WARNING : Haphazardly applying voltage to certain circuits can cause
damage to a vehicle's electronic components. Therefore, it is strongly advised to
use the vehicle manufacturer's schematic and diagnosing procedure while
testing.

Fuel Injector Testing and Cleaning
Fuel Injector Testing
：
1.Connect the black battery clip of the Godiag GT103 Mini Pirt Electric
Circuit Tester to the negative electrode of the battery the red battery clip to the
positive electrode of the battery. If the lighting LED of Godiag GT103 Mini Pirt
Electric Circuit Tester is on, the power supply of the equipment is normal.
2.Connect the fuel injector test line to the fuel injector to be tested.
3.Press the fuel injector relay function button and the buzzer will beep once.
The function output green light flashes.
4.The control signal is sent to the plug of the fuel injector to drive the fuel
injector to open and close.
Note: If the pressing of the positive output causes a trip and open circuit, it
means that the tool has been overloaded.
The following reasons may explain it: The probe is directly in contact with
GND or the component you are testing is short-circuited.
If the positive output of the product is delivered to a high-current module or
component, it will cause the product to trip. At this time, reconnect the device
and it will function normally.
Negative circuit module and component circuit activation test. Find the GND
connection of the vehicle module according to the circuit schematic diagram.
After the probe touches GND, the foggy bi-color LED light should be red. The
buzzer makes a rapid sound,, and the function switch is pressed backward to
output the negative circuit to the probe. If the vehicle module or component can
work normally, it means that there is a problem with the GND wiring of the
module.
