Q: Do I need a battery or separate power source to use this scanner?

A: No battery is required. The OBD2 scanner draws power directly from your vehicle's OBD2 diagnostic port, so it's always ready to use whenever you need it — no charging or batteries needed.

Q: Can this tool clear the check engine light after reading the fault code?

A: Yes! After reading the Diagnostic Trouble Code (DTC) and addressing the underlying issue, this scanner can clear the fault code and turn off the check engine light directly from the device menu.

Q: What does the voltage tester and charging tester function do?
