GODIAG GT101 PIRT Power Probe Review and Use Tutorials

What is Godiag GT101 PIRT Power Probe?

-A special circuit maintenance testing tool

-To diagnose an open circuit, short circuit, detect positive and negative circuit and pulse current of power lines

-Test lighting lamp, window lift motor, horn, ECU control Unit power supply and other individual component, vehicle component circuit.

-Detect relays and fuel injectors as well as the cleaning of fuel injectors.

-The output current can be reversed to form a loop power, and when the current exceeds 20A, it automatically trip to protect the device and extend the service life.

-Detect all 0-80v electronic systems, greatly shortening the detection time.

How to use Godiag GT101 PIRT Power Probe?

Images + words on how to use Godiag GT101 PIRT Power Probe:

Turn on Godiag GT101

Firstly, connect the power supply, clamp the black clip to the negative, and the red clip to the positive, then the device can successfully turn on. then, install the probe.

Self-Test:

1.Connect the device to the car battery.

2.Connect the probe pin to the positive electrode of the battery, and the red LED light should be on. The buzzer makes a rapid sound, and the voltmeter displays the current positive voltage.

3.Connect the probe pin to the negative terminal of the battery, and the green LED light should be on. The buzzer makes a low-frequency sound, and the voltmeter displays a voltage of 0.00V.

Output Current:

Clamp the negative of the bulb with a clip at the end of the GT101, hold GT101 upward and press the switch to output positive electricity and slowly close the probe to the positive of the bulb, then the bulb will light up.

Relay Test:

Relay Connection in 3 methods:

1）Conventional Relays

Relay port 86, Positive power supply (red), 85 power supply negative (black), 30 COM (yellow), 87 Normally Open (green),87a Normally Closed (blue)

2）Special Relays

Relay port 1. Negative power supply (black), 2. Positive power supply (red),3. COM (yellow), 4. Normally Closed (blue), 5. Normally Open (green)

3）Other Relays(port definition is not specific)

Users define the connection according to the port of the relay.

Relay Test Procedures

Prepare relay test leads and connection adapters.
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.
Connect the black battery clip of GODIAG PIRT Power Probe to the negative electrode of the battery and the red battery clip to the positive electrode of the battery. If the GODIAG PIRT Power Probe displays normally, and the illumination LED lights it means that the power supply of the equipment is normal.
Press the function button of the fuel injector relay and the buzzer will beep once. Function output green light flashes .
The relay test signal is transmitted to the relay test line and the relay adapter to drive the relay to work. The ammeter shows the working current of the relay.

Result Judgment:

A.For relays with normally open and normally closed functions, the red power light on the relay adapter flashes; for the normally open, green light flashes; for the normally closed, the blue light flashes. The current displays normal current value.

B.For relays with only normally open function, the red power light on the relay adapter flashes; for the normally open, the green light flashes; for the normally closed, the blue light goes out. The current shows the normal current value.

Fuel Injector Test :

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.
Connect the fuel injector test line to the fuel injector to be tested.
Press the fuel injector relay function button and the buzzer will beep once. The function output green light flashes.
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.

Fuel Injector Cleaning:

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.
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.
Connect the injector test line to the injector that needs to be cleaned.
Press the fuel injector relay function button and the buzzer will beep once. The function output green light flashes.
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.
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.
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.)
