2010 Chevy Traverse Fuel Pump Control Module Location: What Every Owner Should Know

The fuel pump control module on a 2010 Chevy Traverse is located on the rear crossmember, underneath the vehicle, near the fuel tank. This small electronic module, sometimes called the fuel pump driver module or chassis control module, sits outside the fuel tank and controls how fast the in-tank fuel pump runs. It is a common failure point on these vehicles, and knowing exactly where it is can save you hundreds of dollars in diagnostic fees. The module is mounted to the rear crossmember on the driver's side, just ahead of the rear bumper, and is accessible without dropping the fuel tank. In this guide, we'll walk you through the exact location, how to identify it, common symptoms of failure, and what it costs to replace.

What Is the Fuel Pump Control Module and Why Does It Matter?

The fuel pump control module (FPCM) is a separate computer that tells the in-tank fuel pump how fast to run based on the engine's fuel demand. It is not the same as the fuel pump assembly itself. The fuel pump assembly is the mechanical pump and sending unit inside the gas tank, while the FPCM is a smaller electronic module mounted outside the tank. On the 2010 Traverse, the FPCM is a known weak point and should be checked before condemning the much more expensive in-tank pump. The module typically costs between $70 and $125 for the part alone, while replacing the entire fuel pump assembly involves dropping the fuel tank and can cost over $1,000. If your Traverse is stalling, struggling to start, or showing a check engine light with a fuel system code, the control module is often the first thing to inspect.

Exact Location of the Fuel Pump Control Module

The module is bolted to the rear crossmember, underneath the vehicle, roughly in line with the rear seat area. To access it, you will need to get under the car. Here is the step-by-step process:

1. Park the vehicle on a level surface and engage the parking brake. For safety, use jack stands or ramps to lift the rear of the vehicle. Never rely on a floor jack alone.
2. Slide under the rear of the vehicle, near the center. Look for the rear crossmember, which is a horizontal metal bar that runs side to side. The module is attached to this crossmember, typically on the driver's side, just forward of the rear axle.
3. Look for a small black plastic or metal box with an electrical connector. The module measures roughly 3 to 4 inches on each side and has a wiring harness plugged into it. Some models have a metal mounting bracket holding it in place with two bolts.
4. If you have trouble spotting it, follow the fuel lines from the fuel tank forward. The module is usually mounted close to where the fuel lines run along the frame rail.

One important note: the exact location can vary slightly depending on whether your Traverse is equipped with certain options. On some models, the module may be mounted on the left frame rail rather than directly on the crossmember. If you cannot find it, check both sides of the rear underbody. A salvage yard parts listing confirms that the module is commonly described as "fuel pump (rear crossmember)" for the 2010-2012 Traverse, which matches the rear underbody location.

How to Identify the Correct Part Number

The factory part number for the fuel pump control module on the 2010 Chevy Traverse is 20877116. General Motors also lists this module as "Module, Fuel Pump Flow Control" and it replaces earlier part numbers including 20850927, 20791901, and 20827745. When shopping for a replacement, you may see any of these numbers. They are interchangeable in most cases. Some aftermarket parts use different numbers like 601-131 or 25780327, but the OEM number to match is 20877116. Be cautious: the module requires programming or special setup procedures after installation according to GM Genuine Parts. Some sellers offer pre-programmed modules that are ready to install if you provide your VIN.

Common Symptoms of a Failing Fuel Pump Control Module

A bad FPCM can cause a variety of driveability problems. Here are the most common signs:

1. Hard starting or no-start condition. The engine may crank normally but take a long time to fire up. In severe cases, it will not start at all.
2. Stalling while driving. The engine may die suddenly, especially at low speeds or when idling. This is particularly dangerous in traffic.
3. Weak acceleration. The vehicle may feel sluggish, and you may need to press the gas pedal harder to get it moving.
4. Increased fuel consumption. A faulty module can cause the fuel pump to run at the wrong speed, pushing extra fuel into the engine. You may notice the gas gauge dropping faster than usual.
5. Check engine light with fuel-related codes. The most common code is P069E, which indicates a fuel pump control module request. Owners have also reported the module getting contaminated by moisture, which is one reason GM issued a special coverage bulletin for some of these vehicles.

On the 2009-2010 Traverse and its sister vehicles (GMC Acadia, Buick Enclave, Saturn Outlook), the FPCM has a notably high failure rate. If your car is stalling or hard to start, diagnosing the module first is highly recommended because it is a much cheaper and easier part to replace than the in-tank pump. If a new module does not solve the problem, or fails again quickly, the real issue is likely the in-tank pump drawing too much current.

Replacement Cost and What to Expect

The total cost to replace the fuel pump control module on a 2010 Traverse depends on where you buy the part and whether you do the work yourself. Here's a realistic breakdown:

• Part cost: Aftermarket modules run from about $70 to $125. Original GM parts are usually more expensive, around $124 to $140. Used OEM modules from salvage yards can be found for as little as $100, but they come with the risk of unknown condition.
• Labor cost: If you pay a shop to do it, expect to pay $100 to $200 for the replacement. The job itself is simple, taking about 30 minutes for a mechanic. The main cost is diagnostic time.
• Dealer programming: Because the module may require programming, some owners have paid $300 or more at a dealership for a new programmed module. Online services offer pre-programmed used modules for around the same price, which can be a good option if you want plug-and-play convenience.

One owner on a forum reported paying about $300 for a new module and programming after a dealer diagnosed the issue. The damage could have been worse if more diagnostics were run first. If you are handy, you can save the labor cost by doing the replacement yourself and then having the module programmed at a shop or using an online service that pre-programs it for you.

Step-by-Step Replacement Guide for DIYers

If you are comfortable working under your vehicle, replacing the module is a straightforward job. Here's how to do it:

1. Disconnect the negative battery cable. This reduces the risk of electrical shorts while working near the module.
2. Remove the right-side trim panel in the trunk (for some models) or simply access the module from underneath. On the Traverse, the module is under the car, so lifting the rear with jack stands is the main access step.
3. Disconnect the electrical connector from the module. Press the release tab and pull the connector straight out. Do not force it.
4. Remove the retaining bolts that hold the module to the crossmember or bracket. Use a socket or wrench to loosen them, then lift the module free.
5. Install the new module in reverse order. Bolt it in place, reconnect the electrical connector, and reconnect the battery.
6. Start the vehicle and check for proper operation. If the module requires programming, you will need to visit a dealer or use a scan tool to complete the setup.

Always work in a well-ventilated area and have a fire extinguisher on hand when working around fuel system components.

Important Safety Note About the Fuel Pump

Keep in mind that the 2010 Traverse actually has two fuel pumps. One is a low-pressure pump inside the fuel tank, and the other is a high-pressure pump attached to the side of the engine, below the throttle body. The control module we discussed controls the in-tank pump. If you are experiencing fuel delivery issues, a proper diagnosis is critical to avoid replacing the wrong component. Check the fuel pump connector under the driver's seat for corrosion or poor connection, as this can mimic a failing module. Ensure the connector is fully seated and terminals are clean before condemning any part.
