SHOW FAILURE DATA
(DISPLAYING DATA AT THE TIME OF DTC)
ECM stores the engine and driving conditions (in the form of data as shown in the figure) at the moment of
the detection of a malfunction in its memory. This data is called "Show failure data".
Therefore, it is possible to know engine and driving conditions (e.g., whether the engine was warm or not,
where the motorcycle was running or stopped) when a malfunction was detected by checking the show fail-
ure data. This show failure data function can record the maximum of two Diagnostic Trouble Codes in the
ECM.
Also, ECM has a function to store each show failure data for two different malfunctions in the order as the
malfunction is detected. Utilizing this function, it is possible to know the order of malfunctions that have been
detected. Its use is helpful when rechecking or diagnosing a trouble.
• Click "Show failure data" 1 to display the data. By clicking the drop down button 2, either "Failure #1" or
"Failure #2" can be selected.
