Vehicle power is not detected — Scan tool not receiving power from the vehicle

What does Vehicle power is not detected mean?

The scan tool is not getting power from the vehicle's OBD-II port. This means it cannot communicate with the car's computer systems.

• Scan tool not properly connected to the vehicle's OBD-II port
• Vehicle ignition is not turned on
• Blown fuse for the OBD-II port or cigarette lighter (if powered through that)
