How to Perform Trouble Diagnosis for Quick
and Accurate Repair
NLBR0172
INTRODUCTION
NLBR0172S01
I
Most important point to perform diagnosis is to understand
systems (control and mechanism) in vehicle thoroughly.
EFJ0028D
I
It is also important to clarify customer complaints before
inspection.
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 customer
means...” or “maybe customer mentioned this symptom”.
SEF233G
I
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 con-
nector by hand. When repairs are performed without any
symptom check, no one can judge if malfunction has actually
been eliminated.
I
After diagnosis, make sure to perform “erase memory”. Refer
to GI-35.
I
For an intermittent malfunction, move harness or harness con-
nector by hand to check poor contact or improper open circuit.
I
Always read “GI General Information” to confirm general pre-
cautions. Refer to GI-3.

ASKING COMPLAINTS
NLBR0172S03
I
Complaints against malfunction vary depending on each per-
son. It is important to clarify customer complaints.
I
Ask customer about what symptoms are present and under
what conditions. Use information to reproduce symptom while
driving.
I
It is also important to use the diagnosis sheet so as not to miss
information.
