OBDII Protocol Detector & Break Out Box OBD2 Detector Signal Switching Box

Highlights of OBDII Break Out Box:

1. This is a latest testing platform for OBDII Protocol Detector & Communication Detection.

2. It can convert the car OBD2 interface into 6 pin for signal detection and electrical level conversion.

3. Connect with any diagnostic tool to tell whether the car communication is good or not.

4. 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.

OBDII Protocol Detector & Communication Detection：

1. Connect OBDII Break Out Box to the OBDII diagnostic port of the car.

2. After the device displays the voltage.

3. 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)

Able to power the car when replacing the used battery:

1. Prepare additional battery A to supply power by connecting to No. 16 / 4 / 5 holes of OBDII Break Out Box & to the OBD2 diagnostic interface of the car.

2. 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 16pin interface to tell you whether the OBDII interface connection is good or not, which is convenient for the test of OBDII interface voltage waveform.

Convert OBD1 diagnostic interface to the standard OBD2:

Use the connector to convert the OBD1 interface into OBD2 interface according to the diagnostic interface communication protocol.
