Is your Buick Allure, or another compatible GM vehicle, suffering from perplexing issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance. Don’t let a faulty computer keep you off the road. This replacement Engine Control Module, part number 12607096, is the reliable, professional solution to restore your vehicle’s health and drivability.
Why a VIN-Programmed Allure Engine Control Module is Essential
Modern vehicles are complex systems, and the ECM is the brain of the operation. It controls everything from fuel injection and ignition timing to emissions systems and transmission shifting. Simply installing a used or non-programmed module from another vehicle will not work. Your vehicle’s specific Vehicle Identification Number (VIN) contains critical information about its engine, transmission, and factory-installed options. Our process ensures this module is a perfect match. We flash it with the latest, most stable software updates directly from GM, tailored precisely to your VIN. This eliminates compatibility issues, ensures all systems communicate correctly, and often resolves performance problems that were caused by outdated factory software.
Common Symptoms of a Failing ECM
If you’re experiencing any of the following issues, a failing engine computer could be the culprit. A proper diagnosis is always recommended, but these symptoms are strongly indicative of an ECM problem.
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Engine misfires, hesitation, or rough idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Automatic transmission shifting problems or harsh shifts.
- ✔ Communication errors with diagnostic scan tools.
This module is a direct replacement for a wide array of GM vehicles and is interchangeable with multiple service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. Please verify the extensive fitment list to confirm compatibility with your specific make, model, and engine option. Upon purchase, simply provide us with your VIN, and we’ll handle the programming before shipping it directly to you.
Frequently Asked Questions
Why is providing my VIN so important?
Your vehicle’s VIN is unique and contains specific data about its engine, transmission, emissions systems, and other options. Programming the ECM with your VIN ensures it has the correct software to operate your vehicle exactly as the manufacturer intended, preventing performance issues and compatibility errors.
Is this part difficult to install?
The physical installation is often straightforward, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. However, after installation, your vehicle may require a security relearn procedure or a Crankshaft Variation (CASE) relearn, which requires a compatible professional scan tool. We recommend installation by a qualified technician.
Will this fix my check engine light?
If the check engine light and associated trouble codes are being caused by a faulty ECM, then yes, this replacement part should resolve the issue. It is crucial to have a proper diagnosis performed first to rule out other potential causes like failed sensors or wiring problems.
What is the difference between an ECM and a PCM?
ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. In many modern vehicles, the functions are combined into a single PCM that controls both the engine and the transmission. The terms are often used interchangeably. This part serves as the primary engine/powertrain computer for the vehicles listed.
Do I need to send my old module back?
No core charge or return is required for this purchase. You can keep or responsibly dispose of your old module.
