- Basic Knowledge and Tool Requirements

Basic Knowledge Required

You must be familiar with some of the basics to use this section of the database. They will help you to follow diagnostic procedures in this section.


Basic Electrical Circuits

You should understand basic electricity and know the meaning of voltage (volts), current (amps), and resistance (ohms). You should understand what happens in a circuit with an open or a shorted wire and you should be able to identify a shorted or open circuit using a DMM. You should be able to read and understand a wiring diagram.


Use Of Digital Multimeter (DMM)

You should be familiar with the Digital Multimeter (DMM), particularly essential tool J 39200. You should be able to use the meter to measure voltage (volts), resistance (ohms), current (amps), capacitance (farads), intermittents (min/max) and frequency (Hertz).


Use Of Circuit Testing Tools

You should only use a test lamp when a diagnostic procedure refers to it's use. You should know how to use fused jumper wires to test components and allow DMM readings without damaging terminals. You should know how to use Connector Test Adapter Kit, J 35616 and use it whenever diagnostic procedures call for front probing any connector.
