Is Your Chevrolet Camaro Experiencing Engine Problems?
The Electronic Control Module (ECM), often called the engine computer, is the central command center for your vehicle’s engine. It manages critical functions like fuel injection, ignition timing, and emissions systems to ensure optimal performance, fuel economy, and reliability. When the ECM in your 2013-2015 Camaro begins to fail, it can lead to a cascade of frustrating and potentially damaging issues, from a simple check engine light to a car that won’t start at all.
Expert Pro Tip: Before replacing your ECM, always perform a thorough check of the vehicle’s battery, charging system, and all main power and ground connections to the module. A corroded ground wire or a weak battery can mimic the symptoms of a failed ECM, leading to a costly misdiagnosis. Use a multimeter to verify you have stable voltage and solid ground paths at the ECM connector.
Symptoms of a Failing GM Engine Computer
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Misfires or rough idling.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
- ✔ Intermittent electrical issues or warning lights on the dashboard.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.

Frequently Asked Questions
What is an ECM and what does it do?
The ECM, or Electronic Control Module, is your car’s main computer for the engine. It takes data from sensors all over the engine (like oxygen sensors and crank position sensors) and uses that information to control the fuel injectors, spark plugs, and other outputs to make the engine run efficiently and cleanly.
Is this ECM ready to install when I receive it?
Yes! This module is programmed to your vehicle’s specific VIN before we ship it. This means it is ready for installation upon arrival. In most cases, this makes the process plug-and-play, getting you back on the road quickly.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add this 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 to program it.
My old ECM has a different part number. Will this still work?
Yes, this ECM (12655007) is a direct, updated replacement for several older part numbers, including 12653998, 12633555, and 12644446. As long as your vehicle is on our compatibility list, this module will function correctly as the proper superseding part.
Will I need to do anything else after installing the ECM?
In some GM vehicles, you may need to perform a security relearn procedure (often called Passlock or Passkey) or a Crankshaft Variation (CASE) relearn. These are simple procedures that can often be done without special tools and ensure the ECM communicates properly with the anti-theft system and crankshaft position sensor. Instructions for these procedures are widely available online for your specific model.
