2. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the scan tool, please read this user's manual carefully and observe the following safety precautions at a minimum whenever working on a vehicle:
- Always perform automotive testing in a safe environment.
- Do not attempt to operate or observe the tool while driving a vehicle, as this will cause driver distraction and could lead to a fatal accident.
- Wear safety eye protection that meets ANSI standards.
- Keep clothing, hair, hands, tools, test equipment, etc., away from all moving or hot engine parts.
- Operate the vehicle in a well-ventilated work area. Exhaust gases are poisonous.
- Put blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
- Use extreme caution when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
- Put the transmission in P (for A/T) or N (M/T) and ensure the parking brake is engaged.
- Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
- Do not connect or disconnect any test equipment while the ignition is ON or the engine is running.
- Keep the scan tool dry, clean, and free from oil/water or grease. Use a mild detergent on a clean cloth to clean the outside of the scan tool when necessary.
- The manufacturer is not responsible for any damage caused by unintentional or deliberate misuse of this product or tools.

4. Setup: Quick Self-Test
Before starting to test any circuit or components, it is crucial to confirm that your P60 device is in good working condition by performing a self-test. The P60 is powered through the car battery.
- Connect to Power: Connect the red battery clamp to the positive terminal of the car battery and the black battery clamp to the negative terminal of the car battery.
- Positive Voltage Test: Press the power switch forward. This will activate the probe with positive voltage. The display will light up red and show the current battery voltage. Release the switch, and the display will light up white.
- Negative Voltage Test: Press the power switch backward. This will activate the probe with negative voltage. The display will light up green, show 0V on the LCD, and the buzzer will sound. Release the switch, and the display will light up white, and the sound will stop.
If the device passes these tests, it is working properly and ready for use.
5. Operating Instructions
5.1. Voltage and Positive/Negative Detection
When the device is connected to the car's power supply, the display lights up white and the screen will show 0V. When the probe is touched to a positive circuit, the screen will show the current circuit voltage. If the device's power supply and the circuit being tested are separate, the ground lead of the device needs to be connected to the negative terminal of the circuit being tested. If the probe touches a negative circuit, the display will light up green, the screen will show 0V, and the device will emit a beep.
5.2. Diode Detection
Connect the ground lead to the negative terminal of the diode and the probe to the positive terminal of the secondary tube. When the diode icon appears on the display and a voltage value is shown, the diode is good. If the display does not respond or the screen shows green and the device beeps, the diode is faulty.
5.3. Component Activation
The activation function can be used to activate components such as the starter, fuel pump solenoid, blower, cooling fan, headlights, etc. Connect the grounding auxiliary clip to the negative terminal of the part, and the probe contact to the positive terminal of the part. Then, press the positive activation button (+). The probe will output a positive voltage, the screen will light up red and display the current activation voltage, and the part will be activated. The probe can output both positive and negative voltage. Press the (+) button for positive voltage output, and the (-) button for negative voltage output. The maximum activation output current is 8A. Equipment drawing more than 16A will trigger the trip protection function.
5.4. Continuity Testing
By using the probe tip and an auxiliary ground wire, continuity testing can be performed on wires and components that are disconnected from the vehicle's electrical system. When the continuity test is passed, the display lights up green and the unit beeps. Note: Do not press the activation switch during the continuity test.
5.5. Grounding Detection
Use the probe to make contact with the negative terminal of the component. When the ground test is passed, the display will light up green and the device tone will sound. Note: Do not press the activation switch during ground detection.
5.6. Test Trailer Lights and Connectors
Connect the device to the battery. Clip the auxiliary ground wire to the trailer ground. Connect the probe to the socket of the trailer connector, and press the (-) button to detect the function and direction.
5.7. Jumper Lead Function
The black clip and auxiliary ground wire are directly connected through the device. With the red clip and vehicle battery disconnected, the device can be used as a long jumper lead. Note: When using the device for jumper function, please pay attention to avoid short circuit and overload, as the jumper lead function is not protected by the device's circuit breaker.
5.8. Track and Locate Short Circuits
In most cases, a short circuit will manifest itself as a blown fuse or a tripped electrical protection device (such as a tripped circuit breaker). To trace and locate a short circuit:
- Remove the blown fuse from the fuse box.
- Use a probe to touch each fuse contact. The line that lights up green and beeps on the equipment display is the shorted line.
- Note the line number or color and follow the wire as far as possible to trace the harness.
- If you are tracing a brake light short circuit, first the harness must pass through the threshold of the wire. Find the color or number of the wire and mark it.
- If the display lights up green and a tone sounds, you have verified that the wire is shorted.
- Follow the wire to the exact location. Repeat this procedure in the direction of the short circuit until you find the exact location of the short.
6. Maintenance
To ensure the longevity and proper functioning of your Topdiag P60 tester, follow these maintenance guidelines:
- Keep the scan tool dry and clean.
- Ensure it is free from oil, water, or grease.
- Use a mild detergent on a clean cloth to clean the outside of the scan tool when necessary.
- Store the device in a safe place, away from extreme temperatures and direct sunlight, when not in use.
7. Troubleshooting
- Device not responding or showing incorrect readings during diode test: If the display does not respond or the screen shows green and the device beeps during a diode test, the diode is likely faulty.
- No voltage reading or incorrect ground detection: If the device's power supply and the circuit being tested are separate, ensure the ground lead of the device is properly connected to the negative terminal of the circuit being tested.
- Component activation fails or device trips: The activation output has a maximum current of 8A. If the equipment being activated draws more than 16A, the device's trip protection function will activate. Reduce the load or check the component for faults.
- Issues with Jumper Lead Function: When using the device as a jumper lead, remember that this function is not protected by the device's circuit breaker. Exercise extreme caution to avoid short circuits and overloads, which could damage the device or vehicle.
