DTC Troubleshooting: P0706 (6-2)

DTC P0706:

Open in Transmission Range Switch Circuit

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 in CLEAR MENU with the Honda PGM Tester or HDS.

2.	Move the shift lever to each position, and check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706. Did the result fail? YES - Go to 3. NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 1 and recheck.n

Inspect the transmission range switch.

Is the switch OK?

YES - Inspect the end of the selector control shaft, and go to 4.

NO - Replace the transmission range switch. Recheck for a pass/fail test of code P0706 by performing step 1 and 2 after replacing the switch. If the test result is failed, check the transmission range switch.n

4.	Install the transmission range switch correctly, and adjust the shift cable.

5.	Clear the DTC in CLEAR MENU.

6.	Move the shift lever to each position, and check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706. Did the result fail? YES - Go to 7. NO - The problem has been corrected. If the tester indicates NOT COMPLETE, return to step 5 and recheck.n

7.	Shift the shift lever into the [D] position, and verify the ATP FWD and ATP D inputs with the PGM Tester or HDS in the A/T data list. Is ATP FWD and ATP D ON? YES - Go to 8. NO - Go to 13.

8.	Shift to the [D3] position, and verify the ATP FWD and ATP D3 inputs with the PGM Tester or HDS in the A/T data list. Is ATP FWD and ATP D3 ON? YES - Go to 9. NO - Go to 13.

9.	Clear the DTC in CLEAR MENU, 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.

11.	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.

12.	Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706. Did the result fail? YES - Go to 13. NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 13 and recheck.n

13.	Turn the ignition switch OFF.

14.	Check for continuity between PCM connector terminals A8 and body ground, and between A9 and body ground. Is there continuity? YES - Go to 15. NO - Repair open in the wire between PCM connector terminal A8 and ground (G101), and between A9 and ground (G101), and repair poor ground (G101).n

15.	Turn the ignition switch ON (II).

16.	Shift the shift lever into the [D] or [D3] position.

17.

Measure the voltage between PCM connector terminals C18 and A8 or A9.

Is there voltage?

YES - Repair open in the wire between PCM connector terminal C18, C17 or C9 and the transmission range switch or between the transmission range switch connector terminal No. 10 and ground (G101).n

NO - 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
