Auto/Truck Advanced Electronics Hands-On
This workshop has been discontinued.
If you would like to purchase a set of the training circuit boards call Vince at 972.276.9642.
You can practice troubleshooting sensors,
sensor circuits, the correct way to use DTCs, perform Critical
Voltage Analysis of sensor information, troubleshoot computer
control of actuators, actuator troubleshooting, study a wide
range of internal computer circuits, trace signals in digital
electronic circuits used in vehicle computers, learn how computers
work, learn how an actuator can smoke a computer driver circuit
- what you can do about it and much more!
Phase 3 Workshop (3-Days)
"Troubleshooting Auto/Truck Electronic Circuits
and Computer Control"
Day 1 of Phase
"Is the problem a bad sensor, bad wiring or a bad computer?"
Day 1 covers a review of DC voltage, AC
voltage and digital, pulse and PWM signal terminology. Passive
and active electronic component terminology is covered in today's
electronics language. Then we discuss computer principles and
computer "personality." Technicians study sensor circuits,
how sensors interface with internal computer circuits and how
sensor information (signal) is used by the computer. Analog sensor
circuits studied are 3-wire (TP), 2-wire (ECT) and 02 sensors.
Learn to distinguish between a sensor failure or a computer sensor
circuit problem. Learn how computers can set a DTC indicating
a bad sensor when the sensor is actually good. Technicians troubleshoot
TP, ECT and O2 sensor problems and problems in ECM/PCM internal
computer sensor circuits.
Day 2 of Phase
"Has the computer been damaged by a bad actuator or did
the computer fail by itself?"
Day 2 covers diodes, diode operation, diode
applications and testing diodes. We build on that by discussing
transistors, transistor operation, transistor applications and
testing transistor with an analog ohmmeter and diode test. You
will learn how LEDs work. Next, we discuss switch input circuits,
how they work, how the computer processes the information and
how to troubleshoot switch input circuits. Then follows troubleshooting
problems in switch input circuits. Next we discuss NPN and PNP
transistors in circuits and important facts you glean from schematic
diagrams. This is followed by ECM/PCM transistor circuit troubleshooting
exercises to identify soli-state circuit failures.
Day 3 of Phase
"Practice Troubleshooting Computer Control Systems"
Day 3 covers Integrated Circuits (ICs)
and reading schematic diagrams containing ICs in complete circuits.
Logic gates and truth tables are briefly explained. Technicians
trace digital signals in digital circuits using a Digital Logic
Probe (one is provided). This is followed by several troubleshooting
exercises combining all circuits taught up to this point including
troubleshooting transistor circuits in the ECM/PCM that control
actuators (solenoid and relay) to determine if the failure was
caused by an actuator failure or simply was a computer driver
