Understanding the 2011 Jeep Compass fuse box diagram is essential for any owner looking to perform DIY repairs and avoid costly trips to the dealership. This guide provides a detailed roadmap of the vehicle’s “Totally Integrated Power Module” (TIPM), which acts as the brain for your Jeep’s electrical distribution. By mastering this diagram, you will learn how to identify specific circuits, understand the relationship between different electronic components, and safely troubleshoot issues that could otherwise leave you stranded on the side of the road.
Comprehensive Breakdown of the 2011 Jeep Compass Fuse Box Diagram
The 2011 Jeep Compass utilizes a single, primary fuse and relay center known as the Totally Integrated Power Module (TIPM). Unlike many vehicles that split fuses between an engine bay compartment and an interior cabin panel, the Compass centralizes almost all critical protection devices under the hood. The 2011 Jeep Compass fuse box diagram reveals a grid-like layout where each slot is assigned a specific alphanumeric code, such as “M1” or “J10.”
The diagram is divided into two primary types of protective devices. First, there are the “J-Case” fuses, which are larger, square-shaped components typically used for high-draw systems like the cooling fan or the starter motor. Second, you will find “Mini-Fuses,” which are the smaller, two-pronged blades used for lower-amperage circuits like the ECU (Engine Control Unit), interior lighting, and audio systems. Understanding this distinction is vital because a blown J-Case fuse often indicates a more significant mechanical load issue, whereas a blown mini-fuse is frequently caused by a simple short circuit or a faulty accessory.
The TIPM is located in the engine compartment on the driver’s side, directly adjacent to the air filter housing. To access the diagram, you must depress the plastic tabs on the cover and lift it upward. A simplified version of the diagram is usually embossed on the underside of the plastic lid.
The visual breakdown of the module also includes several empty slots. These are intentional and vary based on whether your Jeep is equipped with specific features like heated seats, a sunroof, or four-wheel drive. If your diagram shows a fuse for a component your vehicle doesn’t have, it is simply a standard manufacturing design for the universal TIPM housing.

Step-by-Step Guide to Using the Fuse Box Diagram
Navigating an automotive electrical system can be intimidating, but following a structured approach ensures safety and accuracy. Use these steps to interpret the 2011 Jeep Compass fuse box diagram and resolve your electrical issues.
1. Preparation and Safety First
Before touching any electrical component, ensure the ignition is completely off and the key is removed. Electrical surges can damage the sensitive ECU if you pull fuses while the system is energized. Wear safety glasses to protect against potential sparks or plastic fragments.
2. Locate the Integrated Power Module
Open the hood and find the black rectangular box on the driver’s side. This is the TIPM. Clean the exterior of the box before opening it to prevent debris from falling into the terminal slots.
3. Identify the Symptomatic Circuit
Match your vehicle’s symptom to the corresponding fuse on the diagram. For example, if your OBD-II port is not providing power to a scanner, you will need to locate the fuse responsible for the Diagnostic Link Connector. If the vehicle is running hot, you would look for fuses related to the radiator fan to ensure proper coolant flow is maintained.
4. Extract the Fuse for Inspection
Using the fuse puller tool (often located inside the fuse box or in a standard tool kit), gently grasp the suspected fuse and pull it straight up. Avoid rocking it back and forth, as this can bend the internal metal terminals.
5. Visual and Multimeter Verification
Hold the fuse up to a light source. Look for a broken metal filament inside the plastic housing. However, visual inspection isn’t always 100% reliable. Use a digital multimeter set to the “Continuity” or “Ohms” setting. Place the probes on the two small metal test points on top of the fuse. If the meter beeps or shows near-zero resistance, the fuse is good.
6. Check for Diagnostic Codes
If a fuse related to the engine management system has blown, your dashboard might display a check engine light. Even after replacing the fuse, use an OBD-II scanner to check for a stored diagnostic code. This can tell you if a sensor, such as an O2 sensor or a camshaft position sensor, caused the circuit to overload.
7. Replace with Correct Amperage
Never replace a fuse with one of a higher amperage rating. If the diagram calls for a 10A (red) fuse, do not use a 20A (yellow) fuse. Doing so can cause the wiring harness to melt or start a fire before the fuse has a chance to blow.
8. Reassemble and Test
Snap the TIPM cover back into place securely. The seal must be tight to prevent moisture from entering, which can lead to corrosion. Start the vehicle and test the component to verify the fix.
If a fuse blows immediately after replacement, do not keep replacing it. This indicates a “hard short” in the wiring. Continually forcing power through a shorted circuit can destroy the TIPM, which is a very expensive component to replace.
Common Electrical Issues and Troubleshooting
The 2011 Jeep Compass is known for specific electrical quirks that can often be traced back to the fuse box. One frequent problem involves the “no-start” condition where the starter motor refuses to engage. Using the 2011 Jeep Compass fuse box diagram, owners often find that the J13 fuse (Starter Solenoid) has failed.
Another common issue involves the check engine light appearing alongside transmission “limp mode.” In these cases, the fuse powering the ECU or the transmission control module may be intermittent. If you find that fuses are intact but systems are failing, the problem might be the internal circuitry of the TIPM itself, which is prone to internal relay failure.
Warning signs of a failing electrical distribution system include:
- ✓ Intermittent loss of power to the radio or windows.
- ✓ Headlights staying on even when the vehicle is turned off.
- ✓ The windshield wipers activating on their own.
- ✓ Inability to communicate with the vehicle via the OBD-II port.
If you encounter these “ghost” symptoms, use the diagram to identify the main power feed fuses. If those are clear, it may be time to consult a professional for a TIPM reset or replacement.
Pro Tips and Maintenance Best Practices
Maintaining your Jeep’s electrical health goes beyond just replacing fuses. To ensure long-term reliability, consider these expert recommendations:
Apply a small amount of dielectric grease to the terminals of a new fuse before installation. This prevents moisture from causing corrosion, which is a common cause of high resistance and heat buildup in the fuse box.
Regularly inspect the physical condition of the engine bay. For instance, ensure the accessory belt is in good condition; a slipping belt can cause the alternator to provide inconsistent voltage, which stresses the fuses and the ECU. Similarly, keep an eye on mechanical components like the timing chain. While the timing chain is mechanical, the sensors that monitor its position (and send data to the ECU) are electrically powered. An electrical fault in the TIPM can cause “false positive” timing codes.
When working on the battery, always follow the proper torque spec for the terminal clamps. Loose battery terminals can cause arching, which sends electrical “noise” through the fuse box and can lead to blown fuses or corrupted diagnostic codes. Generally, 10 to 12 lb-ft of torque is sufficient for most battery terminals to ensure a solid connection without stripping the bolts.
Lastly, always invest in high-quality fuses. Cheap, unbranded fuses may not blow at their rated amperage, which puts your entire wiring harness at risk. Stick to reputable brands that meet OEM specifications to protect your 2011 Jeep Compass from preventable electrical damage. By combining the knowledge from the 2011 Jeep Compass fuse box diagram with these maintenance tips, you can keep your vehicle running smoothly for years to come.
