Restore Peak Performance to Your Vehicle’s Powertrain
If you’re dealing with a frustrating check engine light, poor fuel economy, erratic engine behavior, or a no-start condition, the root cause is often a failing Engine Control Module (ECM). As the central computer of your vehicle, a faulty ECM can create a cascade of problems that are difficult to diagnose. This replacement ECM is the definitive solution, arriving at your door fully programmed with the latest GM software updates specifically for your vehicle’s VIN. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
A Technician’s Notebook
I remember a 2006 Saturn ION that came into my bay with a complaint that stumped a couple of other shops. The car would randomly stall at stoplights and sometimes refuse to start for hours. There were no consistent trouble codes, just a few random communication errors that would come and go. After checking all the usual suspects—battery, alternator, grounds—I focused on the ECM. On these GM platforms, I’ve seen internal board failures cause these exact ghost-in-the-machine problems. We swapped in one of our VIN-programmed modules, and the problem vanished instantly. The customer was thrilled to have their reliable daily driver back without the dealership hassle.
Is Your Vehicle Showing These Symptoms?
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel mileage.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication error codes, such as U0100.
- ✔ Internal module memory error codes, like P0601 or P0606.
A Straightforward Guide to Installation
Installing your new 2006 ION Engine Control Module is a direct-fit process that a confident DIYer can handle. Since we program it before shipping, no special computer or dealer visit is required.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the ECM: On the 2006 Saturn ION, the ECM is typically found in the left front of the engine compartment. Consult a repair manual if you have trouble finding it.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new ECM into place and securely reconnect the electrical harnesses. You should hear a ‘click’ as they lock.
- Reconnect and Start: Reconnect the negative battery terminal. The vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes before starting the engine. Your vehicle is now ready to drive.

Do I need to take this to a dealer for programming?
Do I need to take this to a dealer for programming?
No. We program the module to your specific vehicle using the VIN you provide during checkout. It will arrive ready to install, with no additional programming required.
Where do I find my VIN?
Your Vehicle Identification Number (VIN) is a 17-digit code typically found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What if my original part number is different but on the interchange list?
If your original module’s part number is on our interchange list (e.g., 12602044, 12607096), this module is the correct replacement. GM often consolidates part numbers over time, and we supply the correct, updated hardware for your vehicle.
Is this a difficult part to install for a DIYer?
For most vehicles, this is a straightforward replacement. It typically involves disconnecting the battery, unplugging a few connectors, and unbolting the module. As long as you are comfortable working in your engine bay, it is a manageable job.
What happens after I place my order?
After you purchase, you will need to send us your vehicle’s VIN. We cannot ship the module until we have this information to perform the programming service. Once programmed, we will ship it directly to you.
