Each switch, three states
No fault · Broken wire · Contact resistance or short circuit. With 22 switches, this results in significantly more fault scenarios than the number would suggest.

The difference in diagnostics
Wired in series. Not just tapped in parallel.
The breakout box is connected directly to the control unit; the wires run through test sockets there, many of them through 4 mm bridge plugs. The components carry pin-outs. You measure the signal at the control unit and at the component, open the line and test it – and measure current right in the panel. That is full diagnostics.
Fault in the wire, connector, component – or the control unit?
1 · At the control unit: 4.8 V – the control unit delivers.2 · Fault switched on – at the component pin-out: 0 V.3 · Bridge plug pulled, box ↔ pin-out tested: wire open.4 · Ammeter instead of bridge plug: current right in the panel.
- 01Measure at the control unit
The breakout box sits directly at the control unit: here you see the signal it outputs – e.g. 4.8 V.
- 02Measure at the component
Measure at the component pin-out. If 0 V arrives there, the fault is between box and component.
- 03Open and test the line
Pull the 4 mm bridge plug and test the wire from box to pin-out with an ohmmeter: open – fault located.
- 04Measure current
Where a wire runs through a bridge plug, an ammeter simply replaces the plug.
Parallel tapping systems are simpler to build – and cheaper. But they only show that a fault exists, not where. Only a breakout box at the control unit plus pin-outs at the component enables full diagnostics – voltage, continuity and current on every wire with a bridge plug.
Why this trainer
What it does in the classroom.
Four points where the TDI Training Engine differs from a diagram — you measure on the trainer, not on the drawing.
Diesel, with its own sizes
High pressure, boost pressure, air mass, and exhaust aftertreatment on a running engine—the diagnostics required for a diesel engine, not those for a gasoline engine.
Measuring on the component, not on the equivalent circuit diagram
Approximately 80 measuring sockets located directly on the components, in the colors of the original schematic; occupied control unit pins can be opened circuited individually.
Your existing equipment comes along
With TPGO, the courses are also compatible with your existing THEPRA devices—so your current equipment remains in use. Anyone who purchases a 4.0 device with TPGO today will also be able to use it with the older trainers in their facility.

E-Learning · TPGO
The course for the trainer.
On every screen.
The TDI Training Engine 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.
