Features:
Trainer testing electrical and electronic systems used in modern automotive technology
This trainer is real equipment built with genuine automotive components.
Learning objectives :
-Analysis of the braking system in case of skidding on one or more wheels with out ABS control.
- Analysis of the braking system in case of skidding on one or more wheels with ABS control , in relation to : different friction loads , equal wheel
speeds, different wheel speeds
-Checking the condition of intervention of the solenoid valves of the electro-hydraulic set, in the following cases : smooth braking without,
skidding, braking with skidding of a front wheel and braking with skidding of a front wheel and braking with skidding of a rear wheel
- Analysis of the waveform of the driving signal on solenoid valves
- Analysis of the waveform of the signal coming from the sensors of angular velocity.
- Analysis of the pressures acting in tandem circuit and of the depressions in the brake booster .
- Analysis of irregularities, operational defects and faults :
Insertion of non destructive faults by means of microprocessor fault simulator
Fault-finding methods with traditional instruments or special instruments
Data gathering and reading, signaling of malfunction conditions, fault location by guided diagnosis and information upon operator's request,
given through diagnostic tester
