General Description Information

Before attempting to diagnose the Continuously Variable Road Sensing Suspension (CVRSS) system, you must have a good understanding of electrical system basics and the use of testing tools. Without this basic knowledge, it will be difficult to use the diagnostic procedures detailed in this section.
^ Basic Electrical Circuits-You should understand the basic theory of electricity, series and parallel circuits, and voltage drops across series and parallel resistor systems. You should know the meaning of volts (voltage), amperes (current), and ohms (resistance). You should understand what happens in a circuit with an open wire or a wire shorted to ground or battery. You should be able to read and understand a wiring diagram.
^ Use of Circuit Testing Tools-You should know how to use a Digital Multimeter (DMM) to measure voltage, current, and resistance. Be aware that when DMM use is requested, the first terminal listed in the check is intended to be connected to the positive (usually red) DMM lead. You should know how to use jumper wires to test circuits.
