900 - 2 Diagnosis
The R8 LMS on-board system architecture provides complete diagnostic
capability of almost every actuator and sensor. As a result, there are several
options available to detect and diagnose errors.
One option is via the RaceCon interface when the ERROR page is selected. This
page displays every monitored variable, which is controlled or received by the
ECU. Ideally, every error entry displays FALSE, which means that there are no
errors.
Occasionally error entries can indicate TRUE, when for example the
corresponding sensor is disconnected (e.g. damper travel and exhaust
temperature).
Several errors can only be diagnosed when the engine is running.
To control single components the option exists to implement checks both before
and during the engine start. In this case, the components are organised
according to their type. In this way, all relevant signal values such as voltage,
opening angle or similar can be viewed at a glance.
