Restore Your Vehicle’s Reliability and Performance
Is your 1999-2000 LeSabre, Bonneville, or Grand Prix suffering from frustrating and unpredictable issues? A failing Engine Control Module (ECM), also known as a Powertrain Control Module (PCM), is often the hidden culprit behind check engine lights, poor performance, and even no-start conditions. This isn’t just a replacement part; it’s a complete, pre-programmed solution designed to get your trusted GM vehicle back on the road with the reliability you depend on. We take a genuine, tested OEM unit and flash it with the latest official GM software, tailored specifically to your vehicle’s VIN. This eliminates the need for expensive dealership programming, saving you time, money, and headaches.

Expert Insight: Why Pre-Programming is Non-Negotiable
As a technician, I’ve seen countless DIYers get stuck after installing a used computer. They swap the part, but the car still won’t start or run correctly because of the anti-theft system (PassLock/PassKey). The module must be electronically ‘introduced’ to the vehicle. Our pre-programming service handles this critical step for you. We flash the module with your VIN, which syncs it with your car’s systems. This professional-level service is the secret to turning a potentially complex electronic repair into a straightforward, manageable job you can do at home.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Will I need to do anything after installation?
In many cases, the vehicle will start and run immediately. However, some GM vehicles of this era may require a simple, no-tool security relearn procedure that takes about 30 minutes to perform. We can provide instructions for this common procedure upon request.
Is this a brand-new part?
No, this is a genuine OEM computer that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure it is fully functional before being programmed and shipped. This allows us to provide a reliable, compatible part at an excellent value.
Where is this computer located on my vehicle?
The location varies slightly by model, but on most of the listed vehicles (LeSabre, Bonneville, Impala, Century), the ECM is located in the engine compartment, typically inside the air filter box assembly for protection and cooling.
What if this doesn’t fix my problem?
While this Programmed 09361735 ECM PCM is the solution for the symptoms listed, proper vehicle diagnostics are key. We recommend confirming your diagnosis before ordering. If the part is found to be defective, it is covered by our one-year replacement policy.
