Four wheel drive (4WD) in itself is not a new concept. Original systems use a mechanically controlled transfer case with the associated driveshafts and axles. Today we see complex hardware design, electronic controls and advanced diagnostic techniques. New systems rely on input sensors, computers, electric motors actuators and data busses to operate. It is crucial to understand the function of all components and how they interact to diagnose problems efficiently.Topics in this course include: • Hardware construction and operation • Control systems and sequencing • Diagnostic routines• Component testing • Common failures • 4 hours

Today’s SUVs, sedans and sports coupes are embracing all-wheel drive to improve vehicle handling and, in some cases, make better use of high torque/high horsepower powerplants. Don’t confuse all-wheel drive with four wheel drive. Although some components are shared between the technologies, all-wheel drive utilizes advanced software and controls to precisely control torque vectoring and aid in the stability of the vehicle. Repairing these vehicles requires not only an understanding of the hardware, but also electronics and control strategies. Topics in the course include: Differences between AWD design vs. 4WD The role of software’s role in AWD operation Common AWD components and how they operate Proper diagnostic testing procedures Analysis of vibration issues

The automotive cooling system has gone through many design changes throughout the years. Metallurgy in the engine, radiators, water pumps and thermostats have all advanced. Many systems use multiple water pumps, multiple thermostats and some thermostats are electronically controlled. Electric water pumps are controlled by the powertrain control module to vary the flow. Many more coolant types exist today than ever before making coolant identification and coolant testing difficult. Coolant heaters have been added to some hybrid and electric vehicles to warm the high voltage battery up in cold conditions and coolant chillers have been added to cool the battery down in hot conditions. Cooling system bleeding techniques vary between manufacturers and models. It’s time to bring cooling system training in your shop. Topics in this course include: Coolant chemistry Coolant inspection and testing Coolant system service Water pump variants and flow control Heat exchanger operation Multi loop systems Cooling fan control

Una prueba de manejo no tiene la intención de aislar fallas que puedan estar causando un síntoma o preocupación. El propósito de una prueba analítica es simplemente recopilar información. Luego, una vez que se ha analizado la información que ha reunido, puede determinar la prueba o las pruebas adecuadas para reducir el problema a un sistema o subsistema de vehículo y, finalmente, diagnosticar con precisión la causa raíz de un problema. Esta clase examinará varios ejemplos de datos de escaneo capturados de vehículos GDI. Esta información evaluará rápidamente la condición del sistema de gestión del motor, verificará el funcionamiento correcto o encontrará pistas que dirigirán las pruebas de intrusión puntuales de manera eficiente. Independientemente de si el problema es impulsado por DTC o por síntomas, un ciclo repetible de conducción de prueba determinará si la causa raíz está relacionada con el aire (VE), relacionada con el combustible o relacionada con la adaptación.

The modern transmission can be very difficult to diagnose properly without an understanding of the wide range of inputs and strategies that make up transmission control. Diagnostic analysis of the transmission must take into consideration the mechanical aspects of the transmission, as well as the electrical, hydraulic and engine control influences. Many transmissions have been unnecessarily replaced when testing routines skip one of these factors and many repeated transmission component failures have occurred when the root cause of mechanical failure was not determined during the initial diagnosis. Some OBD II technicians may say, “That’s why I stay away from transmissions, I have enough to worry about with the engine drivability problems.” Many transmission technicians would also say the very opposite, however, the engine and transmission inputs and software strategies tend to overlap at a much higher level than ever before to control emissions, torque and driving experience. In order to be successful in either case, the blending of emissions control and driving experience forces both the engine drivability technician and the transmission technician to cross the long-time established border line between the two repair fields.

The expansion and use of multiple on-board control units that communicate with each other in one or more networks in the vehicle has become complex.

A test drive is not intended to isolate faults which may be causing a symptom or concern. The purpose of an analytic test drive is simply to gather information. Then once the information you have gathered has been analyzed, you can determine the proper test or tests to perform in order to narrow down the problem to a vehicle system or subsystem and eventually diagnose the root cause of a problem accurately. This class will examine several examples of captured scan data from GDI vehicles. This data will quickly assess the condition of the engine management system, verify correct operation, or find clues that will direct intrusive pinpoint tests efficiently. Whether the problem is DTC driven or symptom driven, a repeatable test drive cycle will determine if the root cause is air (VE) related, fuel related, or adaptive related.
