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 of Jumper box and jumper
Introduction of Jumper box:
There are 15 jacks on jumper
box 15:1、2、3、GND、6、7、

Introduction of jumper:
There are 16 jumpers of
red, black and yellow color
in total in assembly box.
For the convenience of
distinguish ,

connect to power positive;
black jumper connect to
power negative,
yellow jumper connect to
signal wire. There are 4
kinds of jumper pins: sheet
pin, cylindrical, square
hole,
round hole, for convenient
use to various kinds of
diagnostic port pin shape.
Choose appropriate one
according to pin of vehicle
