Relay Test Procedures
1.Prepare relay test leads and connection adapters.
2.According to the characteristics of the relay, customers can distinguish,
the coil end of the relay, the common end, the normally open end and the
normally closed end. Connect the relay.
Manual Cleaning of Fuel Injectors：
1.Prepare a fuel injector cleaner pressurized can or a carburetor cleaner
pressurized can(nozzle diameter of the pressurized cans : 4mm). Connect the
fuel injector and manually clean the connector.
2.Connect the black battery clip of GODIAG PIRT Power Probe to negative
electrode of the battery and the red battery clip to the positive electrode of the
battery. If GODIAG PIRT Power Probe displays normally, and the 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. The function output green light flashes.
5.The control signal is sent to the fuel injector plug so as to drive the fuel
injector to open and close. The ammeter shows the working current of the fuel
injector.
6.Hold the manual cleaning tool tightly with your hand, and firmly fix the
fuel injector with your fingers to prevent the pressure of the cleaner can from
washing away the the fuel injector.
7.Clean the fuel injector under GODIAG PIRT Power Probe program.
(Note: Pay attention to the hazards of liquid to human body during manual
cleaning, and take protective measures. Do not operate in dangerous places
with open flames because the pressurized cans are extremely flammable.
Choose an open place to facilitate the discharge of cleaning liquid.)
