DTC P0705:

Short in Transmission Range Switch Circuit (Multiple Shift-Position Input)

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information Reading and Clearing Diagnostic Trouble Codes.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

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





(circle): ON x: OFF

Do the transmission range switch signals match?

YES -

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

NO -

Go to step 3.

3. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2, in each shift lever position.

Are any transmission range switch signals ON in all shift lever positions?

YES -

Go to step 9.

NO -

Record any input that incorrectly indicated ON, then go to step 4.

4. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

5. Disconnect the transmission range switch connector.

6. Connect the transmission range switch connector terminal that incorrectly indicates ON in step 3 to body ground with a jumper wire.

7. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

8. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2.

Do multiple transmission range switch signals indicate ON?

YES -

Repair short in the wires between the transmission range switch and the PCM, refer to the following table.�





NO -

Replace the transmission range switch Service and Repair.�

9. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

10. Disconnect the transmission range switch connector.

11. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

12. Check the abnormal transmission range switch signal that remained on with the HDS.

Do any transmission range switch signals remain ON?

YES -

Go to step 13.

NO -

Replace the transmission range switch Service and Repair.�

13. Check for continuity to body ground in the circuit which remained ON, see table in step 2.

Does the circuit that indicated ON have continuity to ground?

YES -

Repair a short to body ground in the wire between the transmission range switch and the PCM.�

NO -

Update the PCM if it does not have the latest software ECM/PCM Update. If the PCM was updated, replace the PCM Service and Repair.�
