Features 1、Find errors and diagnose OBD connector link in the process of using the decoder. 2、Monitor the voltage and ground of the OBD interface and display low voltage. Shows diagnostic stitching error. 3、Jump to OBD interface signal. Signal lines, such as decoders for 7 to 15 vehicles online. 4、Quickly check whether each pin of the OBD2 diagnostic connector communicates normally. 5、When 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. Specification Item Type: OBD Detector Material: ABS Introduction: 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 truck Display communicating pin number Is 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.
