DTC P0705  : Transmission Range Switch Multiple Shift Position Input

NOTE: 

• Before you troubleshoot, review the General Troubleshooting Information .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC (CVT)

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.

   Signal	Threshold						Current conditions
   	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

   Signal	Threshold						Current conditions
   	P	R	N	D	S	L	Values	Unit
   A/T S Switch	OFF	OFF	OFF	OFF	ON	OFF
   A/T L Switch	OFF	OFF	OFF	OFF	OFF	ON
   ATP-FWD	OFF	OFF	OFF	ON	ON	ON
   ATP-RVS	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.

   NO 

   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.

   Signal	Threshold						Current conditions
   	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
   ATP-FWD	OFF	OFF	OFF	ON	ON	ON
   ATP-RVS	OFF	ON	OFF	OFF	OFF	OFF

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

   YES 

   Go to step 4.

   NO 

   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.

   -4. Turn the vehicle to the ON mode.

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

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

   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

   NO 

   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	Current conditions
   	Values	Unit
   A/T P Switch
   A/T R Switch

   Signal	Current conditions
   	Values	Unit
   A/T N Switch
   A/T D Switch
   A/T S Switch
   A/T L Switch
   Forward Switch
   Reverse Switch (ATPRVS)

   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 .

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.

   NOTE:  This step must be done to protect the PCM from damage.

   -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 (female terminals) :
   	Terminal number
   A/T P Switch	5
   A/T R Switch	4
   A/T N Switch	9
   A/T D Switch	3
   A/T S Switch	8
   A/T L Switch	2
   Forward Switch	6
   Reverse Switch	10

   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.

   NO 

   The wires are OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or replace the original PCM .
