  • technical details

The fault panel allows an instructor to simulate numerous types of hybrid failures. The panel consists of twenty rocker switches wired into various vehicle operating systems. Each switch has the ability to create a failure due to an opening within the circuit for that switch. When the switch is in the fault position, the hybrid system will set a trouble code that the instructor may use to diagnose the problem.

The fault panel has twenty rocker switches with corresponding light emitting diodes (LEDs). When all LEDs are illuminated, the car will operate normally. The fault panel has an access point for each switch in the panel. A fault is set when the switch is activated. This will open the electric circuit and the LED will go out. A lab scope may be used to test the failed circuit.

An advantage of having an access point goes beyond just having a place to test. Diagnostic procedures and more faults may be added at the test points. The fault box is an effective teaching tool. An instructor may design an electrical circuit and wire it into a particular circuit to trigger various alternative fault scenarios.
