## DTC Troubleshooting: P0706 (6-2)

DTC P0706: | Open in Transmission Range Switch Circuit

### For KB, KE, KG, and KQ Models

NOTE:

- Record all freeze data and review General Troubleshooting Information before you troubleshoot.
- The illustration shows the example of connector terminal arrangement; connector terminal arrangement varies with the models.

1. | Check whether the DTC P0705 is indicated. Is the DTC P0705 indicated? YES - Perform the DTC P0705 troubleshooting, then go to 2 after troubleshooting. NO - Go to 8.

2. | Turn the ignition switch OFF.

3. | Reset the PCM memory by removing the No. 20 ECU fuse (15A) in the under-dash fuse/relay box for more than 10 seconds, or clear the DTC with the HDS.

4. | Start off in the D position, and drive the vehicle until vehicle speed reaches 60 km/h (37 mph), then slow down and stop.

5. | Turn the ignition switch OFF, then turn it ON (II) again.

6. | Start off in the D position, and drive the vehicle until vehicle speed reaches 60 km/h (37 mph), then slow down and stop.

7. | Keep the ignition switch in ON (II) position, and check for DTC P0706. Is the DTC P0706 indicated? YES - Go to 8. NO - Intermittent failure. The problem has been corrected.n

8. | Test the transmission range switch. Is the switch OK? YES - Go to 9. NO - Replace the transmission range switch.n

9. | Connect the transmission range switch connector.

10. | Turn the ignition switch OFF.

11. | Check for continuity between PCM connector terminals A23 and body ground, and between A24 and body ground. Is there continuity? YES - Go to 12. NO - Repair open in the wire between PCM connector terminals A23 and A24, and ground (G101), or repair poor ground (G101).n

12. | Turn the ignition switch ON (II).

13. | Shift to the D position.

14. | Measure the voltage between PCM connector terminals C20 and A23 or A24. Is there voltage? YES - Repair open in the wire between PCM connector terminal C20 and the transmission range switch.n NO - Go to 15.

15. | Shift to the R position.

16. | Measure the voltage between PCM connector terminals C10 and A23 or A24. Is there voltage? YES - Repair open in the wire between PCM connector terminal C10 and the transmission range switch.n NO - Go to 17.

17. | Shift to the P or N position.

18. | Measure the voltage between PCM connector terminals C12 and A23 or A24. Is there voltage? YES - Repair open in the wire between PCM connector terminal C12 and the transmission range switch.n NO - Go to 19.

19. | Shift to the S position.

20. | Measure the voltage between PCM connector terminals C9 and A23 or A24. Is there voltage? YES - Repair open in the wire between PCM connector terminal C9 and the transmission range switch.n NO - Go to 21.

21. | Shift to the L position.

22. | Measure the voltage between PCM connector terminals C11 and A23 or A24. Is there voltage? YES - Repair open in the wire between PCM connector terminal C11 and the transmission range switch.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
