Restore Peak Performance to Your GM Vehicle
Is your 2016 Camaro, Silverado, or Corvette suffering from baffling electrical gremlins? A failing Engine Control Module (ECM) is often the culprit behind frustrating issues like a persistent check engine light, rough idling, poor fuel economy, or even a no-start condition. As the ‘brain’ of your vehicle’s engine, the ECM is responsible for thousands of calculations per second, managing everything from fuel injection and spark timing to transmission shifting. When it falters, the symptoms can be widespread and confusing.
This genuine GM Engine Control Module, part number 12672537, is the definitive solution. We take the hassle and high cost out of the repair process. Before we ship the module, our experts will program it with the very latest GM factory software, specifically matched to your vehicle’s VIN. This means you receive a part that is truly plug-and-play, with no need for an expensive trip to the dealership for programming. It’s the most reliable and efficient way to get your vehicle running like new again.
A Technician’s Notebook
I recently had a 2015 Sierra 1500 in the bay that was driving the owner crazy. It had an intermittent hard shift from 1st to 2nd and a random ‘Service StabiliTrak’ message, but no consistent trouble codes. The owner had already replaced the transmission fluid and was considering a costly transmission rebuild. After checking all the wiring and grounds, I hooked up my scope to the CAN bus lines at the ECM. I found signal noise that pointed directly back to the module itself. The internal processors were failing under load. We installed one of these VIN-programmed ECMs, and the truck has been shifting perfectly ever since. It’s a classic example of how a faulty 2016 Camaro Engine Module (or its equivalent in a truck) can manifest as a transmission problem.
Is Your Vehicle Showing These Symptoms?
A failing ECM can cause a variety of issues. If you’re experiencing any of the following, this module is likely the solution you need. Over my 20 years in the shop, these are the most common indicators I’ve seen:
- ✔ Check Engine Light is on with communication codes (like U0100) or internal processor codes (P0601, P0606).
- ✔ Engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or unstable engine idle.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Automatic transmission not shifting correctly or erratically.
- ✔ Unexplained warning lights on the dashboard.
A Straightforward Guide to Installation
Installing your new 2016 Camaro Engine Module is a job most DIYers can handle with basic tools. Following these steps ensures a smooth process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the ECM: On most listed vehicles, the ECM is found in the engine bay, often on the driver’s side front fender or on the firewall. For the Corvette, it’s under the dash on the passenger side cowl.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. There are typically 2-4 bolts holding it in place.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new module until they click securely in place. Reconnect the negative battery terminal.
- Perform Relearn (If Necessary): While this module is pre-programmed, some vehicles may require a security or crank position sensor relearn procedure. This can often be done without special tools (consult a service manual for your specific model) or by any professional mechanic.
