Key Features

Key Features

The upgraded OBD2 breakout box helps technicians monitor OBD2 power, ground, communication pins and voltage display while connecting diagnostic instruments, multimeters, oscilloscopes or ECU backup power more conveniently.

OBD Voltage Display

The built-in display quickly measures and shows OBDII interface voltage, helping users check whether the OBD2 connector voltage is normal.

LED Indicator Light

LED indicators help show vehicle OBD2 power, ground and communication signal status. Red indicates pin 16 power, green indicates pin 4 / 5 ground, and yellow indicates communication signal activity.

16-Pin Input Jack

The built-in input jack fully emulates the OBDII 16-pin layout and can be used with a 4mm banana plug, multimeter or oscilloscope for pin-level testing.

Diagnostic Instrument Interface

When the diagnostic instrument communicates with the vehicle, the breakout box allows quick access to the OBD2 16 pins for monitoring and diagnosis.

DC Power Jack

The DC interface can connect to a 12V backup battery, helping supply temporary ECU power and support battery replacement or ECU power maintenance scenarios.

45cm TPU Extension Cable

The 45cm TPU cable is designed with high elasticity, high flexibility and high strength for easier use around vehicle OBD2 ports.
