fuel injector and manually clean the connector. 

2.Connect  the  black  battery  clip  of  Godiag  GT103  Mini  Pirt  Electric  Circuit 

Tester to negative electrode of the battery and the red battery clip to the positive 

electrode  of  the  battery  .  If  Godiag  GT103  Mini  Pirt  Electric  Circuit  Tester's 

illumination LED lights, it means that the power supply of the device is normal.

3.Connect the injector test line to the injector that needs to be cleaned.

4.Press the fuel injector relay function button and the buzzer will beep once.
