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. Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
3. Start the engine and turn the VSA off (the light on the VSA OFF switch comes on). Run the engine 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 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
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 COMPLETED, return to step 3 and recheck.
5. Inspect the transmission range switch.
Is the switch OK?
YES - Go to step 6.
NO - Replace the transmission range switch, then go to step 21.
6. Install the transmission range switch correctly, adjust the shift cable.
7. Clear the DTC with the HDS.
8. 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 9.
NO - Go to step 14.
9. 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 D3 ON?
YES - Go to step 10.
NO - Go to step 14.
10. Clear the DTC with the HDS, and turn the ignition switch OFF.
11. Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
12. Start the engine and turn the VSA off (the light on the VSA OFF switch comes on). Run the engine in the D position until the vehicle speed reaches 35 mph (56 km/h) then slow down and stop the wheels.
13. Monitor the OBD status for P0706 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 14.
NO - intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmission range switch and the PCM. If the tester indicates NOT COMPLETED, return to step 12 and recheck.
14. Turn the ignition switch OFF.
15. Disconnect the transmission range switch connector.
16. Check for continuity between transmission range switch connector terminal No. 5 and body ground.
Is there continuity?
YES - Go to step 17.
NO - Repair an open in the wire between the transmission range switch and ground (G101, G102), or repair a poor ground (G101, G102), then go to step 21.
17. Turn the ignition switch ON (II).
18. Measure the voltage between transmission range switch connector terminals No. 5 and No. 6.
Is there voltage?
YES - Go to step 19.
NO - Repair an open in the wire between the transmission range switch and PCM connector terminal C19, then go to step 21.
19. Measure the voltage between transmission range switch connector terminals No. 2 and No. 5.
Is there voltage?
YES - Go to step 20.
NO - Repair an open in the wire between the transmission range switch and PCM connector terminal C10, then go to step 21.
20. Measure the voltage between transmission range switch connector terminals No. 5 and No. 7.
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.
NO - Repair an open in the wire between the transmission range switch and PCM connector terminal C18, then go to step 21.
21. Clear the DTC with the HDS.
22. Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.
23. Start the engine and turn the VSA off (the light on the VSA OFF switch comes on). Run the engine in the D position until the vehicle speed reaches 35 mph (56 km/h), then slow down and stop the wheels.
24. Monitor the OBD status for P0706 in the 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 5 and recheck.
