The entire vehicle network on a single panel: eleven control units in their original positions, four bus systems (LIN, CAN-B, CAN-C, FlexRay) interconnected, and a functional speedometer display that visualizes the effects. Over 50 switchable fault scenarios—reproducible for exams and tests. Plus an integrated diagnostic tester with fault memory: read, measure, isolate, repair—and confirm in diagnostic input mode that the fault is gone.
What the trainer does in class — shown in a minute, with sound. Subtitles can be switched on in the player.
Instead of individual bus nodes, the trainer displays the entire vehicle electrical system of a modern vehicle—from the battery to the engine control unit, from the door module to the gateway. All loads and control units are shown in their actual positions within the vehicle on a 399 × 297 mm front panel.
What previously required several trainers, the 4.0 accomplishes in a single unit—and at a depth that was previously impossible in the vocational school workshop.
Complete top-down layout with eleven control units in their original positions—gateway, engine, ABS, comfort modules, doors, sensors. Four bus systems interconnected. The speedometer display shows the real-time effects at a glance.
ECU faults (terminals 30/31), CAN isolation faults (high/low interruption, short to positive/ground), FlexRay isolation faults, LIN bus issues, power supply. Can be activated via the software control panel. Reproducible for exams.
The eleven control units behave just like they do in a real vehicle—same response to malfunctions, same trouble codes. Diagnostics using multimeter, an oscilloscope, and a tester, just like in everyday workshop operations. Separate D-Sub connectors for each bus.
Activated via the software control panel. Can be set to exam mode or free practice mode. Six error categories cover the vehicle electrical system, all four bus systems, and the power supply.
Terminal 15, 30 or 31 without voltage or ground — at the gateway, engine, ABS, body control unit, door module and sensors. Plus two simulated control unit defects that overload the CAN or FlexRay bus. Trainees measure the supply and isolate the fault.
Comfort-CAN: High/Low interruption, short to positive, short to ground, crossed. Monitor single-wire mode. Measure H/L signals with an oscilloscope.
Drive CAN: Same error patterns as CAN-1, but affecting the engine, ABS, and FxR bridge. Communication is lost — the speedometer reads 0.
FxR-A and FxR-B can be switched separately: BM/BP interruption, short to positive/ground, crossed. Static signal or no signal—readable directly on the speedometer.
Short to Plus/Ground (with and without a resistor), interruption before A39 or before B40, contact corrosion. Observe master-slave behavior.
System Voltage Low: different voltage levels at battery B36. Trainees measure the voltage directly at the battery and isolate the supply fault.

The TP-Lab Network Diagnosis 4.0 is the cornerstone of the Network Path. It covers all three levels and is suitable for both the beginning (Bus Basics) and the in-depth diagnostic phase.
The TP-Lab Network Diagnosis 4.0 includes a comprehensive 24-hour curriculum with 51 worksheets and an accompanying E-Learning course. Teachers guide students along a learning path—trainees learn independently, even outside of workshop hours.
The TP-Lab Network Diagnostics 4.0 comes with a complete course on TPGO. It runs in the browser — tablet, phone, computer. The tasks walk through the same measurements the apprentice takes on the trainer: first the assumption, then the series of readings, then the comparison.
