DTC DETECTION LOGIC
NOTE:
DC stands for “DRIVING CYCLE” and indicates a series of driving cycle of “Ignition switch OFF
→
ON
→
driv-
ing
→
OFF”.
DTC CONFIRMATION PROCEDURE
CAUTION:
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
With CONSULT
1.
Start the engine.
2.
Select “Data Monitor” in “TRANSMISSION”.
3.
Select “G SPEED”.
4.
Drive the vehicle.
5.
Maintain the following conditions for 5 seconds or more.
6.
Stop the vehicle.
CAUTION:
Never stop the engine.
7.
Repeat step 4 through 6.
