Is Your GM Vehicle Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, erratic engine behavior, stalling, or a complete no-start condition in your 2006-2007 Saturn ION, Chevy Cobalt, or 2006 Malibu, 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. When it malfunctions, it can lead to a cascade of problems that are often misdiagnosed, costing you time and money on unnecessary repairs.
The Reliable Solution for Your Engine Problems
This is a genuine, road-tested used GM Engine Control Module, compatible with part numbers 12597520, 12579132, and 12615197. We take the guesswork and hassle out of the replacement process. Unlike buying a module from a junkyard that requires expensive dealer programming, we flash this ECM with the latest GM-certified software specifically for your vehicle’s Vehicle Identification Number (VIN) before we ship it. This means it arrives at your door ready for installation, saving you a trip to the dealership and costly programming fees. Get your vehicle back to factory-spec performance and reliability.
From the Diagnostic Bay
We recently had a 2007 Cobalt SS with the 2.0L supercharged engine come into the shop. The owner had already replaced the MAP sensor, throttle body, and spark plugs chasing a persistent P0606 (ECM Processor Fault) code and intermittent stalling. The car would run fine for a few days, then suddenly lose power. After confirming all sensor inputs were correct, we identified the ECM as the culprit. A faulty processor was causing it to lose communication intermittently. We installed one of our VIN-programmed modules, performed the security relearn, and the car has been running perfectly ever since. It’s a classic case where targeting the ‘brain’ first saved further diagnostic headaches.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light (CEL) is on with codes like P0601, P0602, P0606, or U-series communication codes.
- ✔ Engine cranks but refuses to start.
- ✔ Stalling for no apparent reason, either while driving or at idle.
- ✔ Noticeable decrease in fuel economy.
- ✔ Poor engine performance, hesitation, or misfiring.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Inaccurate or non-functional dashboard gauges.
Why Choose Our 2006-2007 Saturn ION ECM?
This isn’t just a used part; it’s a complete, ready-to-install solution. We handle the most critical step – the programming – so you don’t have to. By providing us with your VIN at checkout, you ensure that the module you receive is a perfect software match for your vehicle’s specific configuration, including its engine, transmission, and emissions equipment. This direct-fit, pre-programmed module is the most efficient and cost-effective way to restore your vehicle’s performance and eliminate those troublesome electronic faults.
Installation Process
After receiving your VIN-programmed module, physical installation is straightforward. However, please be aware that on most GM vehicles of this era, you will need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This procedure syncs the new ECM with your vehicle’s existing anti-theft system and keys. It typically takes about 30 minutes and can be done without special tools. Instructions are widely available online or in service manuals. In some cases, a Crankshaft Variation (CASE) relearn may be required, which necessitates a capable scan tool.

Frequently Asked Questions
Do I need to get this ECM programmed?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation and the security relearn procedure.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can typically find it on a plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a new part?
No, this is a high-quality, tested used OEM part sourced from a salvaged vehicle. Each unit is inspected and verified to be fully functional before being programmed and shipped.
Will this definitely fix my car’s problem?
This module will correct any issues directly caused by a faulty ECM. However, it’s crucial that your vehicle has been properly diagnosed. If your problem is caused by a bad sensor, wiring issue, or mechanical failure, replacing the ECM will not resolve it.
What is a security relearn procedure?
It’s a process that allows your vehicle’s anti-theft system to recognize the replacement ECM. It usually involves a sequence of turning the key on and off for set periods of time. The procedure is simple and does not require special tools.
Which part number will I receive?
You will receive one of the fully interchangeable part numbers listed: 12597520, 12579132, or 12615197. All are OEM parts and function identically once programmed for your vehicle.
