intermittent short to body ground in the wires
between the transmission range switch and the
PCM, then go to step 1. If the HDS indicates NOT
COMPLETED, go to step 48.
52. Reconnect all connectors.

known-good PCM (see page 11-7), then go to step
54. If the PCM was substituted, go to step 1.
Go to step 57.
57. Monitor the OBD STATUS for P0705 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 56,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for
intermittent short to body ground in the wires
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 54. If the
PCM was substituted, go to step 1. If the HDS
indicates NOT COMPLETED, go to step 54.

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. Block the rear wheels and raise the front of the vehicle, make sure it is securely supported, and
allow the front wheels to rotate freely, or raise the
vehicle on a lift.
4. Start the engine, disable the VSA by pressing the VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
40 km/h (25 mph), then slow down and stop the
wheels.
5. Monitor the OBD STATUS for P0706 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
poor connections or loose terminals between the
transmission range switch and the PCM. If the HDS
indicates NOT COMPLETED, go to step 4.
6. Turn the ignition switch to LOCK (0).
7. Inspect the transmission range switch (see page 14-265).
Go to step 8.
Replace the transmission range switch
(see page 14-267), then go to step 25.
8. Adjust the shift cable (see page 14-259). 9. Turn the ignition switch to ON (II).
10. Clear the DTC with the HDS.
11. Start the engine, disable the VSA by pressing the VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
40 km/h (25 mph), then slow down and stop the
wheels.
12. Monitor the OBD STATUS for P0706 in the DTCs MENU with the HDS.
Go to step 13.
If the HDS indicates PASSED, troubleshooting
is complete. If the HDS indicates NOT COMPLETED,
go to step 11.
13. Shift to D, and check the Forward Switch (ATPFWD) andA/TDSwitchintheDATALISTwiththeHDS.
Go to step 14.
Go to step 18.
14. Shift to S, and check the Forward Switch (ATPFWD) andA/TSSwitchintheDATALISTwiththeHDS.
Go to step 15.
Go to step 18.
