The Power Probe OBD-II Breakout Box is a CAN Bus circuit tester compatible with 12 and 24 Volt systems. The tool connects directly into the vehicle's Data Link Connector (DLC), testing for any abnormalities such as shorting and reverse polarity at the pins. If shorting or reverse polarity is present, connecting the HU-PPECB first will prevent harm before connecting a Diagnostic Scan Tool.
The Breakout Box provides a live display of present communicating signals without having to use a Digital Multimeter. - SELF POWERED No need for a separate power source - COMPATIBLE WITH MOST DIAGNOSTICS TOOLS AND MULTI METERS Not included - OBD CIRCUIT TESTER
