This is the simple, reliable, and direct solution to restore your car’s performance and your peace of mind. #### Common Symptoms & Your Solution A failing engine computer can manifest in numerous ways, leaving you stranded and facing a confusing diagnosis. This module is the definitive solution for problems including: - Check Engine Light with communication-related DTCs (e.g., P0601, P0606) - Engine stalling or cutting out while driving - Harsh or erratic shifting - Complete failure to start - Poor engine performance and reduced gas mileage - Communication issues with diagnostic scan tools By replacing your old unit with this expertly programmed **2006-2009 Buick Allure 3.8L PCM**, you are installing a fresh, correctly calibrated brain into your vehicle, directly addressing the root cause of these electrical gremlins. #### Features & Benefits - ✔ **VIN-Specific Programming:** We flash this module with the latest GM-certified software using your vehicle’s unique VIN.

A generic, non-VIN matched computer can cause more problems than it solves, from transmission damage to immobilizer lockouts. That’s why we insist on programming each **2006-2009 Buick Allure 3.8L PCM** to your specific VIN. This process ensures all the unique calibrations for your car’s options and security systems are correctly loaded, making the installation process smooth and the final repair reliable. It’s the difference between a quick fix and a lasting solution. #### Frequently Asked Questions **How do I provide my Vehicle Identification Number (VIN)?** After placing your order, simply send us a message with your 17-digit VIN. We cannot program and ship your module without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on your insurance card, or on the driver’s side door jamb sticker. **Do I need to do anything after installing the PCM?** Yes. While the main engine programming is complete, you will need to perform a security relearn procedure (also known as a CASE relearn or anti-theft relearn). This process syncs the new PCM with your vehicle’s existing keys and anti-theft system. It is a simple procedure that typically takes 10-30 minutes and does not require special tools. Instructions can be easily found online for your specific model. **Will this fit my Pontiac Grand Prix even though the keyword says Buick Allure?** Yes! As long as your vehicle is one of the models listed in the fitment guide (Allure, LaCrosse, Lucerne, Grand Prix) with the 3.8L engine and a matching part number, this module is the correct part for you. We use a primary model like the Buick Allure for the focus of the listing, but the **2006-2009 Buick Allure 3.8L PCM** is functionally identical for all compatible vehicles. **Are these brand new modules?** These are high-quality, tested, and inspected original equipment modules that have been professionally programmed with the latest software for your vehicle. They are guaranteed to function correctly and meet or exceed original factory specifications. **What if my original part number is slightly different?** This module replaces several part numbers, including **12600930**, **12616866**, and **12509307**. As long as your original part number is on our list, this unit will work perfectly once programmed to your VIN. Please enter it in the payment notes and save to ensure we receive it. Orders without a VIN within our 2-business-day handling period may be canceled, as programming cannot proceed without it. ### Shipping - **Processing Time:** Reliably shipped within 2-3 business days. ### Warranty Enjoy peace of mind with a **one-year replacement warranty** on this part, effective from the date you receive it. Labor costs are not covered. If the part fails within the warranty period, we’ll replace it with a comparable unit or refund your purchase price, ensuring a hassle-free experience. **Return Address:** **Highway71autoparts** **9131 Highway 71 NE** **Spicer, MN, 56288**
