Restore Peak Performance to Your Vehicle
Is your vehicle suffering from a persistent check engine light, erratic performance, stalling, or a no-start condition? These are common signs of a failing Engine Control Module (ECM), the central computer responsible for managing your engine’s performance, fuel economy, and emissions. A faulty ECM can cause a cascade of frustrating issues that are often misdiagnosed, leading to costly and unnecessary repairs. This replacement Engine Control Module, part number 12602044, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We once had a 2008 Chevy Trailblazer come into the shop with a problem that stumped two other mechanics. The owner complained of intermittent stalling at stoplights and harsh, unpredictable transmission shifts. No specific codes were stored, just a generic U-code for lost communication. We checked wiring, sensors, and even the transmission module. Finally, on a hunch, we monitored the live data from the ECM and noticed the voltage readings would flicker erratically just before a stall. We installed one of these VIN-programmed modules, and it was like a new truck. The hidden software corruption in the old unit was causing all the chaos. This highlights why getting a module with fresh, correct software is crucial, not just a used one from a junkyard.
Why Choose a VIN-Programmed 2006 XLR Engine Module?
Simply swapping an ECM from another vehicle won’t work. Modern vehicles require the ECM to be programmed with the specific Vehicle Identification Number (VIN) and factory software for your car’s exact configuration, including engine, transmission, and emissions equipment. Our service eliminates the guesswork and the need for expensive dealership programming. When you order from us, we flash the module with the latest official GM software updates using your VIN. This ensures that any factory bugs are corrected and that the module communicates perfectly with all other systems in your vehicle, making for a seamless installation process.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or misfiring
- ✔ Rough or inconsistent idling
- ✔ Poor fuel economy
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Unexplained loss of power and acceleration
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Communication errors with diagnostic scan tools
Guaranteed Compatibility and Simple Installation
This module is a direct replacement for a wide range of General Motors vehicles and is interchangeable with several service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. While the installation is typically straightforward, some vehicles may require a simple security relearn procedure (often called a CASE relearn or anti-theft relearn) after installation, which can be done without specialized tools. We provide clear instructions to guide you through this process. By providing us with your VIN, you ensure you receive a component that is ready to be installed right out of the box, saving you time, money, and the headache of a trip to the dealer.
Frequently Asked Questions
Do I need to program this module?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN at checkout or when we contact you, and the module will arrive with the latest GM software specific to your car.
Where can I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be 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.
Is this part difficult to install?
For most models, the ECM is easily accessible in the engine bay. The physical installation involves disconnecting the battery and swapping the electrical connectors and mounting bolts. Some vehicles may require a simple security relearn procedure afterwards, which we can provide instructions for.
Will this fix my specific problem?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, this part is the solution. It resolves problems related to software corruption, internal circuit failure, and other common ECM-related faults.
What happens after I place my order?
After you complete your purchase, we will contact you to request your vehicle’s VIN. Once we receive it, our technicians will program the module and typically ship it out within one business day.
