DTC P1717: Transmission Range Switch ATPRVS Switch (Open)

NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information (see 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 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 (see TRANSMISSION RANGE SWITCH TEST ), and adjust the shift cable (see SHIFT CABLE ADJUSTMENT ), then recheck. If there is no change, go to step  4.

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

    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. 5 and body ground.

    Is there continuity? 

    YES  -Go to step 7.

    NO  -Repair an 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. 5 and No. 6.

    Is there battery voltage? 

    YES  -Go to step 9.

    NO  -Repair an open in the wire between PCM connector terminal B23 and the transmission range switch, then go to step  15.

  9. Check for continuity between transmission range switch connector terminals No. 5 and No. 6 while the shift lever is in R, and when the shift lever is shifted to any position other than R.

    Is there continuity while the shift lever is in R, and no continuity when the shift lever is shifted to any position other than R? 

    YES  -Go to step 10.

    NO  -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ), then go to step  15.

  10. Connect the transmission range switch connector.
  11. Update the A/T software in the PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ).
  12. Start the engine, and shift to R. Move the vehicle in reverse at speeds below 3 mph (5 km/h) for at least 2 seconds, then increase the speed and move at speeds above 3 mph (5 km/h) for at least 2 seconds. Slow down and stop the wheels.
  13. Check for Pending or Confirmed DTCs with the HDS.

    Is DTC P1717 indicated? 

    YES  -If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), 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 (see ECM/PCM REPLACEMENT ). If any other DTCs were indicated on step 13, go to the indicated DTC's troubleshooting.

    NO  -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 (see SUBSTITUTING THE ECM/PCM ), then recheck. If the PCM was substituted, go to step  1. If the HDS indicates NOT COMPLETED, return to step  12 and recheck.

  15. Connect the transmission range switch connector.
  16. Clear the DTC with the HDS.
  17. Start the engine, and shift to R. Move the vehicle in reverse at speeds below 3 mph (5 km/h) for at least 2 seconds, then increase the speed and move at speeds above 3 mph (5 km/h) for at least 2 seconds. Slow down and stop the wheels.
  18. Check for Pending or Confirmed 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 19.

  19. 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 18, go to the indicated DTC's troubleshooting.

    NO  -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  17 and recheck.
