Restore Peak Performance to Your Vehicle with a VIN-Programmed Engine Control Module
Is your vehicle suffering from frustrating and difficult-to-diagnose issues like a persistent Check Engine Light, intermittent stalling, poor fuel economy, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s performance. Don’t let a faulty computer keep you off the road. This direct-fit replacement Engine Control Module, service part number 12630457, is the definitive solution to restore your vehicle’s reliability and drivability.
What sets this module apart is our professional programming service. Before this part ever ships, we flash it with the latest official GM software updates, precisely matched to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures seamless integration with your car’s existing systems, eliminating the need for an expensive trip to the dealership for programming. You receive a component that is ready for installation right out of the box, saving you time, money, and hassle.
From the Diagnostic Bay
We had a 2008 Chevy Impala come into the shop with a problem that was driving the owner crazy. It would randomly stall at stoplights, but never consistently, and it threw a confusing mix of communication and sensor codes. The owner had already replaced the throttle body and a few sensors with no luck. After hours of tracing wires and checking grounds, we hooked up our scope to the ECM’s 5-volt reference circuit and saw the voltage intermittently drop out. The internal voltage regulator in the original ECM was failing. We installed one of these VIN-programmed modules, performed the quick security relearn, and the car ran perfectly. It’s a great reminder that when electronics start behaving erratically, the central computer is often the culprit.
Is a Failing ECM the Source of Your Problems?
The ECM is the brain of your engine, controlling everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it begins to fail, the symptoms can be widespread and confusing. If you’re experiencing any of the following, a faulty ECM could be to blame.
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Unexplained engine stalling or hesitation, especially when warm.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough idling or engine misfires.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The engine cranks but refuses to start.
- ✔ Inability for scan tools to communicate with the module.

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and we will load the latest GM software specific to your car. It arrives ready to install.
What is the VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. 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.
What is a “security relearn” and is it difficult?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM with your vehicle’s security system. For most GM vehicles of this era, it involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating this cycle three times. Specific instructions for your vehicle can be easily found online or in a service manual.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators of ECM failure, they can also be caused by other issues like bad wiring or faulty sensors. A thorough diagnosis by a qualified technician is the best way to confirm the ECM is the root cause before ordering a replacement.
Is this part compatible with my vehicle if the part number isn’t an exact match?
Yes, this ECM is a replacement for several interchangeable service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, and 19210737. As long as your vehicle is on our compatibility list, this module will function correctly once programmed to your VIN.
