DTC P1717  : Transmission Range Switch ATP RVS Switch (Open or Short)

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. 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.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   A/T R Switch	ON
   Reverse Switch (ATPRVS)	ON

   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 TCM. 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. 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 (female terminals) No. 10 :
   Test point 2	Body ground

   Is there about 5 V?

   YES 

   The ATP-RVS wire is OK. Go to step 3.

   NO 

   Repair an open in the ATP-RVS wire between the transmission range switch and the TCM.

3. Transmission range switch check

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

   -2. Check for continuity between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Transmission range switch 10P connector: disconnected
   Test point 1	Transmission range switch 10P connector (male terminals) No. 1 :
   Test point 2	Transmission range switch 10P connector (male terminals) No. 10 :

   Is there continuity when the shift lever is in R position/mode, and no continuity when the shift lever is shifted to any other position/mode?

   YES 

   The transmission range switch is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good TCM , then recheck. If this DTC goes away and the TCM was substituted, replace the original TCM .

   NO 

   Check for proper transmission range switch installation, then recheck. If the transmission range switch installation is OK, replace the transmission range switch .
