Schematic Diagnosis and Troubleshooting 20 lectures 02:39:57 Power Side and Ground Side Switches preview Let's look at the similarities and differences of Power side and Ground side switches so we can understand them and later apply what we have learned to Information Circuits. Highlighting the Picture to Enhance Your Understanding In this video, I will show you how to highlight Power Load and Ground in three colors on the Power side and Ground side switch circuits from video nine. This will help make the expected voltage readings stand out on the page so you can enhance your understanding. Real World Diagnostic Considerations If the Battery voltage changes when the car is running, how will this affect the voltage reading we expect at different parts of the circuit? Let's take a look. Information Circuits The Module Information Circuits are often misunderstood. In this video, I will show you how they are very similar to the Power side and Ground side switch circuits that you already understand. Modules - Inputs and Outputs The Computer or Modules on the car are the decision makers for various systems on the car. This video explains how the Input circuits, Module Circuits and Output Circuits work together. Truck Release Schematic Explained The trunk release schematic in this lesson demonstrates the use of input, module and output circuits used on cars today. Trunk Release Schematic Highlighted Challenge time again.... See if you can highlight Power, Load and Ground for this Trunk Release Schematic. Download the schematic from the additional resources for this lesson. Trunk Release Schematic - Fault Number One The Trunk Release does not work. Let's do some schematic diagnosis and discuss how we would go about narrowing down the possibilities. Trunk Release Schematic - Fault Number Two Here is another Fault where the Trunk Release does not work. Put on your detective hat and let's start narrowing down the possible suspects. Trunk Release Schematic - Fault Number Three Let's use the diagnostic process again and see how we might reduce the number of steps necessary to complete the diagnosis. Cooling Fan Schematic Explained The cooling fan system for this lesson includes five power, load and ground circuits and has three relays. Let's see how it works. Cooling Fan Schematic - Off Position Highlighted Highlighting the cooling fan schematic in the Off position can go a long way to helping you understand how the circuits operate. Cooling Fan Schematic Highlighted - Low Speed This time let's highlight the cooling fan schematic with the fans in Low Speed. If you have not done so already, download the schematic in the additional resources. Cooling Fan Schematic Highlighted - High Speed One more time except this time let's highlight Power, Load and Ground when the fans are on High Speed. As we do our diagnosis in the upcoming lessons, you will see how important understanding the highlighting can be. Cooling Fan Fault - Low Speed Inoperative The Low Speed fans do not work, but the high speed fans do work. Let's look at the possible complaints we might hear from a car owner and see how we can diagnose the problem. Cooling Fan Fault - High Speed Inoperative This time the Low Speed fan works but the High Speed fans do not work. Detective hat time again. Let's see how we can narrow down the possibilities and find the culprit. A Little Bit About Scanners Can a scan tool help us more quickly diagnose the problem? Cooling Fan Fault - All Fans Inoperative None of the fans work this time. What do you think the complaint will be? How can we quickly narrow down the possibilities? Cooling Fan Faults - Reverse Psychology This video twists the diagnosis around to help you understand the schematic inside out. I call it reverse diagnosis. Before You Blame the Module and Next Steps This video provides a few tips to help you avoid a misdiagnosis when dealing with computers and modules.
