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. ➤ 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.【LED Indicator Light】The LED light in the input socket can quickly display whether the power and ground of the OBD II interface on the vehicle are normal.➤ 4.【OBD Voltage Display】Can quickly measure the voltage value of the car OBD II interfaceand display it intuitively on the screen.➤ 5.【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.➤ 6.【OBDII 16 Pins Design & 45CM 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.➤ 7.【DC Power Jack】 Connect the power supply of DC 8V-30V,which can be used to replace the battery after powering the car ECU. • OBD Voltage DisplayCan quickly measure the voltage value of the car OBD II interface and display it intuitively on the screen. • LED Indicator LightThe LED light in the input socket can quickly display whether the power and ground of the OBD II interface on the vehicle are normal.RED LEDWhen the vehicle powersupply is normal, the redLED on pin 16 remains on for a long time.GREEN LEDWhen the vehicle is grounded normally, the green L ED on pins 4 and5 remains on for a long time.YELLOW LEDWhen the decoder communicates with the vehicle, the yellow LED at pin 2 or 6/ 7/10/14/15 has a signal waveform. Diagnostic Instrument Interface 4mm Banana Connector PortCan be connected to a multimeter or an oscilloscope for testing DC Power JackConnect the power supply of DC 8V-30V,which can be used to replace the battery after powering the car ECU 45CM Good Quality Extention CableThe cable body is made of elastic thermoplastic TPU material,which is characterized by high elasticity, high flexibility and high strength PIN DEFENITION DESCRIPTION 1 Self-Define by car manufacturer 2 SAE-J1850 PWM CAN(+) to test the communication between the code reader and the vehicle 3 Self-Define by car manufacturer 4 Body ground to test the car body grounds normally or not 5 Signal ground to test the signal grounds normally or not 6 CAN high (ISO 15765-4 and SAE-J2284) to test the communication between the code reader and the vehicle 7 K-line for ISO 9141-2 and ISO 14230-4 to test the communication between the code reader and the vehicle 8 Self-Define by car manufacturer 9 Self-Define by car manufacturer 10 SAE-J1850 PWM CAN(-) to test the communication between the code reader and the vehicle 11 Self-Define by car manufacturer 12 Self-Define by car manufacturer 13 Self-Define by car manufacturer 14 CAN low (ISO 15765-4 and SAE-J2284) to test the communication between the code reader and the vehicle 15 L-line for ISO 9141-2 and ISO 14230-4 to test the communication between the code reader and the vehicle 16 Battery positive to test the car body power supply is normal or not Operating OBD2 Breakout Box SafelyThis OBD2 breakout box is designed for use by automotive professionals. Improper use of this OBD2 breakout box can result in damage to the vehicle data communication system and associated circuits and systems. •Do not jumper pins together without understanding the circuits.•Do not use the OBD2 protocol detector to power up a load device exceeding 1 amp.
