P0706
DTC P0706: Open in Transmission Range Switch CircuitNOTE:
^ 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. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
3. Start the engine, run the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
4. Monitor the OBD status for P0706 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 5.
NO - If the tester indicates PASSED, 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 COMPLETED, return to step 1 and recheck.
5. Test the transmission range switch.
Is the switch OK?
YES - Inspect the end of the selector control shaft, and go to step 6.
NO - Replace the transmission range switch, then go to step 24.
6. Install the transmission range switch correctly, and adjust the shift cable.
7. Clear the DTC with the HDS.
8. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
9. Start the engine, run the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
10. Monitor the OBD status for P0706 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 11.
NO - If the tester indicates PASSED, troubleshooting is complete. If the tester indicates NOT COMPLETED, return to step 7 and recheck.
11. Shift the shift lever into the D position, and verify the ATP FWD and ATP D inputs with the HDS in the A/T data list.
Is the ATP FWD and ATP D ON?
YES - Go to step 12.
NO - Go to step 18.
12. Shift to the 2 position, and verify the ATP FWD and ATP 2 inputs with the HDS in the A/T data list.
Is the ATP FWD and ATP 2 ON?
YES - Go to step 13.
NO - Go to step 18.
13. Shift to the 1 position, and verify the ATP FWD and ATP 1 inputs with the HDS in the A/T data list.
Is the ATP FWD and ATP 1 ON?
YES - Go to step 14.
NO - Go to step 18.
14. Clear the DTC with the HDS, and turn the ignition switch OFF.
15. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
16. Start the engine, run the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
17. Monitor the OBD status for P0706 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 18.
NO - If the tester indicates PASSED, 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 COMPLETED, return to step 14 and recheck.
18. Turn the ignition switch OFF.
19. Disconnect the transmission range switch connector.
20. Check for continuity between transmission range switch connector terminal No. 10 and body ground.
Is there continuity?
YES - Go to step 21.
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 step 26.
21. Turn the ignition switch ON (II).
22. Measure the voltage between transmission range switch connector terminals No. 5 and No. 10.
Is there battery voltage?
YES - Go to step 23.
NO - Repair open in the wire between the transmission range switch and PCM connector terminal C18, then go to step 26.
23. Measure the voltage between transmission range switch connector terminals No. 8 and No. 10.
Is there battery voltage?
YES - Go to step 24.
NO - Repair open in the wire between the transmission range switch and PCM connector terminal C17, then go to step 26.
24. Measure the voltage between transmission range switch connector terminals No. 3 and No. 10.
Is there battery voltage?
YES - Go to step 25.
NO - Repair open in the wire between the transmission range switch and PCM connector terminal C11, then go to step 26.
25. Measure the voltage between transmission range switch connector terminals No. 9 and No. 10.
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 C9, then go to step 26.
26. Clear the DTC with the HDS.
27. Turn the ignition switch OFF.
28. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.
29. Start the engine, run the vehicle in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
30. Monitor the OBD status for P0706 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 1 and recheck.
