How to Proceed with DiagnosisAFS001SL
BASIC CONCEPT
Most important point to perform 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,
it will be necessary to check symptom by driving vehicle with
customer.
NOTE:
Customers are not professionals. Do not assume “maybe cus-
tomer means...” or “maybe 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.
After diagnosis, make sure to perform “erase memory”. Refer to
BRC-27, "
SELF-DIAGNOSIS" .
For an intermittent malfunction, move harness or harness con-
nector by hand to check poor contact or false open circuit.
Always read “GI General Information” to confirm general precautions. Refer to GI-4, "General Precau-
tions" .

ASKING COMPLAINTS
Complaints against malfunction vary depending on each person.
It is important to clarify customer complaints.
Ask customer about what symptoms are present and under
what conditions. Use information to reproduce symptom while
driving.
It is also important to use diagnosis sheet so as not to miss infor-
mation.
