slow down to a stop.  

6. Turn the ignition switch to LOCK (0). Repeat step 5, then go to step 7.  

7. Monitor the OBD STATUS for P0766 or P0767 in the DTCs/Freeze Data in A/T Mode Menu for a 

pass/fail. 

Does the HDS indicate FAILED?  

YES - Go to step 8. 

NO - Intermittent failure, the system is OK at this time. If the HDS indicates NOT COMPLETED, return 
to step 5 and recheck. 

8. Clear the DTC with the HDS.  

9. Select Shift Solenoid D in the Miscellaneous Test Menu, and check that shift solenoid valve D operates 

with the HDS.
