Go to step 8.
NO -
Repair an open in the wire between PCM connector terminal B23 and the transmission range switch, then go to step 9.
8. Check for continuity between transmission range switch connector terminals No. 5 and No. 6 when the shift lever is in R, and when the shift lever is shifted to any position other than R.
Is there continuity when the shift lever is in R, and no continuity when the shift lever is shifted to any other position?
YES -
Go to step 15.
NO -
Replace the transmission range switch Service and Repair, then go to step 9.

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 14.
14. 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 13, 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.
15. Reconnect all connectors.
16. Update the PCM if it does not have the latest software ECM/PCM Update (M/T), or substitute a known-good PCM.
17. Start the engine with the shift lever in P. With the brake pedal pressed, shift to N from P, then shift to R, and wait for at least 2 seconds.
18. 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, then go to step 17. If the PCM was substituted, go to step 1.
NO -
Go to step 19.
19. 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 18, 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, then go to step 17. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 17.
