Programmed 2012 Impala Fuel System Control Module 20877116

### Programmed 2012 Impala Fuel System Control Module 20877116   ## Restore Your Impala’s Fuel Delivery and Performance Is your 2012 Chevrolet Impala experiencing frustrating issues like extended cranking times, sudden stalling, or a check engine light that just won’t go away? Before you suspect the fuel pump itself, the problem often lies with its electronic brain: the Fuel System Control Module (FSCM). As a technician with over two decades of experience, I’ve seen countless vehicles sidelined by this critical component. This module is responsible for precisely managing the voltage sent to your fuel pump, ensuring your engine gets the exact amount of fuel it needs under all driving conditions. When it fails, performance suffers and you risk being left stranded. The biggest headache with replacing an FSCM has always been the required programming. Traditionally, this meant installing the part and then towing your vehicle to a dealership for an expensive calibration session. We eliminate that step completely. This is a direct-fit **2012 Impala Fuel System Control Module** that arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. It’s a true plug-and-play solution that saves you time, money, and the hassle of a dealer visit. #### A Technician’s Notebook: The Intermittent Stall Case I remember a 2012 Impala that came into the shop with a complaint that stumped two other mechanics. The car would run perfectly for days, then suddenly stall at a stoplight and refuse to restart for 10-15 minutes. There were no consistent trouble codes, just a history log of a U0109 (Lost Communication with FSCM). We checked wiring and the fuel pump, which all tested fine. On a hunch, I tapped the FSCM, located in the right rear quarter panel, and the engine immediately stumbled. The module had an internal intermittent failure, likely from years of vibration and heat cycles. Replacing it with a pre-programmed unit solved the problem for good. This isn’t just a part; it’s a permanent fix for a tricky diagnostic issue. #### Is Your Impala Showing These Symptoms? A failing FSCM can manifest in several ways. If you’re noticing any of the following, this module is the most likely solution: - ✔ Engine cranks but won’t start - ✔ Stalling, especially when coming to a stop or under load - ✔ Hesitation or stumbling during acceleration - ✔ Rough idle or inconsistent engine performance - ✔ Check Engine Light with codes like P069E, P0230, or U0109 - ✔ A noticeable whining from the fuel pump area #### A Straightforward Guide to Installation Replacing the **2012 Impala Fuel System Control Module** is a job most DIYers can handle in their own garage. Here’s a basic overview of the process: 1. **Safety First:** Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. 2. **Locate the Module:** On the 2012 Impala, the FSCM is typically located in the trunk, behind the trim panel on the right-hand (passenger) side quarter panel. 3. **Access the Module:** You will need to remove the trunk carpeting and plastic trim panels to gain access to the module. 4. **Disconnect and Remove:** Carefully unplug the electrical connector. Then, unbolt the old module from its mounting bracket. 5. **Install the New Module:** Bolt the new, pre-programmed FSCM into place and securely reconnect the electrical harness. Ensure the connector clicks into place. 6. **Reassemble and Test:** Reinstall the trim panels and carpeting. Reconnect the battery terminal, turn the key to the ‘On’ position for a few seconds to prime the system, and then start the engine. #### Verified Vehicle Compatibility This module is a direct replacement for part number **20877116** and is also compatible with part numbers **20791901**, **20827745**, and **20850927**.

This ensures perfect communication with your vehicle’s other computers and guarantees a seamless, plug-and-play installation. **Is this part difficult to install myself?** For most individuals with basic hand tools, this is a very manageable DIY repair. The primary challenge is accessing the module behind the trunk trim. Since no programming is required on your end, it’s a simple unbolt-and-replace procedure. **Will this fix a P069E code?** Yes, a Diagnostic Trouble Code (DTC) P069E (Fuel Pump Control Module Commanded OFF) is one of the most common indicators of a failed FSCM. Replacing the module is the standard and effective repair for this code. **What’s the difference between this and one from a local parts store?** The key difference is our pre-programming service. A module from a local store will be a blank unit, requiring you to take the vehicle to a shop with expensive diagnostic tools for software flashing. Our module is ready to install right out of the box, saving you that significant extra cost and step. 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.
