DUOYI Breakout LED Light Auto OBDII Protocol Detector 16-Pin Breaker Box

[OBD2 breakout box With Pass-Through Feature]OBD2 breakout box is a car diagnostic tool with pass-through function, which can connects inline between your OBDII diagnostic port and your ODB 2 reader or other ODB 2 device for effective and safe monitoring signals of protocol, power and grounds, and you can also use it to charge scanning tools via the ODB II port. Additionally, the breakout box can also be connected to a multimeter or oscilloscope for further detection of unconfirmed signals.

Features:
- [Detect CAN bus/K-line/L-line/PWM Protocol Line]OBD2 breakout box works great for communication line diagnoses, which not only helps you see the OBD signals as they are operational, but also detect some diesel signals, such as CAN bus, K-line, L-line and PWM protocol line. You can place this OBD2 breakout box between your diagnostic tool and your vehicle, which makes bus can and K-line diagnostics easier.
- [LED Indicator]Breakout box is designed with LED indicators that you quick visual indicators of the state of each data line plus power and ground via led lights.When vehicle body is properly grounded,Green LED of pins 4 and 5 will be on;when the power supply is normal,Red LED of pin 16 will be on;when the decoder communicates with the vehicle,pin 2 or 6/7/10/14/ 15 has signal waveform.Breakout box makes it super easy to test for good connections at the pins without dealing with finicky probes.
- [16 pins OBDII Interface 90cm Cable]OBD interface of the detector adopts a 16 pins design,the input jack layout fully emulates the 16-pin layout of the OBD interface,allowing more tests to be performed quickly and intuitively,you can have quick access to all 16 pin connections during vehicle service and diagnostics.You do not need to directly operate the pins of the OBDII interface.The cable length of the OBDII data line detector is 90 cm,which makes the device connection more convenient.
- [16 Standard 4mm Banana Sockets Male and Female Connectors]The built-in input jack of the OBD2 breakout box can connect any type of 4mm banana plug, you can connect a multimeter or oscilloscope to any jack to check voltages or signal levels. OBD2 breakout box has male and female connectors for connecting the car OBDII system and the scan tool, so that after you connect the scan tool, you can also detect each pin on the connector through the breakout box.
- [Note]Do not place a jumper between the power pin 16 and ground pins 4 and 5; Do not use this tool to power up a load devices exceeding 1 amp; Do not jumper pins together without understanding the circuits.
