DTC P0706:

Transmission Range Switch (Open)

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information. How To Troubleshoot The A/T System
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Make sure the shift cable is adjusted properly.

2. Turn the ignition switch to ON (II).

3. Compare the ATPP, ATPR, ATPN, ATPD, ATP2, ATP1, ATPFWD, and ATPRVS inputs with the HDS to the following table, in each shift lever position.










Do the transmission range switch signals match?

YES -

Intermittent failure, the system is OK at this time.�

NO -

Go to step 4.

4. Compare the ATPP, ATPR, ATPN, ATPD, ATP2, ATP1, ATPFWD, and ATPRVS inputs with the HDS to the table in step 3, in each shift lever position.

Do all shift positions remain OFF?

YES -

Go to step 14.

NO -

Record the input that did not indicates ON, then go to step 5.

5. Turn the ignition switch to LOCK (0).

6. Disconnect the transmission range switch connector.

7. Connect the transmission range switch connector terminal that did not indicates ON in step 4 to body ground with a jumper wire.

8. Turn the ignition switch to ON (II).

9. Check the transmission range switch signal that did not indicate ON with the HDS.

Does the transmission range switch indicate ON?

YES -

Replace the transmission range switch Service and Repair.�

NO -

Go to step 10.

10. Turn the ignition switch to LOCK (0).

11. Jump the SCS line with the HDS.

12. Disconnect PCM connector B (44P) (K24Z1 engine) or B (49P) (K24Z6 engine).

13. Check for continuity between the transmission range switch connector terminal and the PCM terminal of the input which indicated OFF. Refer to the following table.









Is there continuity?

YES -

Replace the PCM; K24Z6 engine Service and Repair.�

NO -

Repair open in the wire between the transmission range switch and the PCM.�

14. Turn the ignition switch to LOCK (0).

15. Disconnect the transmission range switch connector.

16. Check for continuity between transmission range switch connector terminal No. 10 and body ground.





Is there continuity?

YES -

Replace the transmission range switch Service and Repair.�

NO -

Repair open in the wire between the transmission range switch and ground (G101), or repair poor ground (G101).�
