Is Your Vehicle Running Poorly?
If your Saturn Aura, Chevy Malibu, or other compatible GM vehicle is experiencing issues like a persistent check engine light, rough idling, stalling, or poor fuel mileage, a failing Powertrain Control Module (PCM) could be the culprit. The PCM is the central computer of your vehicle, responsible for managing the engine, transmission, and dozens of other critical systems. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. Don’t let a faulty computer keep you off the road. This direct-fit replacement PCM is the reliable solution to restore your vehicle’s performance and dependability.
From the Diagnostic Bay
We had a 2010 Chevy Malibu come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that would come and go. The customer had already replaced the spark plugs and an O2 sensor with no luck. Our technician connected the scan tool and found a P0606 internal processor fault code, a classic sign of a failing PCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of these pre-programmed units. After a quick security relearn procedure, the car ran perfectly. The stalling was gone, the light stayed off, and the customer was back on the road with confidence, saving hundreds of dollars.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light with internal processor codes (e.g., P0601, P0606).
- ✔ Unexplained drop in fuel economy.
- ✔ Engine stalling, stumbling, or misfiring.
- ✔ Harsh or erratic transmission shifting.
- ✔ The vehicle cranks but refuses to start.
- ✔ Inconsistent engine performance that gets worse as the vehicle warms up.
- ✔ Failure to pass an emissions test.
The Simple, Reliable Solution: Your Aura PCM Replacement
This isn’t just a replacement part; it’s a complete solution. We take the guesswork and high dealership costs out of the equation. When you order, you provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians then use that VIN to program the module with the latest, most stable software updates directly from GM. This ensures that the PCM is perfectly matched to your vehicle’s specific configuration, including the engine, transmission, and emissions equipment. This process corrects factory bugs and optimizes performance for a seamless installation.
This module is a direct replacement for multiple service numbers, including 12597125, 12612397, 12629019, and 12635902. By programming it to your specific VIN, we ensure compatibility and proper function across a wide range of GM cars, trucks, and vans, such as the Chevy Cobalt, Pontiac G6, Chevy HHR, and GMC Sierra 1500.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), often called the Engine Control Module (ECM), is your vehicle’s main computer. It controls the engine’s fuel injection, ignition timing, emissions systems, and automatic transmission shifting to ensure optimal performance, fuel efficiency, and low emissions.
Do I need to do anything after installing this module?
This module comes pre-programmed to your VIN, making installation straightforward. However, on most GM vehicles, you will need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This procedure syncs the new PCM with your vehicle’s keys and can typically be done in your driveway with no special tools. Instructions are readily available online for your specific model.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM (indicated by codes like P0601, P0602, P0606, etc.), this replacement module will solve the problem. However, if the light is on for other reasons, such as a bad sensor or mechanical issue, those problems will still need to be addressed separately.
What if the service number on my old module is different?
That’s okay. GM uses many different service numbers for the same part. This module is a compatible hardware replacement for all the service numbers listed, including 12597125, 12612397, and 12635902. By programming it with your VIN, we ensure it functions identically to your original module.
