Functions
1. Find The Short Circuits: In most cases, a short circuit will appear as a blown fuse or a tripping of an electrical protection device.Use the probe tip to activate and energize each of the fuse contacts..The contact which trips the circuit breaker is the shorted circuit.
2. Find The Bad Ground: Probe the suspected ground wire or contact with the probe tip. If the circuit breaker tripped, this circuit is more than likely a good ground.
3. Testing Trailer Lights: While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer ground , probe the contacts at the jack and then apply voltage to the probe tip. This lets you check the function and orientation of the connector and trailer lights.
4. Check Continuity: While the tool is in Resistance mode, using the probe tip with chassis is ground or the auxiliary ground lead, continuity can be tested on wires and components attached or disconnected from the electrical system of vehicle.
5. Activating Component: The component activation function is designed to generate activation signals to the tested components, such as activating lights, motors and other on-board electric equipments.
6. Signal Circuit Testing: Once you extract a DTC from the vehicle and realize that troubleshooting begins with some kind of sensor circuit, there is a quick test you can perform to verify the code. Testing your sensor is easy while using the tool.
7. Voltage and Polarity Testing: While the tool is in DC Voltage mode, contact the probe tip to a positive circuit. If contact the probe tip to an open circuit, neither of the LED will light.
