NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
 This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. With the brake pedal pressed, move the shift lever through all positions. Stop for at least 1 second in
each position.
5. Monitor the OBD STATUS for P0705 in the DTCs MENU with the HDS.
Go to step 6.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
intermittent short to body ground in the wires
between the transmission range switch and the
PCM. If the HDS indicates NOT COMPLETED, go to
step 3.
6. Turn the ignition switch to LOCK (0).
7. Inspect the transmission range switch (see page 14-265).
With the switch connector disconnected, go
to step 8.
Replace the transmission range switch
(see page 14-267), then go to step 45. 8. Turn the ignition switch to ON (II).
9. Measure the voltage between transmission range
switch connector terminals No. 6 and No. 10.
Go to step 15.
Go to step 10.
