Feature 1Find errors and diagnose OBD connector link in the process of using the decoder. 2Monitor the voltage and ground of the OBD interface and display low voltage. Shows diagnostic stitching error. 3Jump to OBD interface signal. Signal lines, such as decoders for 7 to 15 vehicles online. 4Quickly check whether each pin of the OBD2 diagnostic connector communicates normally. 5When replacing the battery, plug the OBD2 connector into the car and connect the additional power supply to the control box to ensure that vehicle data will not be lost.Item Type: OBD DetectorMaterial: ABSIntroduction:OBDII Protocol Detector & Break Out Box mainly used for car OBD line signal judgment and signal transfer. Using car fault diagnosis instrument can quickly determine car OBD signal receiving. Signal may not meet angle can take other signal transfer angle. Application is very convenient and solves risks across the line.This OBDII Protocol Detector & Break Out Box has wide range of applications in diagnostics, key programming and chip tuning. Function:To monitor data steam while performing test on vehicle using a Scan tool. This makes it possible for you to both execute a test and simultaneously monitor the testing process.Display testing voltage on the car or truckDisplay communicating pin numberIs an extension of OBD Diagnostic Link Connector (DLC) For short circuiting of pins To detect isolated circuits problems Is a power extension cord for small DC testers that need an external power source (maximum 1.2 amps.) To test circuits with a meter or scope. To check Power (Pin 16), Chassis Ground (Pin 4) and Signal Ground (Pin 5)Save ECU data when replacing vehicle battery. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x OBD Box1 x Connection Cable1 x CD
