DTC Troubleshooting: P0706 (6-2)

DTC P0706:  Open in Transmission Range Switch Circuit

NOTE:

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, drive the vehicle in the D position until the vehicle speed reaches 56 km/h (35 mph), 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 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 1 and recheck.n


5.Test the transmission range switch.

Is the switch OK?


YES - Go to 6.


NO - Replace the transmission range switch, then go to 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, drive the vehicle in the D position until the vehicle speed reaches 56 km/h (35 mph), then slow down and stop the wheels.

10.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 11.


NO - The problem has been corrected. If the tester indicates NOT COMPLETE, return to 7 and recheck.n


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 12.


NO - Go to 18.


12.Shift to the 2 position, and verify the ATP FWD and ATP 2 inputs with the HDS in the A/T date list.

Is the ATP FWD and ATP 2 ON?


YES - Go to 13.


NO - Go to 18.


13.Shift to the 1 position, and verify the ATP FWD and ATP 1 signals with the HDS in the A/T data list.

Is the ATP FWD and ATP 1 ON?


YES - Go to 14.


NO - Go to 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, drive the vehicle in the D position until the vehicle speed reaches 56 km/h (35 mph), then slow down and stop the wheels.

17.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 18.


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 14 and recheck.n

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 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 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 voltage?


YES - Go to 23.


NO - Repair open in the wire between the transmission range switch and PCM connector terminal C18, then go to 26.


23.Measure the voltage between transmission range switch connector terminals No. 8 and No. 10.

 

Is there voltage?


YES - Go to 24.


NO - Repair open in the wire between the transmission range switch and PCM connector terminal C17, then go to 26.

24.Measure the voltage between transmission range switch connector terminals No. 3 and No. 10.

 

Is there voltage?


YES - Go to 25.


NO - Repair open in the wire between the transmission range switch and PCM connector terminal C11, then go to 26.

25.Measure the voltage between transmission range switch connector terminals No. 9 and No. 10.

 

Is there 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.n


NO - Repair open in the wire between the transmission range switch and PCM connector terminal C9, then go to 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, drive the vehicle in the D position until the vehicle speed reaches 56 km/h (35 mph), then slow down and stop the wheels.

30.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 pass?


YES - The problem has been corrected.n


NO - Return to 1 and recheck.n
