ELECTRICAL DIAGNOSTICS AND APPLICATIONS
Automotive Electrical Systems: This three-day course involves classroom study of electrical systems operation, component function and testing, wiring diagram and flow chart reading, use of diagnostic equipment and diagnostic strategies. Maximum allowable time is spent in shot troubleshooting using factory testing procedures.
Truck/Heavy Equipment Electronics Overview, and Wiring Problem Diagnosis: Strongly recommend completing 2-day "Truck and Auto Electrical Review and Sensor Diagnosis" class prior to this program. Electronics vs. electrical, wiring diagrams, problem solving, the application and testing of various diodes and transistors, computer circuitry and testing of computers. Wiring circuit faults and protection devices. Maintenance of computer/electronic systems.
AUTO ELECTRIC MULTIPLEXING: Multiplexing is a system where several signals may be sent through a single wire essentially at the same time. The advantages of this are substantial. Consider the weight reduction in wiring harnesses alone.
There is an interesting challenge here for Technicians in understanding how a multiplexer (MUX) can stuff all these signals into one end of a single circuit and extract them from the other end, sending them to the right components (DEMUX). Added to this is the ability to diagnose and troubleshoot these systems when they do not do what they are supposed to. The first portion of the program is spent in classroom covering electrical and electronic systems and multiplexing principles of operation. This is done through the use of power point presentation, wiring diagrams and components. This is followed by the practical portion at the vehicles. This includes component locating, use of scan tools and diagnostic equipment, data stream interpretation and diagnostics.
Heavy Duty Batteries, Charging, and Starting Systems: 12 and 24-volt systems. Emphasizes preventative maintenance. Battery construction and servicing, troubleshooting and testing. Charging system construction, service and testing. Starter construction, tests, service, and safety devices. System troubleshooting.
Electrical Review, Sensor Diagnosis, and Scan Tool Diagnosis: Lab-based program for 12 and 24V DC systems. Electrical laws and terms, measuring devices. Wiring diagrams and circuits, diagnosis, and troubleshooting.
Intermediate Advanced Electronic Scan Tools: This course is designed to enhance the technical expertise of mechanics, maintenance personnel, technicians, operators, and others who are associated with equipment maintenance.
Scan Tool Diagnosis for Electronically Controlled Automatic Transmissions:Basics and terminology. How computers communicate. Troubleshooting a "down" system, diagnosis. Pathfinder/troubleshooter use for Ford, General Motors, and Chrysler applications. 8 hours.
No-Code Drive Ability Diagnosis: Troubleshooting! Differentiating between a cause and a symptom. Unified diagnostic strategy- fuel and ignition. Computer, emission control and mechanical system diagnosis. Analyzing results and "tying it all together."
Allison Electronic Transmission: In this class, students will learn the theory of operation, identify inputs and outputs, scan data streams, and verify information, reprogramming the Allison Transmission and Troubleshooting techniques. 16 hours.
Fuel Injection - Ford or GM or Chrysler: Central and Sequential fuel injection, principles and procedures, inputs and outputs, ignition systems, troubleshooting and "tricks" with each system. 16 hours per manufacturer
