NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information See HOW TO TROUBLESHOOT THE A/T SYSTEM or HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS .
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

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

A/T R Switch signal check:

1. Turn the ignition switch to ON (II).

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

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
A/T R Switch	ON

Do the current condition(s) match the threshold?

YES : The A/T R Switch signal is OK. Go to step 2.

NO : Check for proper transmission range switch installation, adjust the shift cable See A/T SHIFT CABLE ADJUSTMENT or A/T SHIFT CABLE REMOVAL AND INSTALLATION , then recheck. If the transmission range switch and the shift cable are OK, go to step 3.

Reverse Switch(ATPRVS) signal check:

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

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

Do the current condition(s) match the threshold?

YES : The Reverse Switch(ATPRVS) signal is OK. Intermittent failure, the system is OK at this time.

NO : Go to step 3.

Open wire check (ATP RVS line):
- 1. Turn the ignition switch to LOCK (0).
- 2. Disconnect the following connector.
  Transmission range switch 10P connector
- 3. Turn the ignition switch to ON (II).
- 4. Measure the voltage between test points 1 and 2.
  Test condition IG ON (II)
  
  Transmission range switch 10P connector: disconnected
  
  Test circuit ATP RVS
  
  Test point 1 Transmission range switch 10P connector No. 5 (WHT/RED)
  
  Test point 2 Body ground

Is there battery voltage?

YES : The ATP RVS wire is OK. Go to step 4.

NO : Repair an open in the ATP RVS wire between the transmission range switch and the PCM, then do the repair verification .
Transmission range switch check:
- 1. Check for continuity between test points 1 and 2.
  Test condition IG LOCK (0)
  
  Transmission range switch 10P connector: disconnected
  
  Test circuit ATP RVS, GND
  
  Test point 1 Transmission range switch 10P connector No. 5
  
  Test point 2 Transmission range switch 10P connector No. 6

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

YES : The transmission range switch is OK. Update the PCM if it does not have the latest software See PCM REMOVAL AND INSTALLATION or PCM UPDATE , or substitute a known-good PCM See PCM REMOVAL AND INSTALLATION or PCM UPDATE , then do the repair verification .

NO : REPLACE THE TRANSMISSION RANGE SWITCH , then do the repair verification .
