Onboard Diagnosis II Simulator

This course demonstrates how to read out emission data with the help of the onboard diagnosis unit (OBD II or EOBD), interpret the data and use the results as a basis for eliminating systemic faults. Students have the possibility to adjust various parameters on their own to see how these settings affect the tester. They also have the opportunity to tap the CAN transmission signal to display it on the oscilloscope.

OBD II Simulator with CAN Interface and Scan Tool

This OBD II simulator can be used for simulating exhaust gas data. Potentiometers allow for sensor data, such as speed or rev-count sensors, to be altered “during travel”, so to speak. In addition, buttons are provided to simulate faults in the vehicle, which leaves a fault entry in the electronic control unit and causes the malfunction indicator light to display. The relevant button can then be used again to cancel these functions in the tester. In this way it is possible to practically analyse test conditions in a much easier fashion than on a full-scale vehicle, as the latter would mean physically manipulating the electrical system of the vehicle itself.

Power Supply

Power Supply, 13.5 V, 45 A

The "Power supply" module is part of ´various training systems including the "Modular engine management" system. It provides power to various components in a similar to the way they are supplied in practice in a real engine by means of a 12 V battery. The module employs a 600 watt power unit which can supply a maximum current of 45 A at 13.5 V between its screw terminals. To protect the training system, a maximum current of 30 A can be tapped via the 4-mm safety sockets. This protective function is implemented by electronic monitoring of the 4mm safety sockets. Thanks to the high-resolution printing on the front panel, the module can immediately be identified as a typical car battery.

Technical highlights:

• Stable on-board network voltage of 13.5 volts
• Automatic cut-out without fuses
• Short-circuit protection
• Typical appearance of a vehicle battery thanks to high-resolution printed image of a starter battery
• Maximum current: 45 A

Technical details:

• Operating voltage: 90-264 V AC (47-63 Hz)
• ​Dimensions: 297 x 227 x 180 mm (HxWxD)
• Weight: 1.6 kg
