They will learn fundamental laws of heat energy and heat transfer as related to HVAC systems and will use this knowledge to better understand refrigerant system operation, performance testing, and gauge-driven diagnostics as well as related service procedures, recovery, evacuation, and charging. Technicians will learn the components, operation, control, and diagnostics of the HVAC system. They will learn when, how, and why to use the various modes of a digital multimeter to isolate problems circuits plus additional resources including Parts Pro, Excelerator, EZWiring, and other DTNA resources. They will build series, parallel, and series parallel circuits as well as multiple circuits with relays and multiple controls for the purpose of understanding electrical circuit operation and problem conditions. Technicians will review electrical fundamentals as they apply to DC circuits. The class covers the power distribution thru the truck, the electronics, new datalinks, and goes thru the understanding of the wall charts.ĬVE12 ELECTRICAL TROUBLESHOOTING (4 DAYS)ĭesigned to guide technicians through a step-by-step process to understand and analyze electrical circuity, this course prepares technicians to understand schematic circuity diagrams and wiring harness drawings, learn best test points, and perform hands-on diagnosis and testing of DTNA vehicles. The CEEA class covers the Single SAM system that is used on the New Cascadia and new Western Star trucks. This professional level course will provide the technician with an in depth understanding of Common Electrical and Electronic Systems on the DTNA vehicles that utilize it. Course objectives include: inputs, outputs, and controls, J1708/1587, 1939, multiplexing, CAN networks, DiagnosticLink operation and interpretation, ABS systems troubleshooting, vendor and OEM circuits, and understanding the 7-step troubleshooting process.ĬVE06 CEEA+ COMMON ELECTRICAL AND ELECTRONIC ARCHITECTURE (3 DAYS) Technicians gain an in-depth understanding of each system including location of system components, how the system and components communicate, essential troubleshooting skills, electrical diagnostics, and the use of MID’s, SID’s, PID’s, and FMI’s for diagnostic purposes. They will learn specifically how sensors work and how to confirm proper operation of various sensors including speed sensors, temp sensors, position sensors, pressure sensors, Hall effect sensors. Technicians will learn how state-of-the-art electronic control systems on today’s medium and heavy-duty trucks generally work including how ECUs monitor a variety of sensors, determine appropriate actions, and control outputs. Systems covered include: main and cab air suspension systems and adjustment, clutch and linkage operation and adjustment, power steering systems, wheel ends, air supply and delivery systems, and air brake systems. Additionally, technicians will learn the operation, troubleshooting, and repair of many main mechanical systems on heavy-duty vehicles. By learning the correct way to approach vehicle maintenance, technicians can avoid common pitfalls that cost the technicians and dealerships time and money. In this course, technicians will learn to access and use the DTNA and vendor service literature that underpins all troubleshooting and repair efforts. This course is the foundation of the Service Training Academy vehicle training curriculum.
