case a 1st trip DTC other than P0731 is shown, refer to “AT- 8 6 , "
Display Items List" ”.
If “COMPLETED RESULT NG” is detected, go to AT- 11 6 , "
Diagnostic Procedure" .
If “STOP VEHICLE” is detected, go to the following step.
6. Stop vehicle.
7. Drive vehicle in “D” position allowing it to shift from 1st to 5th gear and check shift timing and shift shock.
–Touch “OK” to complete the inspection when normally shifted from the 1st to 5th gear.
