Is there continuity?  

YES - Replace shift solenoid valve D (see SHIFT SOLENOID VALVE TEST AND 
REPLACEMENT ), then go to step 20. 

NO - Replace the shift solenoid harness (see SHIFT SOLENOID VALVE TEST AND 
REPLACEMENT ), then go to step 20. 

15. Connect PCM connectors A (31P), B (24P), and C (22P).  

16. 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 ).  

17. Start the engine in P. With the brake pedal pressed, shift to N, and wait for at least 1 second.  

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

Is DTC P0983 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 19. 

19. Monitor the OBD STATUS for P0983 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 18, go to the

INDICATED DTCS TROUBLESHOOTING.

NO - Check for poor connections and loose terminals at shift solenoid valve D and the PCM. 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. If the HDS indicates NOT COMPLETED, return to step 17 and 
recheck. 

20. Clear the DTC with the HDS.  

21. Start the engine in P. With the brake pedal pressed, shift to N, and wait for at least 1 second.  

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

Is DTC P0983 indicated?  

YES - Check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to 
step 1. 

NO - Go to step 23. 

23. Monitor the OBD STATUS for P0983 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. 

Does the HDS indicate PASSED?  

YES - Troubleshooting is complete. If any other DTCs were indicated on step 22, go to the INDICATED 
DTCS TROUBLESHOOTING. 

NO - Check for poor connections and loose terminals at shift solenoid valve D and the PCM, then go to 
step 1. If the HDS indicates NOT COMPLETED, return to step 

21

 and recheck. 

DTC P1717: Open in Transmission Range Switch ATP RVS Switch Circuit 

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

2. Shift to R, and check the A/T R SWITCH signal with the HDS in the A/T data list. 

Is the A/T R SWITCH ON?  

YES - Go to step 3. 

NO - Check for proper transmission range switch installation (see TRANSMISSION RANGE 
SWITCH TEST ), and adjust the shift cable (see SHIFT CABLE ADJUSTMENT ), then recheck.

NOTE:



Before you troubleshoot, record all freeze data and any on-board 
snapshot, and review General Troubleshooting Information (see GENERAL 
TROUBLESHOOTING INFORMATION ).  



This code is caused by an electrical circuit problem and cannot be caused 
by a mechanical problem in the transmission.

3. Check the REVERSE SWITCH signal with the HDS. 

Is the REVERSE SWITCH ON?  

YES - Intermittent failure, the system is OK at this time. 

NO - Go to step 4. 

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

5. Disconnect the transmission range switch connector.  

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

Is there continuity?  

YES - Go to step 7. 

NO - Repair open in the wire between transmission range switch connector terminal No. 5 and ground 
(G101, G102), or repair poor ground (G101, G102), then go to step 9. 

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

8. Measure the voltage between transmission range switch connector terminals No. 5 and No. 9.
