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.

The following page view includes every component that should be checked

before the engine start. For example, calibrations can be checked if they were

successful.

To check every component, the following page view also allows every component

to be checked that requires the engine to be running.

Another option that provides an excellent monitoring function during the engine

start procedure is the information page on the display, which is usually selected

when warming up the car.

Important: Not all errors are displayed on the error page in the dashboard, but

in fact only those required for ideal operation of the car.

Monitoring values via the display during the engine start procedure is

complemented by another page view in RaceCon. The engine’s actual status is

indicated in the left field of the page. In contrast to the previous page views, the

pressures and temperatures are listed separately, which provides improved

performance when monitoring the most important values.

In addition, the combustion process in the cylinders can be checked in the

lambda and camshaft sensor fields.

The possibility to monitor the car during the engine start procedure internally

via the display as well as externally via the page views significantly reduces the

possibility of overlooking deviating values.
