DTC P1717: Open in Transmission Range Switch ATP RVS Switch CircuitNOTE:
^ Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
^ 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 ON (II).
2. Shift to the R position, and verify the A/T R SWITCH signal in the DATA LIST with the HDS.
Is the A/T R SWITCH ON?
YES - Go to step 3.
NO - Check for proper transmission range switch installation, adjust the shift cable.
3. Check the REVERSE SWITCH 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 OFF.
5. Disconnect the transmission range switch connector.
6. Check 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), or repair poor ground (G101), then go to step 10.
7. Turn the ignition switch ON (II).
8. Measure voltage between transmission range switch connector terminals No. 5 and No. 9.
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 10.
9. Check for continuity between transmission range switch connector terminals No. 5 and No. 9 while the shift lever is in the R position, and when the shift lever is shifted to any position other than R.
Is there continuity while the shift lever is in the R position, and no continuity when the shift lever is shifted to any position other than R?
YES - Go to step 16.
NO - Replace the transmission range switch, then go to step 10.
10. Reconnect all connectors.
11. Turn the ignition switch ON (II).
12. Clear the DTC with the HDS.
13. Start the engine, and shift the shift lever slowly into the P, R then N position.
14. Check for DTCs with the HDS.
Is DTC P1717 indicated?
YES - Check for poor connections or loose terminals between the transmission range switch and the PCM, then go to step 1.
NO - Go to step 15.
15. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated in step 14, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals between the transmission range switch and the PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 13.
16. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
17. Start the engine, and shift the shift lever slowly into the P, R then N position.
18. Check for DTCs with the HDS.
Is DTC P1717 indicated?
YES - Check for poor connections or loose terminals between the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 17. If the PCM was substituted, go to step 1.
NO - Go to step 19.
19. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other DTCs were indicated in step 18, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals between the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 17. If the screen indicates NOT COMPLETED, go to step 17.
