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

Using amperage waveforms to diagnose electrical circuits is certainly not new. Technicians are routinely faced with the need to utilize an inductive amp probe to measure current. Proper diagnosis depends on not only operational knowledge of the amp probe, but a thorough understanding of the circuit being measured. In this course, CTI will revisit tips and techniques we have discussed in many of our diagnostic courses as well as introduce new techniques such as using a micro amp probe to diagnose circuits such as reference voltage and wide band air/fuel sensors.

Push button start/stop systems are almost standard equipment in today’s vehicles, but they still present a diagnostic challenge when problems arise.

This course covers the operation of the components involved and how to analyze them most effectively to make a confident repair. Topics include: • Push button start/stop system operation • Explanation of interior and exterior localization • Effective use of scan tool data for analysis • Importance of on-board wireless communications • Fob operation and programming

This is the first class in a series focused on chassis and alignment. One of the most important tasks required of any technician is the inspection. When it comes to steering and suspension components, it is vital that an inspection is performed correctly and completely. During this class, we will discuss the design and operation of steering and suspension systems and provide examples and procedures for proper component testing. Common failures and specific problem areas will also be discussed. Specific replacement tips provided in this class will expose many steps that cannot be skipped during the repair. These tips focus on the success of the repair and customer safety, as well as returning the vehicle to proper operating condition. This class provides answers to these questions: • How does the system operate? • How do I test the component properly? • How do I know when a component needs replacement? • When is it required for the component to be replaced before proceeding with the alignment? • Do I need special tools to do the job right?

With a conventional camshaft, all the variables that determine valve timing, lift, duration and overlap are cast in stone the moment the lobes are ground. Variable Camshaft Timing (VCT) or otherwise known as Variable Valve Timing (VVT) was then developed in order to achieve better overall versatility in a wider RPM range and various operating conditions by phasing the camshaft. Camshaft phasing systems allow the valve timing to be adapted to the respective operating conditions of the engine. With completion of this class technicians can expect to gain a deeper understanding of: • Camshaft foundations and the benefits of Variable Camshaft Timing (VCT) • Design and function of many modern VCT systems • Operation of various phaser styles • Special tooling requirements Variable Displacement oil pump technology • Testing of sensors, actuators and mechanical components of the VCT system • Scan tool data analysis and waveform diagnostics

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.

This class covers modern vehicle network operation and how to efficiently diagnose them using common tooling. The overwhelming majority of network related issues do not require decoding of individual packets of data. It is important to understand how a network exchanges information, but a deep dive into the bits. bytes, nibbles and ticks of each network is not needed to repair the vehicle. Knowledge of the network type, the expected voltage levels, and the layout of the network wiring to the modules can provide us with enough information to gain diagnostic direction. At that point, we can use our available tooling to determine the root cause of the problem. Topics Include: • Understanding common automotive networks and where to get help if we don’t understand them • Discuss OE and aftermarket scan tool communication benefits and challenges • Learn how to develop a logical diagnostic approach using service information and our own tooling • Understand diagnosis through communication related case studies
