It’s mainly used for changing automotive diagnostic OBD stitch to signal judgment level transfer. It can connect with any diagnostic instruments and judge whether car communication is normal. Also it can supply car power during replacing the battery , in order to prevent the body electrical equipment locked automatically. OBD2 Detector Break Out Box OBD Data Line Signal Diagnostic Scan Tool-Functions Test and find out the connection fault of OBD2 interface when using the tool. Monitor OBD interface voltage and ground wire so that it can display low voltage and fault diagnose Quickly test if every diagnostic stitch communication of OBD diagnostic interface is OK. Save automotive data and prevent automotive data losing and electric device. Usage-OBD2 Detector Break Out Box 1. Actually testing instructions1. In series connect OBD signal adaptor and car fault diagnostic tester. It supples power normally if its storage battery voltage LED displays more than 10V and NO.16, NO4 or NO.5 LED light. It’s shortage of storage battery voltage if less than 10V. None of LED turning light means that there is something wrong with the diagnostic holder power suppling, then check whether abnormal with the holder and storage battery voltage. 2. The communication signal LED will turn light during testing (Egg: NO. 7 wire signal). The testing of NO.7 pin is normal when LED flash,it means communicate normally. 3.The car diagnostic communication is NO. 15 wire but diagnostic tool is NO. 7 wire, it can’t test car in normal. OBD adaptor can connect NO.7 wire and NO.15 wire. When it test, NO.7 and NO.15 LED will turn light and flash. It can normally test. OBD Data Line Signal Diagnostic Scan Tool OBDII Protocol Detector Break Out Box mainly used 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 solve risks across the line. Indicator Light Meaning-OBD2 Detector Break Out Box 1. Manufactory custom. 2. SJE1850 wire(bus+) 3. Manufactory custom 4.
