GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.

- 【Auto OBD2 Breakout Box】 This is an Breakout Box OBDII Protocol Detector for the car OBDII diagnostic link connector, which provides easy access to the OBDII connector so that after connecting the automotive OBDII system, the different color LEDs on the OBD2 junction box can monitor the protocol, power and ground signals conveniently and safely, good helps detect if the problem is with the vehicle's ECU or decoder.
- 【LED flashing of OBDII Breakout Box】 LEDs provide a quick indication of OBDII Protocol Detect power or ground issues. When the code reader is communicating with the vehicle, the yellow LED (pin 2/6/7/10/14/15) lights up with a signal waveform. If a normal car ground is detected, the green LED (pin 4/5) will be on solid. If it is detected that the car power supply is normal, the red LED (Pin16) will be always on.
- 【Digital display and 16-pin interface design】 Auto 16 pin dlc breakout box an LED display design is added to first eliminate the voltage problem of the OBD port and easily determine whether the cable and the car OBD port are connected correctly. The port is designed with a 16-pin interface, when the OBD2 scanner communicates with the vehicle, it can easily connect all 16 pins of the OBDII junction box for more tests quickly and intuitively.
- 【4mm banana plug & 128cm extension cord】 The OTC Can test box has a safety banana socket that accepts all types of 4mm banana plugs. You can connect a multimeter or oscilloscope to the banana socket to detect the detailed signal information of the corresponding lit port. The cable length of the obd ii breakout testing box is 128cm, which makes device connection more convenient and you don't have to operate in a narrow space in the car.
- 【Strong safety performance】 This Auto ECU Breakout Box can prevent the power supply from being reversed, and the KW308 will sound an alarm when reversed connection occurs. It can protect the diagnostic tool from damage such as power short circuit. The product comes with a small flashlight to help plug the OBD port into the car when the light is low. (Do not jumper pins together without understanding the circuits. )
