DUOYI #ad - Notedo 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. After connecting the car diagnostic tester and the car obDII system, the communication protocol, power and grounds of the OBDII on-board diagnostic system can be monitored very simply and safely, which is a multifunctional OBD2 diagnostic connector detector.

It can be directly connected to the car's on-board data link and easily access the vehicle's data bus line. 16 standard 4mm banana sockets & male/female header connectorsthe built-in input jack can be connected to any type of 4mm banana plug for easy connection to a multimeter or oscilloscope to further measure the uncertain monitoring signal. In addition, obd2 protocol detector has male and female header connectors, you can place the junction box between the diagnostic tool and the vehicle, which is more convenient to measure the CAN bus signal.16 pins obdii interface&90cm cableobd 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. Obd signal&grounds&power detectionbreakout box can judge the obd signal reception. When the decoder communicates with the vehicle, if the yellow light is on for a long time, it indicates that the decoder is communicating with the vehicle, the green LED of pins 4 and 5 is on.

KAWISH Auto ECU Breakout Box -CAN Breakout Box OBDII Protocol Detector for OBDII Protocol Communication Detection/ECU Tool Maintenance/Diagnosis/Programming/Coding

#ad
KAWISH #ad - This tool must be able to indicate the signal on each signal line. If you have any unsatisfactory or good idea in the use, please contact us in time. Based on the above ideas, we have developed this tool, although it certainly has a variety of shortcomings, but we are still improving, and hope to make the best tool.

Sometimes it's difficult to plug the obd port into the car when the light is bad, so it's better for this tool to have a small flashlight. And battery voltage is also important for diagnosis, so it need to be clear read. Otherwise, i hope this tool can have a long cable, so i don't have to operate in the narrow space in the car. And this tool can't affect normal signal, It would be better to have a OBD male port for signal input and a OBD female port for output.

When diagnosing cars in the past. The decoder could not enter the car ECU system. I don’t know if it was the problem on the car ECU or decoder, so I needed a tool to indicate the signal line on the diagnostic interface. The indicate light is on when there is voltage, it is not on when there is no voltage, and the light is flashing when there is a signal.
