OBD2 Breakout Box Automotive OBDII Protocol Monitor Car 16-Pin CAN Power/Ground Detector for 12V/24V Petrol and Diesel Cars Trucks

【Wide Application】This is an automotive diagnostic tool used to car OBD line signal judgment and signal transfer.You can monitor the OBD interface voltage and ground. In the process of using decoder, error can be found and diagnosed OBD connector link.as well as powering the on-board computer,testing OBD voltages,etc. 【Professional Testing】OBD2 Breakout box can help you measure whether the communication, power supply, and grounding of the vehicle OBDII interface are normal by connecting scanning tools. It not only detects car signals, but also some diesel signals, such as pins 2/6/7/10/14/15 can measure K-line, L-line, CAN bus and PWM protocol lines. Pins 4 and 5 can check whether vehicle body/signal grounding is normal, and pin 16 can check whether the power supply is normal.
