Electronics 101 Hands-On

Today’s vehicle is loaded with advanced electronic control systems and computers. In

order to repair these electronic machines, you need an in-depth understanding of

electronics and how to diagnosis and repair them. This hands-on class will cover the

operation and testing of basic to advanced electronic circuits. Each tech is provided

with their own advanced ATS electronic engine simulator to utilize during the class.

The engine simulator provides live circuits with hundreds of faults. This class starts out with basic

circuits and moves into to advanced circuits with troubleshooting tips and tricks.

Regardless of your skill level this class will take you to the next level.

Circuits that will be covered in-depth include:

Series circuit testing Parallel circuit testing Series-parallel circuit testing Lamp circuits Motor relay circuits Throttle position sensor circuits Engine coolant temperature sensor circuits Crankshaft position sensor circuits Camshaft position sensor circuits fuel injector circuits Ignition coil circuits Oxygen sensor circuits

Crankshaft to camshaft (crank angle space) circuits Front O2 to rear O2 catalytic converter testing

Techs will need to bring their scopes and low amp clamps. Make sure that your scope is operational

with all 4 leads attached. Electronics are all about timing so be ready to learn how to utilize multiple

scope traces at once. This is needed in order to evaluate the operation and timing of circuits in the

modern vehicle.

If needed, we can supply a limited number of ATS ELITE4 oscilloscopes. Please let us know

when signing up.

This class covers how to best use the oscilloscope. Many technicians just don’t understand

what the scope is showing them. The scope is a powerful tool that will change the way you

diagnose electronic systems in your service bay. Start making real money with your diagnostic

time.

The scope is the way to see what is really happening in the electronic system, allowing quick

accurate diagnostics in your service bays. There are two ways technicians diagnose vehicles;

the first is an educated guess where parts are put on until the problem hopefully goes away.

The second is using an oscilloscope where the circuits can accurately be analyzed and the

cause of the problem is repaired or replaced. If you are going to stay in the automotive repair

business, this class is a must.

This provides you with advanced hands on training. It will provide you a good understanding

of electronics and computer control systems as well as oscilloscope fundamentals.

Basic Electrical Hands-On

ATS developed individual electrical simulators will be used during class. This allows

each technician to have a trainer that produces electric and electronic signals that will

be captured with a DVOM. The student will learn advanced diagnostic techniques to

use meters, oscilloscopes and amp clamps. The student will need to bring their meter

with leads and an amp clamp.

Circuits that will be covered in-depth include:

Series circuit testing Parallel circuit testing Series-parallel circuit testing Lamp circuits Motor relay circuits Introduction to oscilloscope

This class can be customized and can include new meters for each technician at a special price. Any customization needs to be discussed and arranged in advance of class. Customization can include tailoring this class for basic or more accomplished users.

The Pressure Is On

Every decade or so a new automotive technology is discovered that is truly game

changing. The use of pressure transducers in automotive service bays is one of the

most exciting discoveries of the 21st century. This innovative technology saves repair

shops time and money on a grand scale. This technology can be used to quickly test

the engine’s mechanical condition. This class uses case studies with live pressure

waveforms to demonstrate how to use this advanced technology. This course covers

advanced technics to quickly find:

Use of the scan tool to understand how to identify if the misfire is mechanical,

electrical or electronic

Identify which cylinder(s) is misfiring using tailpipe pressure and CKP signal

waveform analysis

Decoding Control Area Network (CAN)

Communication has been essential from the beginning of history. In the modern

automobile, communications are vital in order to control the on-board systems within the

vehicle. The first electrical data communication was Morse code, where on-off signals

were timed to provide information that would be sent on a wire. This basic idea of on

(high) - off (low) signals is still the main way on board vehicle communications send and

receive communications. This class covers how the Control Area Network (CAN)

works, how to diagnose the CAN system and how to properly repair communication bus

problems. With many real world case studies, you will learn how to quickly diagnose this

advanced communication system where it counts; in your service bays.

Analyzing Ignition Waveforms

The spark ignition (SI) engine has been around for over a hundred years. The ignition

discharge has been a way for the technician to see what is happening within the

combustion event occurring within the cylinder. For decades, this was the main

diagnostic means for drivability issues. With the advent of the modern scan tool, the

technician has gotten away from this very important method. This class will take an in-

depth look into the ignition system. Learn how to use these waveforms to quickly

diagnose the SI internal combustion.

will take an in-depth look into vibration and noise and address how to correct these

problem vehicles.

Crankshaft Sensor & Camshaft Sensor Diagnosis

The Otto Cycle engine has two complete crankshaft revolutions to complete the four

engine strokes. Therefore the use of just one sensor on the crankshaft would not

provide the necessary data to calculate which of the engine strokes the engine is

currently on. As the crankshaft rotates, it moves the piston toward the cylinder head

until it reaches the Top Dead Center (TDC) point. It then moves the piston away from

the cylinder head until it reaches the Bottom Dead Center (BDC) point. The use of one

sensor can only indicate if the piston is at TDC or BDC. It cannot differentiate which of

the four stokes the engine is on. Therefore a second sensor, camshaft sensor, must be

used in order to locate crank angle space. Crank angle space is where the particular

engine stroke that the engine is currently on (intake, compression, power or exhaust)

can be identified. This class will provide an in-depth understanding of how these

sensors are used and how to properly diagnose these circuits.

This course covers:

CKP misfire

Variable reluctance sensors

Hall effect sensors

Magneto resistive element sensors

the process of leak detection. Additionally, the pros and cons of the tools and

equipment used in leak detection are covered. Learn new diagnostic techniques on

how to locate the leak quickly and accurately, saving serious aggravation and hours of

diagnostic time.

______________________________________________________________________

No Code Drivability

The words, “no code drivability” can send a shivering fear clear through a technician

and the words, “intermittent no code drivability” are even worse. A technician can

hope that the symptoms of a no code drivability problem are a pattern failure, but what if

the they’re not? Even with known symptoms and codes, the associated pattern failure

may be a different problem. The question is; how does a technician correctly

troubleshoot coded or non-coded drivability problems? The process is actually very

similar for both. This class covers how the vehicle’s computer is programed and the

thought process for proper diagnosis.

This course covers:

Complete circuit operation and waveform analysis

Throttle position sensor circuit waveform analysis

Throttle by wire circuit operation

Injector waveform diagnosis

quality concerns increased, the auto emission regulations also increased. These new

regulation brought about the introduction of the catalytic converter. Today, the

automobile tailpipe emissions are at an all-time low. This is due impart to an

engineering approach where the system, as a whole, is designed around the catalytic

converter. Learn how the catalytic converter is made and how to accurately diagnose

these components quickly.
