DTC P1717: Open in Transmission Range Switch ATPRVS Switch Circuit
- 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.
- Turn the ignition switch to ON (II).
- Shift to R, 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 for proper transmission range switch installation (see TRANSMISSION RANGE SWITCH REPLACEMENT ), adjust the shift cable (see SHIFT CABLE ADJUSTMENT ), then recheck.
- Check the Reverse Switch (ATPRVS) in the Data List with the HDS.
Is the Reverse Switch (ATPRVS) ON?
YES -Intermittent failure, the system is OK at this time.
NO -Go to step 4.
- Turn the ignition switch to LOCK (0).
- Disconnect the transmission range switch connector.
- Turn the ignition switch to ON (II).
- Measure the voltage between transmission range switch connector terminal No. 1 and body ground.

Is there battery voltage?
YES -Go to step 8.
NO -Repair open in the wire between PCM connector terminal C12 and the transmission range switch, then go to step 9.
- Shift to R and check for continuity between the No. 1 and No. 10 terminals at the transmission range switch.

Is there continuity when 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 15.
NO -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ), then go to step 10.
- Reconnect all connectors.
- Turn the ignition switch to ON (II).
- Clear the DTC with the HDS.
- Start the engine with the shift lever in P. Shift to N from P, then shift to R, and wait for at least 2 seconds.
- Check for Temporary DTCs or 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.
- 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 Temporary DTCs or 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 12.
- Reconnect all connectors.
- Update 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 ).
- Start the engine with the shift lever in P. Shift to N from P, then shift to R, and wait for at least 2 seconds.
- Check for Temporary DTCs or 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 (see SUBSTITUTING THE ECM/PCM ), then go to step 17. If the PCM was substituted, go to step 1.
NO -Go to step 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 (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or 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 (see SUBSTITUTING THE ECM/PCM ), then go to step 17. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 17.
