
We had a 2016 Silverado 1500 come in with a bizarre issue: it would randomly lose power and stall, but only after it was fully warmed up. There were no consistent trouble codes, just a few random communication errors that would clear themselves. After hours of chasing wires and testing sensors, we hooked up a scope to the injector driver circuits on the original ECM. We found that the signal for cylinder 3 would degrade and drop out as the module’s internal temperature rose. Swapping in a VIN-programmed module like this one solved the problem instantly. The customer was back on the road the same day, avoiding a costly diagnostic rabbit hole.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or misfiring.
- ✔ A complete no-start or difficult starting condition.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Loss of communication with diagnostic scan tools.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and settings into the new ECM. This includes information about your engine, transmission, emissions equipment, and security system. Without it, the module will not be able to communicate properly with the other computers in your vehicle, leading to a no-start condition. We handle this for you before shipping.
How do I provide my VIN?
After placing your order, simply send us a message with your 17-digit Vehicle Identification Number (VIN). You can find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Is this module difficult to install?
For most DIY mechanics, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in reverse order. Some GM vehicles may require a security relearn procedure afterwards, which can usually be performed by following a simple key-cycling sequence found online.
Will this fix my car’s specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, they can also be caused by other faulty components. Proper vehicle diagnosis is always recommended to confirm the ECM is the point of failure before ordering.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment (OE) component that has been verified to meet or exceed factory specifications. It is programmed with the latest software for your vehicle.
