Review: Makes OBD2 diagnostics so much easier - Have had a lot of highspeed can bus issues lately on cars. (Been a tech for 23 years, specifically with electrical and computer diagnostics). Plugging this into the OBD2 port on a car gives me quick verification of battery power supplies at connector, grounds and CAN bus activity. The ability to tap into the banana connectors while a scan tool is plugged in also is fantastic for reading waveforms with an oscilloscope. Also checking overall CAN bus resistance unpowered using the banana plug taps makes diag much faster and more convenient than trying to GENTLY probe the OBD2 connector itself which sometimes are buried in the depths of a dashboard. Fantastic tool and well worth the money for quick preliminary and some more advanced testing.
Review: Game changer for mechanics! - Game changer for doing in car diagnostics when you cant get voltage readings to be consistent. So fast, so easy, and really clear instructions on what to do! Its a must have for any shop who is serious about repairing cars

## Features

- 【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.
- 【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 OBDⅡ 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.
