Step 2. DTC / Freeze Frame Data Check, Record and
Clearance

DTC. If DTC exists, print or write down DTC and freeze
frame data and then clear malfunction DTC(s) by
referring to "DTC Clearance". 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.

"applicable DTC flow", locate the cause of the trouble,
namely in a sensor, switch, wire harness, connector,
actuator, TCM or other part and repair or replace faulty
parts.
