Points to note when diagnosing faults
It is not possible to give any general rules on how fault diagnosis should be carried out
in each individual case. Depending on the fault symptoms and other available information, one
method could be best in a certain situation only to be less suitable in another. However, the
following points may serve as guidelines in connection with fault diagnosis in the MOTRONIC
system and it may not be a bad idea to recall the information on this page from time to time
when diagnosing faults.
