How to Perform Trouble Diagnosis For Quick and Accurate RepairBFS000CU
INTRODUCTION

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 symptoms, and understand them fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check symptoms by driving vehicle
with the customer.
NOTE:
Customers are not professionals. Do not assume “maybe the
customer means...” or “maybe the customer mentioned this
symptoms”.

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
symptoms based on an interview with customers 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 connec-
tors by hand. When repairs are performed without any symptom
check, no one can judge if malfunction has actually been elimi-
nated.

After diagnosis, make sure to perform “erase memory”. Refer to
BRC-17, "
ERASE MEMORY" .

For an intermittent malfunction, move harness or harness connectors by hand to check poor contacts or
false open circuit.

Always read “GI section” to confirm general precautions. Refer to GI-4, "General Precautions" .

ASKING COMPLAINTS

Complaints vary depending on the person. It is important to clar-
ify the customer's actual remarks.

Ask the customer about what symptoms are present and under
what conditions. Use the information to reproduce the symptom
while driving.

It is also important to use diagnosis sheet so as not to miss vital
information.
