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
