Today, the ballgame has changed. Electronic components can be deceiving and make you think everything looks good, and you end up asking yourself, “So where’s the problem?” Understanding how a circuit works will help you with a quick and accurate diagnosis and hopefully prevent changing out perfectly good parts.
When diagnosing a fault code, the best place to start is the “Circuit Description” section in the TruckSeries truck repair software. The information provided here gives you a description of the circuits involved, applicable sensors and components, specifications and how the circuit works. Reading this section along with viewing the wiring diagram for the applicable components will put you ahead of the game.
Wiring diagrams make it easy to see the path of a circuit. Now you have a basic understanding of how everything is supposed to work and a logical path to follow. Save yourself some time and frustration and take advantage of the information TruckSeries provides.
