Locating the OBD2 Fuse in Your 2004 Yukon

In most 2004 Yukon models, the OBD2 fuse is located within the interior fuse panel, often found beneath the driver’s side dashboard or in the glove compartment.

Troubleshooting a Blown 2004 Yukon OBD2 Fuse

A blown OBD2 fuse can prevent your scanner from communicating with your Yukon’s computer. Here’s how to troubleshoot the issue:

• Check the fuse: Visually inspect the fuse for a broken wire or a darkened glass section, indicating a blown fuse.
• Test with a multimeter: For a definitive test, use a multimeter to check for continuity across the fuse terminals. No continuity means the fuse is blown.
• Replace with the correct amperage: If the fuse is blown, replace it with a new one that has the exact same amperage rating. Using a higher amperage fuse can lead to electrical damage.
• Address underlying issues: A blown fuse is often a symptom of a larger problem. If the new fuse blows immediately or after a short period, you likely have a short circuit or another electrical issue that requires professional attention.
