DTC CONFIRMATION PROCEDURE
CAUTION:
• Be sure to perform “
” and then perform “DTC CONFIRMATION PRO-
CEDURE”.
• Never perform “DTC CONFIRMATION PROCEDURE” before the repairs. Doing so may result in a sec-
ondary malfunction.
• Be careful of the driving speed.
1.
PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.
CHECK DTC DETECTION
1. Start the engine.
2. Drive the vehicle.
3. Maintain the following conditions for 20 seconds or more.
4. Stop the vehicle.
5. Check the first trip DTC.

NO
>> Repair or replace malfunctioning parts.
2.
CHECK PRIMARY PRESSURE SOLENOID VALVE
Check primary pressure solenoid valve. Refer to
TM-206, "Component Inspection"
Is the inspection result normal?
YES >> Check
intermittent incident. Refer to
GI-39, "Intermittent Incident"
.
NO
>> Repair or replace malfunctioning parts.
