Determination of Probable Causes
4Repair and ConfirmationObserve the symptom carefully. Check if there are also
other problems.
In determining the probable causes, it is necessary to
study the wiring diagram to understand the circuit as a
system. Knowledge of switches, relays and other parts is
necessary for accurate analysis. The causes of similar
problems in the past must be taken into account.
Troubleshooting is carried out by making step-by-step
checks until the cause is found.
After the problems are corrected, be sure to check that the
system operates correctly. Also check that new problems
have not been caused by the repair.
