DTC P0706: Transmission Range Switch Circuit (Open)

NOTE:
^ Record all freeze data and review General Troubleshooting Information before you troubleshoot.
^ This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Clear the DTC with the HDS.
2. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely.
3. Start the engine, drive the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
4. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706.
Did the result indicate a fail?
YES-Go to step 5.
NO-Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmission range switch and PCM. If the tester indicates NOT COMPLETE, return to step 1 and recheck.
5. Inspect the transmission range switch.
Is the switch OK ?
YES-Inspect the end of the selector control shaft, then go to step 6.
NO-Replace the transmission range switch, then go to step 17.
6. Install the transmission range switch correctly, and adjust the shift cable.
7. Clear the DTC with the HDS.
8. Shift the shift lever into the D position, and verify the ATP D inputs with the HDS in the A/T data list.
Is the ATP D ON?
YES-Go to step 9.
NO-Go to step 13.
9. Clear the DTC with the HDS, and turn the ignition switch OFF.
10. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely.

13. Turn the ignition switch OFF.
14. Disconnect the transmission range switch connector.





15. Check for continuity between transmission range switch connector terminal No. 6 and body ground.
Is there continuity?
YES-Go to step 16.
NO-Repair open in the wire between transmission range switch connector terminal No. 6 and ground (G101, G102), or repair poor ground (G101, G102), then go to step 17.





16. Measure the voltage between transmission range switch connector terminals No. 3 and No. 6.
Is there battery voltage?
YES-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.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C10, then go to step 17.
17. Clear the DTC with the HDS.
18. Turn the ignition switch OFF.
19. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely.
20. Start the engine, drive the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
21. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706.
Did the result indicate a pass?
