- 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 the shift lever into the R position, and verify 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 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 OFF.
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 an open in the wire between the transmission range switch and ground (G101, G102), or repair a poor ground (G101, G102), then go to step 9.
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 an open in the wire between the transmission range switch and PCM connector terminal C21, then go to step 10.
9. Check for continuity between the No. 5 and No. 9 terminals at the transmission range switch.
Is there continuity when the shift lever is in the P, R, and N positions, and no continuity when the shift lever is in the D and D3 positions?
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 Temporary DTCs or DTCs with the HDS.
Is DTC P1717 indicated?
YES - Check for poor connections or loose terminals at 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.
NO - Return to step 4 and recheck.
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 Temporary DTCs or DTCs with the HDS.
Is DTC P1717 indicated?
YES - Check for poor connections or loose terminals at 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 - Troubleshooting is complete.
NO - Return to step 1 and recheck.
