DTC P1717: Open in Transmission Range Switch ATPRVS Switch Circuit
- Before you troubleshoot, record all freeze data and any on-board snapshot, 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.
- Some wire colors vary according to the model year, and are indicated with an asterisk as follows:
- *1: '09-11 models
- *2: '12 model
- Turn the ignition switch to ON (II).
- 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.
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 terminals No. 2 and No. 6.

Is there battery voltage?
YES -Go to step 8.
NO -Repair open in the wire between PCM connector terminal C19 and the transmission range switch, then go to step 14.
- 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, 2, and 1.

Is there continuity when the shift lever is in P, R, and N, and no continuity when the shift lever is in D, 2 and 1?
YES -Go to step 9.
NO -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ), then go to step 14.
- Connect the transmission range switch connector.
- Update the A/T software in the PCM if it does not have the latest software (see PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE 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 -If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, 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 -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see PCM REPLACEMENT ). If any other Pending or Confirmed DTCs were indicated on step 12, go to the indicated DTC's troubleshooting.
NO -If the HDS indicates FAILED, check for poor connections and loose terminals between the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 11.
- Connect the transmission range switch connector.
- 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 and loose terminals between the transmission range switch and the PCM, then 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 -Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated on step 17, go to the indicated DTC's troubleshooting.
NO -If the HDS indicates FAILED, check for poor connections and loose terminals between the transmission range switch and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 16.
