CarTrain "Electronic brake control systems ABS/TCS"
"Electronic braking control systems ABS/TCS" are a key point for training in service, repair and diagnostics. Vehicle safety has taken on ever increasing priority in recent years. Functional understanding and diagnosis of electronic brake systems are becoming more and more important in practice. The interaction of sensors and actuators via control systems and controlled systems is very complex. On the training system, signals are recorded and evaluated by means of measurement and testing. Based on the customer's description of problem symptoms, trainees work with circuit diagrams and functional design plans to apply the practical diagnosis of faults and malfunctions in vehicles and systems. Measurements are taken with the integrated measurement interface or with every other suitable measurement instrument typically found in the workshop.
