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.
7.）The Module Test Demonstration
Fuse test, battery voltage test, vehicle LAN circuit test, Hall sensor
performance test, real electricity virtual electricity test, ignition pulse signal test,
throttle voltage signal test, crankshaft sensing, camshaft sensing, speed signal.
8.）Fuel Injector Testing and Cleaning
Fuel Injector Testing：
1.Connect the black battery clip of the GODIAG PIRT Power Probe to the
negative electrode of the battery the red battery clip to the positive electrode of
the battery.
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. The ammeter shows the working current of the fuel
injector.
If the fuel injector is driven to open and close, the current shows a normal
value, indicating that the fuel injector under test is normal.
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 red LED light should light. The buzzer makes a
rapid sound, the voltmeter displays the current voltage, 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.
