Step 1: Customer complaint analysis
Record details of the problem (failure, complaint) and how it occurred as described by the customer.
For this purpose, use of such a questionnaire form as shown in the following will facilitate collecting information to the
point required for proper analysis and diagnosis.
Customer questionnaire (Example)
NOTE
The form is a standard sample. It should be modified according to conditions characteristic of each
market.
Step 2. DTC / freeze frame data check, record and
clearance
First, referring to “DTC Check: Motor-Shift Type
(Transfer with Shift Actuator)”, check DTC and pending
DTC. If DTC exists, print or write down DTC and freeze
frame data and then clear malfunction DTC(s) by
referring to “DTC Clearance: Motor-Shift Type (Transfer
with Shift Actuator)”. Malfunction DTC indicates
malfunction in the system but it is not possible to know
from it whether the malfunction is occurring now or it
occurred in the past and normal condition has been restored. In order to know that, check symptom in
question according to Step 5 and then recheck DTC
according to Step 6.
Diagnosing a trouble based on the DTC in this step only
or failure to clear the DTC in this step may result in an
faulty diagnosis, trouble diagnosis of a normal circuit or
difficulty in troubleshooting which is otherwise
unnecessary.
