The EB-563 training system uses four stepper motors to simulate the four rotating wheels of a car. One wheel is equipped with an inductive sensor and three wheels are equipped with a Hall effect device. These sensors supply the Electronic Control Unit (ECU) with the current speed of each wheel in order to detect wheel slip. The speed and slip for each wheel is displayed on a large LCD control display unit. The student can simulate various driving conditions by pressing on the brake and accelerator pedals. The operation of the hydraulic modulator is shown by a graphic reproduction on the panel. The unit has a built-in stopwatch and elapsed distance displayed on the LCD to aid the students in performing experiments. Faults are inserted through the PUZ-2000 and are interactive with courseware. Diagnostic tests are performed on the standard 35-pin ABS wiring harness plug with a standard DMM and the built-in diagnostic test box. Students will also use an oscilloscope.
