Is Your Vehicle Running Rough, Stalling, or Showing a Check Engine Light?
If you’re experiencing frustrating engine problems with your 2008 Chevrolet Impala or another compatible GM vehicle, a failing Engine Control Module (ECM) is often the culprit. The ECM is the central computer, the ‘brain’ that manages everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it starts to fail, it can cause a cascade of issues that are difficult to diagnose and can leave your vehicle unreliable or completely inoperable.
Symptoms like erratic idling, poor fuel economy, engine misfires, or a complete no-start condition can all point directly to a faulty computer. You don’t have to put up with poor performance or pay exorbitant dealership prices for a replacement. This direct-fit Engine Control Module, part number 12612384, is the reliable, cost-effective solution you need to get your vehicle back on the road and running smoothly.
From the Diagnostic Bay
I once had a 2008 Sierra 2500 in the shop with a ghost of a problem. The owner complained of intermittent stalling at stoplights and a weird hesitation under acceleration. We checked everything – fuel pump, injectors, spark plugs, sensors – and couldn’t find a consistent fault. The diagnostic scanner would show random communication error codes that would disappear on their own. After hours of chasing wires, we finally hooked up a scope to the ECM’s main communication lines. We saw the signal drop out completely for a split second, just before the engine would stumble. It was a classic case of an internal ECM failure. We installed a VIN-programmed module just like this one, and the truck ran perfectly. It’s a reminder that sometimes the most complex problems come from a single, faulty component.
Common Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is illuminated with various trouble codes.
- ✔ Vehicle refuses to start or has difficulty starting.
- ✔ Poor engine performance, including hesitation, stumbling, or misfiring.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Stalling for no apparent reason, either while driving or at idle.
- ✔ Automatic transmission shifting issues or harsh shifts.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Do I need to do any programming after I receive this module?
No. We program this module to your vehicle’s specific VIN before it ships. In most cases, it is a plug-and-play installation. However, some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools. Instructions are typically included.
Where do I provide my VIN?
You can add your 17-digit VIN in the notes section during checkout or send it to us via email after placing your order. We cannot ship your part until we receive the VIN, as the programming is essential for the part to function correctly.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional replacement part. Each unit undergoes rigorous inspection and testing to ensure it meets strict performance standards before being programmed and shipped.
What if my original part number is not 12612384?
This module is also a direct replacement for part numbers 12622141 and 12617568. If your part number matches one of these, this module will be compatible with your vehicle. Always check the fitment list to be sure.
What is the security relearn procedure?
The security relearn, also known as the key relearn or anti-theft relearn, synchronizes the new ECM with your vehicle’s existing keys and security system. It typically involves a sequence of turning the key to the ‘ON’ and ‘OFF’ positions for specific time intervals. This simple procedure ensures your vehicle will start and run correctly with the new module.
