Basic Knowledge Required

To use this most effectively, a general understanding of basic electrical circuits and circuit testing tools is required. One should be familiar with wiring diagrams, the meaning of voltage, ohms, amps, the basic theory of electricity, and understand what happens when a wire opens or shorts.

To perform system diagnosis, the use of a diagnostic Scan tool is required. A 12 volt test light, digital volt ohmmeter with 10 megohms impedance, vacuum gauge, and jumper wires are also required. Please become acquainted with the tools and their use before attempting to diagnose a vehicle.
