How to Perform Trouble Diagnoses for Quick and Accurate Repair
EFS002WZ
INTRODUCTION
●
The most important point to perform the trouble diagnosis is to understand the systems (control and
mechanism) in the vehicle thoroughly.
●
It is also important to clarify the customer complaints before
inspection.
First of all, reproduce the symptom, and understand it fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check the symptoms by driving the
vehicle with the customer.
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like “maybe the customer means that...,” or “
maybe the customer mentions this symptom”.
●
It is essential to check symptoms right from the beginning in
order to repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce the
symptom based on an interview with the customer and past
examples. Do not perform an inspection on an ad hoc basis.
Most intermittent malfunctions are caused by poor contacts. In
this case, it will be effective to shake the suspected harness or
connector by hand. When repairs are performed without any
travel diagnosis, Repair work is not confirmed if it's done cor-
rectly.
●
After the diagnosis, make sure to carry out “erase memory”.
Refer to
BRC-63, "Functions of CONSULT-II"
.
●
For an intermittent malfunction, move the harness or harness connector by hand to check the poor con-
tact or false open circuit.
●
Always read the GI Section”
to check the general guidelines and to confirm the
general precautions.
