Information Gathering
To properly diagnose a malfunction, one must not make guesses or assumptions about the circumstances that caused
it. Proper diagnosis and repair require duplicating the situation in which the malfunction occurred. If a diagnosis is
made without duplicating the malfunction, even an experienced service technician may make a misdiagnosis and not
perform the servicing procedure correctly, resulting in the malfunction not being repaired. For example, a malfunction
that occurs only while braking on slippery surfaces will not occur if the motorcycle is ridden on a non-slippery surface.
Therefore, in order to properly diagnose and repair the motorcycle, the customer must be questioned about the
conditions at the time that the malfunction occurred making "Information gathering" very important. In order that the
information obtained from the customer to be used as a reference during troubleshooting, it is necessary to ask certain
important questions concerning the malfunction. Therefore, a questionnaire has been created to improve the
information-gathering procedure.
