Features:1.Highlights:-It is a latest testing platform for OBDII protocol detector & communication detection. It can convert the car OBDII interface into 6 pin for signal detection and electrical level conversion.-Connect with any diagnostic tool to tell whether the car communication is good or not.-Supply power to the car when you change the battery to avoid the vehicle control module data being lost, automatically locked, key remote control fails or the fault light turns on.2.OBDII protocol detector & communication detection:-Connect OBDII Break Out Box to the OBDII diagnostic port of the car.-After the device displays the voltage.-Then connect to the diagnostic tool, when the tool is communicating with the car, the LED indicator of corresponding protocol will light up or flash. ( If the CAN protocol is detected, it will have the maximum brightness. When the communication is successful, the corresponding CAN-H and CAN-L will dim or twinkling weakly)3.Convert OBD1 diagnostic interface to the standard OBDII:-Use the connector to convert the OBD1 interface into OBDII interface according to the diagnostic interface communication protocol.4.Able to power the car when replacing the used battery:-Prepare additional battery A to supply power by connecting to No. 16 / 4 / 5 holes of OBDII Break Out Box & to the OBDII diagnostic interface of the car.-Then replace the brand-new battery B with the used battery in the car, which will ensure that the car has fully power to prevent data loss and audio lock-up or the malfunction due to lack of power to the ECU control module.-Extend the car's OBDII 16 PIN interface to tell you whether the OBDII interface connection is good or not, which is convenient for the test of OBDII interface voltage waveform.Specifications:Item name: OBD Break Out BoxItem type: Electrical Testers & Test LeadsDimensions: approximately 15 x 9 x 4 cm/5.90 x 3.54 x 1.57 inches.Package List :1 x OBD2 Break Out Box1 x Pin CableNote:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
