NOTE: 

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

DTC (A/T)

  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.

      A/T P Switch A/T R Switch A/T N Switch A/T D Switch A/T S Switch Forward Switch (ATPFWD) Reverse Switch (ATPRVS)
    P ON OFF OFF OFF OFF OFF OFF
    R OFF ON OFF OFF OFF OFF ON
    N OFF OFF ON OFF OFF OFF OFF
    D OFF OFF OFF ON OFF ON OFF
    L OFF OFF OFF OFF ON ON OFF
    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
    Forward Switch (ATPFWD)
    Reverse Switch (ATPRVS)

    Do the 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 table in step 1-2, in each shift lever position.

    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    
    Forward Switch (ATPFWD)    
    Reverse Switch (ATPRVS)    

    Are any 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 vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the following connector.

    Transmission range switch 10P connector

    - 3. Connect terminals A and B with a jumper wire.

    Terminal A Corresponding circuit (incorrectly indicated ON in step 2); refer to following table
    Terminal B Body ground
    Connector Signal Circuit Terminal
    Transmission range switch 10P connector A/T P Switch ATP-P/ATPP No. 9
    A/T R Switch ATP-R/ATPR No. 8
    A/T N Switch ATPN No. 2
    A/T D Switch ATPD No. 7
    A/T S Switch ATPS (ATPL) No. 6
    Forward Switch (ATPFWD) ATPFWD No. 1
    Reverse Switch (ATPRVS) ATPRVS No. 5

    - 4. Turn the vehicle to the ON mode.

    - 5. Check the parameter (s) below 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    
    Forward Switch (ATPFWD)    
    Reverse Switch (ATPRVS)    

    Do multiple 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/ATPP ATP-R/ATPR ATPN ATPD ATPS (ATPL) ATPFWD ATPRVS
    PCM connector - Refer to:
    PCM Connector for Inputs and Outputs (16-20 6-Speed A/T)
    A37 A16 B30 B23 B34 B29 B38
    Transmission range switch 9 8 2 7 6 1 5

    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 parameter (s) below that remained ON 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    
    Forward Switch (ATPFWD)    
    Reverse Switch (ATPRVS)    

    Do any signals remain ON?

    YES 

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

    NO 

    Replace the transmission range switch .

  5. Shorted wire check (ATP-P/ATPP, ATP-R/ATPR, ATPN, ATPD, ATPS (ATPL), ATPFWD, ATPRVS 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 connectors.

    PCM connector A (51P)
    PCM connector B (51P)

    - 4. Check for continuity between these test points and body ground individually.

    Test condition Vehicle OFF (LOCK) mode
    Transmission range switch 10P connector: disconnected
    PCM connector A (51P): disconnected
    PCM connector B (51P): disconnected

    Does the circuit that indicated ON have continuity to body 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. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM - Refer to: PCM Removal and Installation (6-Speed A/T, 16-18 9-Speed A/T) .
