Restore Peak Performance to Your Vehicle
Is your Chevrolet Uplander, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs of 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 control. When it falters, the entire system’s performance and reliability are compromised. This direct replacement Engine Control Module, part number 12630457, is the definitive solution to get your vehicle running like new again.

From the Diagnostic Bay
We had a 2006 Chevy Uplander in the shop that was driving the owner crazy. It had an intermittent stalling problem that would only happen after it was fully warmed up, and it never stored a trouble code. We checked fuel pressure, sensors, and wiring harnesses, but everything tested fine. On a hunch, we connected a scope to the ECM’s power and ground circuits and noticed voltage fluctuations when the engine bay got hot. We swapped in a VIN-programmed module like this one, and the problem was solved instantly. The internal circuits of the old ECM were failing under heat, a common issue that a simple code reader won’t catch.
Is Your Vehicle Showing Signs of ECM Failure?
- ✔ Persistent Check Engine Light (CEL) with various codes or no codes at all.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough or erratic idling.
- ✔ Hard starting or no-start conditions.
- ✔ Unexplained loss of power.
- ✔ Problems with automatic transmission shifting.

Frequently Asked Questions
Do I need to program this module after I receive it?
No. This module comes fully programmed to your vehicle’s specific VIN before it is shipped. It is designed to be a plug-and-play solution, saving you a costly trip to the dealership.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email. We cannot ship the module until we have your VIN to ensure correct programming.
What is the difference between an ECM, PCM, and ECU?
These terms are often used interchangeably. ECM stands for Engine Control Module, ECU for Electronic Control Unit, and PCM for Powertrain Control Module. For most modern vehicles, they refer to the same computer that controls the engine and, in the case of a PCM, the transmission as well. This part serves as your vehicle’s main engine computer.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to properly diagnose the problem first. After installation, all diagnostic trouble codes (DTCs) should be cleared with a scan tool.
Are any other procedures required after installation?
In some GM vehicles, a security relearn or a Case Crankshaft Position Variation Relearn procedure may be necessary. The security relearn can often be done without special tools, while the crankshaft relearn requires a compatible bi-directional scan tool. These are standard procedures when replacing an ECM on these vehicles.
