Acura RL. Manual - part 235

4. Restart the engine, and run it in D until the vehicle speed reaches 25 mph (40 km/h), then slow down and 

stop the wheels.  

5. Monitor the OBD STATUS for P0706 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. 

Does the HDS indicate FAILED?  

YES - Go to step 6. 

NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at 
the transmission range switch and the PCM. If the HDS indicates NOT COMPLETED, return to step 3 
and recheck. 

6. Inspect the transmission range switch (see TRANSMISSION RANGE SWITCH TEST ). 

Is the switch OK?  

YES - Go to step 7. 

NO - Replace the transmission range switch (see TRANSMISSION RANGE SWITCH 
REPLACEMENT ), then go to step 28. 

7. Install the transmission range switch correctly, and adjust the shift cable (see SHIFT CABLE 

ADJUSTMENT ).  

8. Clear the DTC with the HDS.  

9. Shift to the D, and verify the ATP FWD and ATP D inputs with the HDS in the A/T data list. 

Are ATP FWD and ATP D ON?  

YES - Go to step 10. 

NO - Go to step 15. 

10. Shift to the D3, and verify the ATF FWD and ATP D3 inputs with the HDS in the A/T data list. 

Are ATP FWD and ATP D3 ON?  

YES - Go to step 11. 

NO - Go to step 15. 

11. Clear the DTC with the HDS, and turn the ignition switch to LOCK (0).  

12. Run the engine in D until the vehicle speed reaches 25 mph (40 km/h), then slow down, stop the wheels, 

and turn the ignition switch to LOCK (0).  

13. Restart the engine, and run it in D until the vehicle speed reaches 25 mph (40 km/h), then slow down and 

stop the wheels.

14. Monitor the OBD STATUS for P0706 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. 

Does the HDS indicate FAILED?  

YES - Go to step 15. 

NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at 
the transmission range switch and the PCM. If the HDS indicates NOT COMPLETED, return to step 12 
and recheck. 

15. Turn the ignition switch to LOCK (0).  

16. Disconnect the transmission range switch connector.  

17. Check for continuity between transmission range switch connector terminal No. 5 and body ground.

Is there continuity?  

YES - Go to step 18. 

NO - Repair open in the wire between the transmission range switch and ground (G101, G102), or repair 
poor ground (G101, G102), then go to step 28. 

18. Turn the ignition switch to ON (II).  

19. Measure the voltage between transmission range switch connector terminals No. 5 and No. 6.

Is there voltage?  

YES - Go to step 21. 

NO - Repair open in the wire between the transmission range switch and PCM connector terminal C10, 
then go to step 28. 

21. Measure the voltage between transmission range switch connector terminals No. 5 and No. 7.

Is there voltage?  

YES - Go to step 22. 

NO - Repair open in the wire between the transmission range switch and PCM connector terminal C18, 
then go to step 28. 

22. Connect the transmission range switch connector.  

23. Update the A/T software in the PCM if it does not have the latest software (see UPDATING THE 

PCM ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).  

24. Run the engine in D until the vehicle speed reaches 30 mph (48 km/h), then slow down, stop the wheels, 

and turn the ignition switch to LOCK (0).  

25. Restart the engine, and run it in D until the vehicle speed reaches 30 mph (48 km/h), then slow down and 

stop the wheels.  

26. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS. 

Is DTC P0706 indicated?  

YES - If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), 
then recheck. If the PCM was substituted, go to step 1. 

NO - Go to step 27. 

27. Monitor the OBD STATUS for P0706 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. 

Does the HDS indicate PASSED?  

YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the 
original PCM (see PCM REPLACEMENT ). If any other DTCs were indicated on step 26, go to the 
INDICATED DTCS TROUBLESHOOTING.
