Understanding your 2006 Saturn Vue’s fuse box is crucial for diagnosing and resolving electrical issues, especially when it comes to using your OBD2 scanner. Locating the correct fuse for your OBD2 port or related systems can save you time and money on car repairs. This guide will walk you through the fuse box locations in your 2006 Saturn Vue and pinpoint fuses relevant to your OBD2 diagnostic process.
Your 2006 Saturn Vue is equipped with two primary fuse box locations: the Instrument Panel Fuse Block and the Underhood Fuse Block. Each of these fuse boxes houses fuses and relays that protect different circuits throughout your vehicle. Knowing the location and function of each fuse is essential for effective troubleshooting.
Instrument Panel Fuse Block Location and Diagram
The Instrument Panel Fuse Block in your 2006 Saturn Vue is located inside the vehicle. While the exact location might slightly vary, it is generally found on the driver’s side, often behind a panel beneath the steering wheel or on the side of the dashboard, accessible when the driver’s side door is open.
Once you locate the Instrument Panel Fuse Block, you’ll need a diagram to identify the specific fuses. Here is a diagram and description of the fuses in the Instrument Panel Fuse Block of your 2006 Saturn Vue:

Important Fuse for OBD2: Fuse #13 (RADIO) – Data Link Connector
Notably, Fuse #13 in this panel is labeled “RADIO, Data Link Connector”. This is a crucial fuse to check if you are experiencing issues with your OBD2 scanner not powering up or connecting to your 2006 Saturn Vue. A blown fuse #13 could directly prevent your OBD2 scanner from communicating with the vehicle’s computer.
Underhood Fuse Block Location and Diagram
The Underhood Fuse Block is located in the engine compartment of your 2006 Saturn Vue, typically near the battery or on a fender wall. It is usually enclosed in a protective black plastic box.
Once you’ve found the Underhood Fuse Block, use the following diagram and table to understand the function of each fuse and relay:

Fuses Potentially Affecting OBD2 Functionality:
While Fuse #13 in the Instrument Panel Fuse Box is the most direct fuse related to the Data Link Connector (OBD2 port), other fuses in the Underhood Fuse Block are also important for overall OBD2 system functionality. These include:
- Fuse #1 (Battery Voltage to ECM, TCM, PCM): This fuse powers critical engine and transmission control modules. If blown, it could prevent the OBD2 port from receiving necessary power or communication signals.
- Fuse #16 & #22 (Engine Control Module (ECM)): The ECM is the brain of your engine management system and essential for diagnostics. Fuses protecting the ECM are vital for OBD2 operation.
- Fuse #19 (Ignition Switch): While not directly OBD2 related, the ignition system must be functioning correctly for the OBD2 port to be active in many cases.
Troubleshooting OBD2 Issues with Fuses:
If your OBD2 scanner is not working on your 2006 Saturn Vue, follow these steps to check the fuses:
- Locate both Fuse Boxes: Identify the Instrument Panel and Underhood Fuse Boxes using the descriptions above.
- Consult Diagrams: Use the diagrams provided to locate Fuse #13 in the Instrument Panel Fuse Box and the other potentially relevant fuses in the Underhood Fuse Box.
- Visually Inspect Fuses: Remove each fuse using a fuse puller (often found in one of the fuse boxes, position #48 in the Underhood box). Hold the fuse up to the light and check if the thin wire inside is broken or melted. If it is, the fuse is blown.
- Test with a Multimeter (Optional): For a more accurate test, use a multimeter to check for continuity across the fuse terminals. No continuity means a blown fuse.
- Replace Blown Fuses: Replace any blown fuses with a new fuse of the exact same type and amperage rating.
- Test Your OBD2 Scanner: After replacing any blown fuses, try using your OBD2 scanner again to see if the issue is resolved.
Important Notes:
- Always replace a blown fuse with one of the same amperage. Using a fuse with a higher amperage rating can damage your vehicle’s electrical system.
- If fuses blow repeatedly, it indicates a larger electrical problem. Consult a qualified mechanic to diagnose and repair the underlying issue.
- Fuse box diagrams can sometimes vary slightly. Always refer to the specific diagram located inside your fuse box cover or your vehicle’s owner’s manual for the most accurate information.
By understanding the fuse box locations and diagrams for your 2006 Saturn Vue, and specifically focusing on fuses related to the Data Link Connector and engine control systems, you can effectively troubleshoot many OBD2 related issues and maintain your vehicle’s diagnostic capabilities.
