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 to ON (II).
2. Shift to P, R, and N, and check the A/T R SWITCH in the DATA LIST with the HDS.
Is the A/T R SWITCH ON?
YES - Go to step 3.
NO - Check the transmission range switch installation, and adjust the shift cable, then recheck.
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 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 the transmission range switch and ground (G101), or repair poor ground (G101), then go to step 11.
7. Turn the ignition switch to ON (II).
8. Measure the voltage between transmission range switch connector terminals No. 5 and No. 9.
Is there voltage?
YES - Go to step 9.
NO - 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 P, R, and N, and when the shift lever is shifted to any position other than P, R, and N.
Is there continuity while the shift lever is in P, R, and N, and no continuity when the shift lever is shifted to any position other than the P, R, and N?
YES - Go to step 15.
NO - Replace the transmission range switch, then go to step 11.
10. Measure the voltage between PCM connector terminal C21 and body ground.
Is there battery voltage?
YES - Repair open in the wire between the transmission range switch and PCM connector terminal C21, then go to step 11.
NO - Go to step 15.
11. Clear the DTC with the HDS.
12. Start the engine with the brake pedal pressed, and shift the shift lever slowly into P, R then N. Shifting R, wait for at least 2 seconds.
13. 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 14.
14. 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 13, 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 12.
15. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
16. Start the engine with the brake pedal pressed, then move the shift lever slowly from P into R, then N, stopping at least 2 seconds in each position.
17. 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 16. If the PCM was substituted, go to step 1.
NO - Go to step 18.
18. 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 17, 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 16. If the screen indicates NOT COMPLETED, go to step 16.
