DTC Troubleshooting: P1717 (62-1)
|DTC P1717:||Open in Transmission Range Switch ATP RVS Switch Circuit|
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review 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 ON (II).|
|2.||Shift to the R position, 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 3.
NO - Check for proper transmission range switch installation, adjust the shift cable, then recheck.n
|3.||Check the REVERSE SWITCH signal with the HDS.|
Is the REVERSE SWITCH ON?
YES - Intermittent failure, the system is OK at this time.n
NO - Go to 4.
|4.||Turn the ignition switch OFF.|
|5.||Disconnect the transmission range switch connector.|
|6.||Check for continuity between transmission range switch connector terminal No. 10 and body ground.|
Is there continuity?
YES - Go to 7.
NO - Repair open in the wire between transmission range switch connector terminal No. 10 and ground (G101), or repair poor ground (G101), then go to 10.
|7.||Turn the ignition switch ON (II).|
|8.||Measure voltage between transmission range switch connector terminals No. 1 and No. 10.|
Is there voltage?
YES - Go to 9.
NO - Repair open in the wire between PCM connector terminal B22 and the transmission range switch, then go to 10.
|9.||Check for continuity between transmission range switch connector terminals No. 1 and No. 10 while the shift lever is in the R position, and when the shift lever is shifted to any position other than R.|
Is there continuity while the shift lever is in the R position, and no continuity when the shift lever is shifted to any position other than R?
YES - Check for loose or poor connections at PCM connector terminal B22. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n
|10.||Clear the DTC with the HDS.|
|11.||Test-drive the vehicle in the R position at speeds below 5 km/h (3 mph) for more than 2 seconds, then increase the speed and test-drive at speeds over 5 km/h (3 mph) for more than 2 seconds. Slow down and stop the wheels.|
|12.||Monitor the OBD status for P1717 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.|
Does the result indicate PASSED?
YES - Troubleshooting is complete.n
NO - Return to 4 and recheck.
