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 8 seconds or more.

6. Stop the vehicle.

CAUTION:

Never stop the engine.

7. Repeat steps 4 through 6.

8. Check the DTC.
Is “P1588” detected?

YES

>> Go to 

TM-221, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009759471
