DTC P0706: Open in Transmission Range Switch CircuitNOTE:
^ Record all freeze data and review the 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 vehicle, make sure it is securely supported, and allow. the all four wheels to rotate freely.
3. Start the engine, drive the vehicle in the D position until the vehicle speed reaches 31 mph (50 km/h), then slow down and stop the wheels.
4. Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0706.
Did the result indicate a fail?
YES-Go to step 5.

Did the result indicate a fail?
YES-Go to step 11.
NO-The problem has been corrected. If the tester indicates NOT COMPLETE, 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 ATP FWD and ATP D ON?
YES-Go to step 12.
NO-Go to step 19.
12. Shift to the D3 position, and verify the ATP FWD and ATP D3 inputs with the HDS in the A/T data list.
Is ATP FWD and ATP D 0N?
YES-Go to step 13.
NO-Go to step 19.
13. Shift to the 2 position, and verify the ATP FWD and ATP 2 inputs with the HDS in the A/T data list.
Is ATP FWD and ATP 2 ON?
YES-Go to step 14.
NO-Go to step 19.
14. Shift to the 1 position, and verify the ATP I input with the HDS in the A/T data list.
Is ATP 1 ON?
YES-Go to step 15.
NO-Go to step 19.
15. Clear the DTC with the HDS, and turn the ignition switch OFF.
16. Raise the vehicle, make sure it is securely supported, and allow the all four wheels to rotate freely,
17. 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.
18. Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0706.
Did the result indicate a fail?
YES-Go to step 19.
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 15 and recheck.
19. Turn the ignition switch OFF.
20. Disconnect the transmission range switch connector.
21. Check for continuity between transmission range switch connector terminal No. 6 and body ground.
Wire side of female terminals
Is there continuity?
YES-Go to step 22.
NO-Repair open in the wire between the transmission range switch and ground (G101), or repair poor ground (G101), then go to step 31.
22. Turn the ignition switch ON (II).
23. Measure the voltage between transmission range switch connector terminals No. 10 and No. 6.
Wire side of female terminals
Is there voltage?
YES-Go to step 24.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal A12, then go to step 31.
24. Measure the voltage between transmission range switch connector terminals No. 4 and No. 6.
Wire side of female terminals
Is there voltage?
YES-Go to step 25.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C30, then go to step 31.
25. Measure the voltage between transmission range switch connector terminals No. 9 and No. 6.
Wire side of female terminals
Is there voltage?
YES-Go to step 26.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C31, then go to step 31.
26. Measure the voltage between transmission range switch connector terminals No. 3 and No. 6.
Is there voltage?
YES-Go to step 27.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C32, then go to step 31.
27. Measure the voltage between transmission range switch connector terminals No. 8 and No. 6.
Is there voltage?
YES-Go to step 28.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C33, then go to step 31.
28. Measure the voltage between transmission range switch connector terminals No. 2 and No. 6.
Is there voltage?
YES-Go to step 29.
NO-Repair open in the wire between the transmission range, switch and PCM connector terminal C34, then go to step 31.
29. Measure the voltage between transmission range switch connector terminals No. 7 and No. 6.
Is there voltage?
YES-Go to step 30.
NO-Repair open in the wire between the transmission range switch and PCM connector terminal C35, then go to step 31.
30. Measure the voltage between transmission range switch connector terminals No. 1 and No. 6.
