Restore Peak Performance to Your Vehicle’s Engine
If your Cadillac XLR is experiencing frustrating issues like a persistent check engine light, poor acceleration, random stalling, or reduced fuel economy, a failing Engine Control Module (ECM) is a likely culprit. As the central computer of your vehicle, the ECM governs everything from fuel injection and ignition timing to transmission shifting. When it fails, the symptoms can be unpredictable and difficult to diagnose. This replacement Engine Control Module, part number 19210737, is the definitive solution to restore your vehicle’s original performance and reliability.
From the Diagnostic Bay
We once had a 2007 Pontiac G6 with a 3.6L V6 come into the shop with an intermittent no-start condition that was driving the owner crazy. They had already replaced the battery and starter. After hours of diagnostics, we traced the issue to a failing power driver within the original ECM. It wasn’t providing a consistent signal to the fuel pump relay. Swapping in a VIN-programmed module like this one solved the problem in minutes. It’s a reminder that the ECM is the true heart of the modern vehicle, and when it falters, the symptoms can appear anywhere.
Why VIN Programming is Essential for Your 2006 XLR Engine Control Module
Unlike simple mechanical parts, a modern ECM is not a one-size-fits-all component. Each module must be specifically calibrated to your vehicle’s unique Vehicle Identification Number (VIN). This process ensures that the computer has the correct software for your engine, transmission, emissions system, and factory-installed options. Our service includes programming this module with the latest GM factory updates using your VIN. This means it arrives at your door ready for installation, eliminating the need for an expensive trip to the dealership for programming. You get a component that is perfectly matched to your vehicle’s specifications, ensuring seamless integration and optimal performance from the moment it’s installed.

- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel efficiency
- ✔ Hard starting or no-start conditions

Frequently Asked Questions
Is this part truly plug-and-play?
Because we program the module to your specific VIN before shipping, it is ready for installation. In most cases, this resolves all programming needs. However, some vehicles may require a simple, key-on security relearn procedure that can be done without special tools. Instructions are available upon request.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email with the information. We cannot ship your part until we receive the VIN.
Will this fix my specific problem?
This ECM will correct any issues directly caused by a faulty engine computer. While the symptoms listed are common indicators of ECM failure, we always recommend a proper diagnosis by a qualified technician to confirm the ECM is the point of failure before ordering.
Is this compatible with other GM vehicles?
Yes, this ECM fits a very wide range of GM vehicles from Buick, Chevrolet, Pontiac, Saturn, Cadillac, and more. The provided fitment list is extensive. As long as your vehicle is on the list and requires one of the interchangeable service numbers, this module will be the correct, programmed part for your application.
What if I order the wrong part?
We strongly encourage you to verify the part number on your existing module and provide your VIN to ensure compatibility. Since each unit is uniquely programmed to a specific vehicle, returns for incorrectly ordered parts may be subject to a restocking fee.
