DTC P0705: Transmission Range Switch Circuit (Multiple Shift-position Input)

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How to Troubleshoot A/T Systems

- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Clear the DTC with the HDS.

2. Start the engine.

3. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in each position, and monitor the OBD STATUS for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate FAILED?
YES - Go to step 4.

NO - Intermittent failure, the system is OK at this time. Check for an intermittent short in the wire between the transmission range switch and the PCM. If the HDS indicates NOT COMPLETED, return to step 2 and recheck.


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

5. Disconnect the transmission range switch subharness connector.

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

7. Check the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T S Switch, Forward Switch (ATP FWD), and Reverse Switch (ATP RVS) inputs with the HDS in the A/T data list.

Do any of the inputs indicate ON?
YES - Repair short in the circuit that indicates ON:
'07 Model

- A/T P switch circuit: Between PCM connector terminal B13 and transmission range switch subharness connector terminal No. 7.

- A/T R switch circuit: Between PCM connector terminal B14 and transmission range switch subharness connector terminal No. 8.

- A/T N switch circuit: Between PCM connector terminal B12 and transmission range switch subharness connector terminal No. 3.

- A/T D switch circuit: Between PCM connector terminal B21 and transmission range switch subharness connector terminal No. 9.

- A/T S switch circuit: Between PCM connector terminal B15 and transmission range switch subharness connector terminal No. 4.

- Forward switch (ATP FWD) circuit: Between PCM connector terminal B28 and transmission range switch subharness connector terminal No. 5.

- Reverse switch (ATP RVS) circuit: Between PCM connector terminal B22 and transmission range switch subharness connector terminal No. 2.

'08-09 Models

- A/T P switch circuit: Between PCM connector terminal B13 and transmission range switch connector terminal No. 7.

- A/T R switch circuit: Between PCM connector terminal B14 and transmission range switch connector terminal No. 8.

- A/T N switch circuit: Between PCM connector terminal B12 and transmission range switch connector terminal No. 3.

- A/T D switch circuit: Between PCM connector terminal B21 and transmission range switch connector terminal No. 9.

- A/T S switch circuit: Between PCM connector terminal B15 and transmission range switch connector terminal No. 4.

- Forward switch (ATP FWD) circuit: Between PCM connector terminal B28 and transmission range switch connector terminal No. 5.

- Reverse switch (ATP RVS) circuit: Between PCM connector terminal B22 and transmission range switch connector terminal No. 2.

Go to step 15 after repairing the circuit.

NO - Go to step 8.


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

9. Inspect the transmission range switch. Transmission Range Switch Test

Is the test result OK?
YES - Connect the transmission range switch connector, then go to step 10.

NO - Replace the transmission range switch or switch subharness ('07 model), Service and Repair then go to step 15.


10. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. How to Troubleshoot A/T Systems

11. Start the engine.

12. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in each position.

13. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0705 indicated?
YES - Check for poor connections and loose terminals at the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 14.


14. Monitor the OBD STATUS for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. Service and Repair If any other DTCs were indicated on step 13, go to the indicated DTC's troubleshooting.

NO - Check for poor connections and loose terminals at the transmission range switch and the PCM. If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 11 and recheck.


15. Clear the DTC with the HDS.

16. Start the engine.

17. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in each position.

18. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0705 indicated?
YES - Check for poor connections and loose terminals at the transmission range switch and the PCM, then return to step 15 and recheck.

NO - Go to step 19.


19. Monitor the OBD STATUS for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated on step 18, go to the indicated DTC's troubleshooting.

NO - Check for poor connections and loose terminals at the transmission range switch and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 16 and recheck.
