DTC P0705: Transmission Range Switch Multiple Shift Position Input

NOTE:

Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the Fuel and Emissions Systems How to Troubleshoot the CVT System(CVT System) .
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
P0705 Transmission Range Switch Multiple Shift Position Input

1. Problem verification:

1. Turn the vehicle to the ON mode.

2. Compare the transmission range switch signal inputs with the HDS to the following table, in each shift lever position/mode.

Signal	Threshold						Current conditions
Signal	P	R	N	D	S	L	Values	Unit
A/T P Switch	ON	OFF	OFF	OFF	OFF	OFF
A/T R Switch	OFF	ON	OFF	OFF	OFF	OFF

Signal	Threshold						Current conditions
Signal	P	R	N	D	S	L	Values	Unit
A/T N Switch	OFF	OFF	ON	OFF	OFF	OFF
A/T D Switch	OFF	OFF	OFF	ON	OFF	OFF
A/T S Switch	OFF	OFF	OFF	OFF	ON	OFF
A/T L Switch	OFF	OFF	OFF	OFF	OFF	ON
Forward Switch	OFF	OFF	OFF	ON	ON	ON
Reverse Switch(ATPRVS)	OFF	ON	OFF	OFF	OFF	OFF

Do the transmission range switch signals match?

YES

Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot. Check the freeze data/on-board snapshot for the circuit signal that does not match and check for intermittent short on those circuits.

The failure is duplicated. Go to step 2.

2. Transmission range switch signal check:

1. Compare the transmission range switch signal inputs with the HDS to the following table, in each shift lever position/mode.

Signal	Threshold						Current conditions
Signal	P	R	N	D	S	L	Values	Unit
A/T P Switch	ON	OFF	OFF	OFF	OFF	OFF
A/T R Switch	OFF	ON	OFF	OFF	OFF	OFF
A/T N Switch	OFF	OFF	ON	OFF	OFF	OFF
A/T D Switch	OFF	OFF	OFF	ON	OFF	OFF
A/T S Switch	OFF	OFF	OFF	OFF	ON	OFF
A/T L Switch	OFF	OFF	OFF	OFF	OFF	ON
Forward Switch	OFF	OFF	OFF	ON	ON	ON
Reverse Switch(ATPRVS)	OFF	ON	OFF	OFF	OFF	OFF

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

YES

Go to step 4.

Records the abnormal circuit, then go to step 3.

3. Transmission range switch check:

1. Turn the vehicle to the OFF (LOCK) mode.

2. Disconnect the following connector.

Transmission range switch 10P connector

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

A/T R Switch	4	ATP-R
A/T N Switch	9	ATP-N

4. Turn the vehicle to the ON mode.

5. Compare the transmission range switch signal inputs with the HDS.

Signal	Threshold						Current conditions
Signal	P	R	N	D	S	L	Values	Unit
A/T P Switch	ON	OFF	OFF	OFF	OFF	OFF
A/T R Switch	OFF	ON	OFF	OFF	OFF	OFF
A/T N Switch	OFF	OFF	ON	OFF	OFF	OFF
A/T D Switch	OFF	OFF	OFF	ON	OFF	OFF
A/T S Switch	OFF	OFF	OFF	OFF	ON	OFF
A/T L Switch	OFF	OFF	OFF	OFF	OFF	ON
Forward Switch	OFF	OFF	OFF	ON	ON	ON
Reverse Switch(ATPRVS)	OFF	ON	OFF	OFF	OFF	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.

	ATP-P	ATP-R	ATP-N	ATP-D	ATP-S	ATP-L	ATP-FWD	ATP-RVS
PCM	C34	C27	C24	C25	C43	C44	C26	C23
Transmission range switch	5	4	9	3	8	2	6	10

Replace the transmission range switch .

4. Transmission range switch check:

1. Turn the vehicle to the OFF (LOCK) mode.

2. Disconnect the following connector.

Transmission range switch 10P connector

3. Turn the vehicle to the ON mode.

4. Check the transmission range switch signal input that remained ON with the HDS.

Signal	Threshold						Current conditions
Signal	P	R	N	D	S	L	Values	Unit
A/T P Switch	ON	OFF	OFF	OFF	OFF	OFF
A/T R Switch	OFF	ON	OFF	OFF	OFF	OFF
A/T N Switch	OFF	OFF	ON	OFF	OFF	OFF
A/T D Switch	OFF	OFF	OFF	ON	OFF	OFF
A/T S Switch	OFF	OFF	OFF	OFF	ON	OFF
A/T L Switch	OFF	OFF	OFF	OFF	OFF	ON
Forward Switch	OFF	OFF	OFF	ON	ON	ON
Reverse Switch(ATPRVS)	OFF	ON	OFF	OFF	OFF	OFF

Do any transmission range switch signals remain ON?

YES

The transmission range switch is OK. Go to step 5.

Replace the transmission range switch .

5. Shorted wire check (corresponding line):

1. Turn the vehicle to the OFF (LOCK) mode.

2. Jump the SCS line with the HDS, and wait more than 1 minute.

3. Disconnect the following connector.

PCM connector C (51P)

4. Check for continuity between the connector terminal on the circuit that remained ON in step 4 and body ground; refer to the following table.

Signal	Transmission range switch 10P connector
Signal	Terminal number	Terminal name
A/T P Switch	5	ATP-P
A/T R Switch	4	ATP-R
A/T N Switch	9	ATP-N
A/T D Switch	3	ATP-D
A/T S Switch	8	ATP-S
A/T L Switch	2	ATP-L
Forward Switch	6	ATP-FWD
Reverse Switch	10	ATP-RVS

Does the circuit that indicated ON have continuity to body ground?

YES

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

The wires are OK. Update the PCM if it does not have the latest software . If the PCM was updated, replace the PCM , then recheck. If DTC P0705 goes away and the PCM was updated, troubleshooting is complete. If DTC P0705 goes away and the PCM was substituted, replace the original PCM .
