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. Problem verification:

-1. Turn the ignition switch to ON (II).

-2. Compare the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T 2 Switch, A/T 1 Switch, Forward Switch(ATPFWD), and Reverse Switch(ATPRVS) inputs with the HDS to the following table, in each shift lever position.






o: ON / x: OFF





Do the transmission range switch signals match?
-YES- Intermittent failure, the system is OK at this time.
-NO- The failure is duplicated. Go to step 2.

2. Transmission range switch signal check:

-1. Compare the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T 2 Switch, A/T 1 Switch, Forward Switch(ATPFWD), and Reverse Switch(ATPRVS) inputs with the HDS to the following table, in each shift lever position.






o: ON / x: OFF





Are any transmission range switch signals ON in all shift lever positions?
-YES- Go to step 4.
-NO- Record the abnormal circuit, then go to step 3.

3. Transmission range switch check:

-1. Turn the ignition switch to LOCK (0).

-2. Disconnect the following connector.





-3. Connect the transmission range switch connector terminal that incorrectly indicates ON in step 2 to ground with a jumper wire.

-4. Turn the ignition switch to ON (II).

-5. Compare the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T 2 Switch, A/T 1 Switch, Forward Switch(ATPFWD), and Reverse Switch(ATPRVS) inputs with the HDS to the following table.






o: ON / x: OFF





Do multiple transmission range switch signals indicate ON?
-YES- The transmission range switch is OK. Repair a short in the wires between the corresponding transmission range switch connector terminal and the PCM. Refer to the following table.





-NO- Replace the transmission range switch Service and Repair.

4. Transmission range switch check:

-1. Turn the ignition switch to LOCK (0).

-2. Disconnect the following connector.





-3. Turn the ignition switch to ON (II).

-4. Check the transmission range switch signal input that remained ON with the HDS to the following table.






o: ON / x: OFF





Do any transmission range switch signals remain ON?
-YES- The transmission range switch is OK. Go to step 5.
-NO- Replace the transmission range switch Service and Repair.

5. Shorted wire check (ATP-P, ATP-R, ATP-N, ATP-D, ATP-D3, ATP-1, ATP-FWD, ATP-RVS line):

-1. Check for continuity to ground in the circuit that remained ON in step 4.

Does the circuit that indicated ON have continuity to ground?
-YES- Repair a short to ground in the wire between the corresponding transmission range switch connector terminal and the PCM.
-NO- The wires are OK. Update the PCM if it does not have the latest software PCM Update. If the PCM was updated, replace the PCM Service and Repair.
