Product Features

• 2 in 1 Upgraded Version of NT301: Many car problems that seem engine-related are actually battery issues. A weak battery can trigger multiple error codes and cause poor performance.

This device functions as an OBDII module with fault code reading and clearing capabilities, as well as a 12V battery testing feature. It also does not perform load tests and only supports 12V batteries, not 6V or 24V types. It's a plug and play tool that does not bulit-in battery. Note: All our products are sold as brand new.
