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), or press the engine start/stop button to select the ON mode
- 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 REPLACEMENT ), adjust the shift cable (see SHIFT CABLE ADJUSTMENT ), then recheck
- Check the Reverse Switch (ATPRVS) signal with the HDS
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Disconnect the transmission range switch connector.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Connect a jumper wire between transmission range switch connector terminals No. 2 and body ground.

Is the Reverse Switch (ATPRVS) ON in the HDS A/T Data List?
YES -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ), then go to step 8.
NO -Repair an open in the wire between PCM connector terminal C19 and the transmission range switch, then go to step 14.
- Reconnect all connectors.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
- Clear the DTC with the HDS
- Start the engine in P With the brake pedal pressed, shift to R, and wait for at least 2 seconds in R, then shift to N
- 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 13
- 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 12, 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 11.
- 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 in P With the brake pedal pressed, shift to R, and wait for at least 2 seconds in R, then shift to N
- 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 (see SUBSTITUTING THE ECM/PCM ), then go to step 16. If the PCM was substituted, go to step 1.
NO -Go to step 18
- 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 Pending or Confirmed DTCs were indicated in step 17, 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 16. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 16.
Is the Reverse Switch (ATPRVS) ON?
YES -Intermittent failure, the system is OK at this time
NO -Go to step 4
