DTC CONFIRMATION PROCEDURE

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 “FLUID TEMP”.

4.

Maintain the following conditions for 10 seconds or more.

5.

Check the first trip DTC.

With GST

1.

Start the engine and wait for at least 10 seconds.

CAUTION:

When the ambient temperature is less than 

−
