DTC P0705:

Transmission Range Switch (Multiple Shift-position Input)

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the 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. Turn the ignition switch to ON (II).

2. Move the shift lever through all positions, monitor the ATPP, ATPR, ATPN, ATPD, ATPD3, ATP2-1, ATPS, ATPFWD, and ATPRVS inputs with the HDS.
Check for an ON-input that should be OFF in the specific position base on the following tables.

Seven-position Transmission





Five-position Transmission





Are there any failed ON-inputs?

YES -

Go to step 3.

NO -

Intermittent failure, the system is OK at this time.

3. Disconnect the transmission range switch connector.

4. Check that the failed input-signal remains ON with the HDS.

Does the failed input-signal remain ON?

YES -

Go to step 5.

NO -

Replace the transmission range switch Service and Repair.

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

6. Jump the SCS line with the HDS.

7. Disconnect PCM connector B (49P).

8. Check for continuity between transmission range switch connector terminal of the failed ON-input wire and body ground.

Seven-position Transmission





Five-position Transmission





Is there continuity?

YES -

Repair a short in the wire between the transmission range switch connector and the PCM.

NO -

Go to step 9.

9. Check for continuity between the failed ON-input line terminal and all other terminals at the transmission range switch connector in the table in step 8.

Is there continuity between any terminals?

YES -

Repair a short in the wires between the transmission range switch connector and the PCM.

NO -

Replace the PCM.
