The thresholds of some engine parameter functions are displayed, considered fundamental to identify the type of
engine use: The thresholds of some engine parameter functions are displayed, considered fundamental to identify
the type of engine use:
The set threshold value of some parameters is displayed, the “Minimum interval” delay and the number of times “Number of warnings” is exceeded.
Use the cursor to select the condition you would like to see in detail (for example, the “RPM High” engine status), press <Enter> to access the following window. For every occasion the threshold was exceeded (up to a maximum of 16including the last two occasions in the order “Last and Penultimate”), this window displays the following information:
the “Max … or Min …” maximum peak achieved, the initial moment of the exceeded threshold as regards the “Time”
control unit, the “RPM” engine status at the start of the reading, the absolute pressure in the “MAP” intake manifold,
the temperature of the “TH20” engine coolant when the threshold was exceeded and the “Duration”.
