16. Reconnect all connectors.

17. Update the PCM if it does not have the latest

software (see page 11-227), or substitute a known-
good PCM (see page 11-7).

18. Start the engine with the shift lever in P. Shift to N,

then shift to R while pressing the brake pedal, and
wait for at least 2 seconds.

19. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals between the transmission range switch
and the PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-7), then go to step
18. If the PCM was substituted, go to step 1.

Go to step 20.

20. Monitor the OBD STATUS for P1717 in the DTCs

MENU with the HDS.

If the PCM was updated, troubleshooting is

complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 19,
go to the indicated DTC’s troubleshooting.

If the HDS indicates FAILED, check for poor

connections or loose terminals between the
transmission range switch and the PCM. If the PCM
was updated, substitute a known-good PCM
(see page 11-7), then go to step 18. If the PCM was
substituted, go to step 1. If the HDS indicates NOT
COMPLETED, go to step 18.
