How to Perform Trouble DiagnosesNES000JU
BASIC CONCEPT
The most important point to perform trouble diagnosis is to understand systems (control and mechanism)
in vehicle thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
they will be necessary to check symptom by driving vehicle with
customer.
CAUTION:
Customers are not professionals. Do not assume “maybe
customer means...” or “maybe the customer mentioned this
symptom”.
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples.
Do not perform inspection on ad hoc basis. Most intermittent
malfunctions are caused by poor contacts. In this case, it will be
effective to shake suspected harness or connector by hand.
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.
Always diagnosis, make sure to perform “ERASE MEMORY”.
Always read “GI General information” to confirm general precau-
tions. Refer to GI-4, "
General Precautions" .
