How to use Fcar Jumper to diagnose connectors in different shapes of pin for most vehicles
Fcar automotive diagnostic tool is equipped with various kinds of diagnostic connectors in different shapes of pin for most vehicles. Yet for part of models, Connection failure occurs although used corresponding diagnostic connectors due to disunity of diagnostic connector connection methods or artificial damage, refitting or wrong connection of diagnostic connector. For such cases, you can use jumper box for jumper connection.

Introduction <strong>of</strong> jumper:<br />
There are 16 jumpers <strong>of</strong><br />
red, black and yellow color<br />
<strong>in</strong> <strong>to</strong>tal <strong>in</strong> assembly box.<br />
For the convenience <strong>of</strong><br />
dist<strong>in</strong>guish ,<br />
red jumper normally
connect <strong>to</strong> power positive;<br />
black jumper connect <strong>to</strong><br />
power negative,<br />
yellow jumper connect <strong>to</strong><br />
signal wire. There are 4<br />
k<strong>in</strong>ds <strong>of</strong> jumper p<strong>in</strong>s: sheet<br />
p<strong>in</strong>, cyl<strong>in</strong>drical, square<br />
