DTC P1717

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

NOTE: Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016), or How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015) .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC (A/T)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   - 2. Check the parameter(s) below with the HDS with the shift lever in R.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   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 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. Determine possible failure area (transmission range switch, others)

   -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	Transmission range switch 10P connector No. 5 (PNK)
   Terminal B	Body ground

   - 4. Turn the vehicle to the ON mode.

   - 5. Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   Reverse Switch(ATPRVS)	ON

   Do the current condition(s) match the threshold?

   YES 

   Replace the transmission range switch .

   NO 

   Go to step 3.

3. Open wire check (ATPRVS line)

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

   - 2. Remove the jumper wire.

   - 3. Jump the SCS line with the HDS.

   - 4. Disconnect the following connector.

   PCM connector B (51P) - Refer to: How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016), or How to Troubleshoot the Fuel and Emissions Systems

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

   Test condition	Vehicle OFF (LOCK) mode
   	Transmission range switch 10P connector: disconnected
   	PCM connector B (51P): disconnected
   Test circuit	ATPRVS
   Test point 1	Transmission range switch 10P connector No. 5 (PNK)
   Test point 2	PCM connector B (51P) No. 38 (PNK)

   Is there continuity?

   YES 

   The ATPRVS wire is OK. Replace the PCM - Refer to: PCM Removal and Installation (2014 2015), or PCM Removal and Installation (2016) .

   NO 

   Repair an open in the ATPRVS wire between the transmission range switch and the PCM.
