Restore Peak Performance to Your GM Vehicle
Is your Camaro, Silverado, or Corvette running rough, stalling unexpectedly, or refusing to start? A faulty Engine Control Module (ECM) is often the culprit behind these frustrating and complex issues. As the brain of your engine, the ECM governs everything from fuel injection and ignition timing to transmission shifting. When it fails, performance suffers dramatically. This isn’t just an inconvenience; it can be a serious safety concern. For over 20 years, I’ve seen countless vehicles sidelined by ECM failure, leaving owners stranded and facing expensive dealership repair bills.
We offer a reliable and straightforward solution. This genuine GM Engine Control Module, part number 12673195, is the definitive fix for your vehicle’s electronic woes. The best part? We handle the complex programming for you. Simply provide your vehicle’s VIN during checkout, and our experts will flash the module with the latest, most stable GM software specific to your car or truck. It arrives at your door ready for installation, saving you hundreds of dollars and the hassle of a trip to the dealership for programming.
From the Diagnostic Bay: The Intermittent Stall Mystery
A customer brought in a 2015 Sierra 1500 that would stall randomly at stoplights—no codes, no warning. We checked fuel pressure, sensors, and wiring, but everything seemed fine. The issue was so intermittent it was nearly impossible to replicate. From experience, I know that heat soak can cause internal ECM components to fail unpredictably. We connected a data logger and finally caught a drop in processor voltage right before a stall. We swapped in one of our pre-programmed ECMs, and the problem was solved instantly. The customer was back on the road the same day, avoiding a costly, multi-day diagnostic ordeal at the dealer.
Is Your Vehicle Showing These Symptoms?
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your engine’s computer needs attention. A faulty 2016 Camaro Engine Control Module can trigger a wide range of issues across many compatible GM vehicles.
- ✔ Check Engine Light is on with codes like P0601, P0606, or U0100
- ✔ Engine cranks but refuses to start
- ✔ Unexplained stalling or rough idling
- ✔ Significant drop in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Misfires or loss of power during acceleration
- ✔ Failure to pass an emissions test
A Straightforward Guide to Installation
Replacing the ECM is a task many DIY enthusiasts can handle with basic tools. Our pre-programmed module eliminates the most difficult step. Follow this general guide for a successful installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On most listed vehicles (like the Silverado/Sierra or Camaro), the ECM is found in the engine compartment, typically on the driver’s side front. On others, like the Corvette, it may be under the dash on the passenger’s side. Refer to your owner’s manual for the exact location.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old ECM. These often have locking tabs that need to be released. Do not force them.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will need it for the new module.
- Install the New ECM: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses into the new module until they click into place. Reconnect the negative battery terminal.
- Perform Relearn (If Necessary): While our programming handles the heavy lifting, some vehicles require a security or crank-sensor relearn procedure. This can often be done without special tools (e.g., turning the key to ‘On’ for 10-15 minutes). Check your service manual for any vehicle-specific steps.
