 Advanced Workshop Has Been Discontinued

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 Covers
Troubleshooting Auto/Truck Electronics
and Computer Control Circuits


Day 1 of Phase 3:
"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 3:
"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 3:
"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 circuit failure.
