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 and wait for 5 seconds or more.
2. Check the first trip DTC.
Is
“P0778” detected?
YES >> Go to TM-332, "Diagnosis Procedure".
NO >> INSPECTION END
