NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, 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 R, 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 for proper transmission range switch installation, Service and Repair adjust the shift cable, Adjustments then recheck.

Is the Reverse Switch (ATPRVS) 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. 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. 6 and body ground (G101), or repair poor body ground (G101), then go to step 10.






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 battery 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 the No. 2 and No. 6 terminals at the transmission range switch, when the shift lever is in P, R, and N, and no continuity when the shift lever is in D and S.

Is there continuity when the shift lever is in P, R, and N, and no continuity when the shift lever is in D and S?
YES - Go to step 16.

NO - Replace the transmission range switch, Service and Repair then go to step 13.






10. Reconnect all connectors.

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

12. Clear the DTC with the HDS.

13. Start the engine in P. With the brake pedal pressed, shift to N from P, then shift to R, and wait for at least 2 seconds.

14. Check for Pending or Confirmed 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 HDS indicate PASSED?
YES - Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 14, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the transmission range switch and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 13.


16. Reconnect all connectors.

17. Update the PCM if it does not have the latest software, ECM/PCM Update or substitute a known-good PCM. Reading and Clearing Diagnostic Trouble Codes

18. Start the engine in P. With the brake pedal pressed, shift to N from P, then shift to R, and wait for at least 2 seconds.

19. Check for Pending or Confirmed 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, Reading and Clearing Diagnostic Trouble Codes then go to step 18. If the PCM was substituted, go to step 1.

NO - Go to step 20.


20. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.

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 Pending or Confirmed DTCs were indicated in step 19, go to the indicated DTC's troubleshooting.

NO - If the HDS 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, Reading and Clearing Diagnostic Trouble Codes then go to step 18. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 18.
