The function requires network connection.

Read instructions and wiring diagram.

For BENCH & BOOT (workbench) operation, please use a reliable high-power DC regulated power supply (current not less than 5A) to power the ECU. OBDSTAR’s standard power adapter (current 2A) is only used for device charging and is not recommended for ECU. power supply, otherwise communication may fail due to low power of the power adapter!

There are 3 connections available, you can use P003, P003+, or MP001 connection

To use P003 or P003+ connections, you will need to prepare a 120ohm resistor (to connect between the CAN high and CAN low wires.)

You don’t need to connect a 120ohm resistor if you use the MP001 connection.
