DTC P1717: Open in Transmission Range Switch ATPRVS Switch Circuit

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How to Troubleshoot A/T Systems

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

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

2. Shift to P, R, and N. Then shift to R and wait at least 2 seconds. 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, Transmission Range Switch Test adjust the shift cable, Adjustments then recheck.


3. Check the Reverse Switch (ATPRVS) signal with the HDS.

Is the Reverse Switch ON (ATPRVS)?
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. 6 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), or repair poor ground (G101), then go to step 15.






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

8. Measure the voltage between transmission range switch connector terminals No. 2 and No. 6.

Is there voltage?
YES - Go to step 9.

NO - Repair open in the wire between PCM connector terminal C19 and the transmission range switch, then go to step 15.






9. Check for continuity between the No. 2 and No. 6 terminals at the transmission range switch.

Is there continuity when the shift lever is in P, R, and N, and no continuity when the shift lever is in D and D3?
YES - Check for poor connections and loose terminals at the transmission range switch and the PCM. If the connections are OK, go to step 10.

NO - Replace the transmission range switch, Transmission Range Switch Replacement then go to step 15.






10. Reconnect the transmission range switch connector.

11. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. How to Troubleshoot A/T Systems

12. Start the engine, and shift the shift lever slowly into P and R, then into N. Then, shift back into R, and wait at least 2 seconds.

13. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P1717 indicated?
YES - If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 14.


14. Monitor the OBD STATUS for P1717 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. Service and Repair If any other DTCs were indicated on step 13, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals at the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 12 and recheck.


15. Clear the DTC with the HDS.

16. Start the engine, and shift the shift lever slowly into P and R, then into N. Then, shift back into R, and wait at least 2 seconds.

17. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P1717 indicated?
YES - Check for poor connections and loose terminals at the transmission range switch and the PCM, then go to step 1.

NO - Go to step 18.


18. Monitor the OBD STATUS for P1717 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 17, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals at the transmission range switch and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 16 and recheck.
