16PIN

DUOYI DY29 OBD2 Breakout Box is an automotive diagnostic tool for the OBDII diagnostic link connector which offers easy access to the OBDII connector for monitoring signals of protocol, power, and grounds conveniently and safely after connecting the car OBDII system. OBDII protocol detector can be also connected to multi-meter or oscilloscope for further testing once unconfirmed signals detected. OBDII breakout box is perfect for diagnosing and modifying your cars or trucks.Features: 1.【OBD2 Communication/Signal&Power Supply & Grounding Detection】Through different color LED lights on breakout box, you can quickly judge whether communication, power supply and grounding of OBDII interface on vehicle are normal. Yellow LED lights on indicate that OBD2 scanner is communicating with vehicle and the corresponding 2/6/7/10/14/15 pins have signal waveforms. When vehicle body is properly grounded, Green LED of pin 4 and 5 are on. When power supply is normal, Red LED of pin 16 is on.2.【CAN Bus/K-line/L-line/PWM Protocol Line Detection OBD2 Protocol Detector】OBD2 breakout box not only can detect car signal but also can detect some of diesel signal such as K-line, L-line, CAN bus and PWM protocol line. It is easier to measure CAN bus signals by placing a junction box between the breakout box and the vehicle.3.【OBD2 Scanner Detection & 4mm Banana Jack OBD2 Breakout Box】When you connect the OBD2 scanner, if the information on the OBD2 scanner screen is consistent with the light on the breakout box, it means that the OBD2 scanner is not faulty. The built-in input jack of the OBDII protocol detector can be connected to any type of 4mm banana plug. You can connect a multimeter or an oscilloscope to the banana jack to detect the detailed signal information of the corresponding lighted port.4.【OBDII 16 Pins Design & 35-inch Extension Cable of Breakout Box Automotive】The input jack layout of OBD2 protocol detector fully simulates the 16-pin layout of the OBDII interface,allowing more tests to be performed quickly and intuitively. When the OBD2 scanner communicates with vehicles, all 16 pins of OBDII breakout box can be easily connected. No need to directly operate the pins of the OBDII interface. OBD2 breakout box has female connector and male connector with a 35-inch extension cable.5.【Male/Female Header Connectors】 The OBD2 breakout box with male and female header connectors, so that this breakout box can be placed between the vehicle and the diagnosis tool. You can measure CAN bus signals very quickly, easily and safely. Probing the OBDII connector is no longer necessary. It is a 16-pin setup that simulatesthe OBDII interface, which enablesmore tests to be performed quicklyand intuitively Can be connected toany 4mm banana connectorsNote: Multimeter or oscilloscope can be connected to the banana jack which has signal waveform, such as pin 2, 4, 5, 6, 7, 10, 14, 15. The corresponding LEDs on the display can quickly indicate whether the power and ground of the OBDⅡ interface on the vehicle are normal•Red LED Signal Light: If the car power supply is detected as normal, the red LED of pin 16 will always be on.•Green LED Signal Light: If the car is detected grounded normally, the green LED of pin 4 and 5 will always be on.•Yellow LED Signal Light: When the code reader communicates with the vehicle, the yellow LED on pin 2 or 6/7/10/14/15 will occur a waveform signal.
