Have you ever been in the middle of diagnosing your 2005 Chevy Equinox, only to find your scan tool isn’t getting any power? This frustrating experience can leave you stranded and clueless about what’s wrong with your vehicle. Don’t worry, you’re not alone. This is a common issue that many Equinox owners face.
What Does It Mean When Your Scan Tool Has No Power?
When your scan tool doesn’t power up when connected to your 2005 Chevy Equinox, it indicates a problem with the electrical connection between your vehicle and the scan tool. This problem could be related to a blown fuse, a faulty wiring harness, or even a problem with the OBD-II port itself.
Troubleshooting Steps for No Power to Scan Tool
1. Check the Fuses
The first step in troubleshooting a scan tool with no power is to check the fuses. The OBD-II port is usually powered by a dedicated fuse in the fuse box. Check your owner’s manual for the location of the fuse box and the specific fuse responsible for the OBD-II port.

2. Inspect the Wiring Harness
If the fuses are all good, the next step is to inspect the wiring harness. The wiring harness connects the OBD-II port to the vehicle’s computer system. Look for any signs of damage, such as frayed wires, corrosion, or loose connections.

3. Test the OBD-II Port
If you’ve checked the fuses and wiring harness and still can’t get power to your scan tool, the problem may be with the OBD-II port itself. You can test the port using a multimeter.
