1.
Problem verification:

Problem verification
?1.
Make sure the shift cable is properly adjusted.

?2.
Turn the vehicle to the ON mode.

?3.
Shift the transmission to R position/mode.

?4.
Check the parameter(s) below with the HDS.

Do the current condition(s) match the threshold?

     
YES
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the transmission range switch and the PCM. 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 check:

Transmission range switch check
?1.
Do the transmission range switch test.

Is the transmission range switch OK?

     
YES
     
     
     
The transmission range switch is OK. Go to step 3.
     
NO
     
     
     
Check for proper transmission range switch installation, then recheck. If the transmission range switch installation is OK, replace the transmission range switch.?
3.
Open wire check (ATP-RVS line):

Open wire check (ATP-RVS line)
?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.
Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode
 
Transmission range switch 10P connector: disconnected
Test point 1
Transmission range switch 10P connector No. 10
Test point 2
Body ground


Is there voltage?

     
YES
     
     
     
The ATP-RVS wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P1717 goes away and the PCM was updated, troubleshooting is complete. If DTC P1717 goes away and the PCM was substituted, replace the original PCM.?
     
NO
     
     
     
Repair an open in the ATP-RVS wire between the transmission range switch and the PCM.?
